What matters most is squeezing as much usable performance as possible out of your PDP. Some of these recommendations overlap, so read closely and pick the one that works best for you.

TL;DR: The best Walther PDP upgrades you can buy are a pistol light and red dot. These accessories aren't cheap, but they'll make you drastically more effective -- especially at night. For a faster, smoother shooting experience, the Walther Dynamic Performance Trigger and ZRTS Ultra Mass Guide Rod are a cherry on top of an already phenomenal pistol.

How We Tested The Best Walther PDP Upgrades

I’ve used each of the upgrades on this list. You can still find some of them on my test mule PDP. Others appeared at multi-day media events, which gave me enough range time to form an educated opinion about them.

Regardless of how my hands-on experience came to be, I’ve put hundreds of rounds through a PDP with each of the upgrades here. That includes full-size, compact, F-Series, and Match Steel Frame pistols.

Effectiveness: Reliability, Accuracy & Speed

Some of these PDP upgrades directly affect your ability to put rounds on target. I'm particularly talking about irons sights, optics, and weapon lights.

I've fired hundreds of rounds or more using the night sights, red dots, and pistol lights you see in this article. They've proven their reliability through high round counts, and their durability in austere environments ranging from the desert to deep snow.

Comfort

Other upgrades may not affect how your PDP shoots, but they will affect how much you enjoy carrying it.

When testing holsters, I found two that support the PDP's weight and put minimal stress on my waistline. These include IWB and OWB options. I've worn each of these extensively during physically active training sessions and pistol courses.

Value

Like me, I'm sure you have to be choosy about where you spend your money. I assessed the bang for the buck, so to say, for each product on this list. They're all great, but some will deliver more noticeable returns than others.

Start with the low-hanging fruit and work your way up from there.

How to Choose The Best Walther PDP Upgrades

The Walther PDP is a versatile platform. Your first job, before spending a single dollar on modifications and upgrades, is setting a goal. What, specifically, do you want your PDP to do better?

Walther PDP PPT 3

Concealed Carry

If you’re setting up a dedicated concealed-carry pistol, you'll want to keep it small and light. Maybe opt for CCW-friendly variants of my picks, like a Trijicon RMRcc or Surefire XR2.

I like to keep my concealed carry guns simple. Firearm manufacturers do more testing than I ever could, so I stick to their designs when I can. Fewer parts mean fewer things to break, and fewer questions to answer from a legal standpoint.

That said, I strongly recommend looking at adding a pistol light and red dot to your concealed carry setup. A comfortable holster like the BlackPoint Tactical FO3 is a must.

Home Defense

A dedicated home defense pistol can afford to be big (in fact, some extra weight can be a benefit when it comes to recoil control) so focus on increasing capacity and making sure you have enough light to positively identify who’s in your home.

Extended magazine basepads, like the ones you see here from ZR Tactical, increase capacity by as much as four rounds. A suppressor can preserve your hearing when you need it most.

Once again, don't overlook a good weapon light and a red dot.

Competition

Competitive shooters need to think about class regulations, so start there and focus on upgrades that can give you a speed advantage.

ZR Tactical's Ultra Mass Guide Rod is deceptively good at reducing felt recoil. The same goes for a brass backstrap. If you didn't buy one of Walther's more competition-focused PDP's, a flared magazine well and Dynamic Performance Trigger will pay off nicely for you.

Best Walther PDP Upgrades

1. Cloud Defensive EPL - Best Pistol Light

Quick Verdict: After our recent pistol light comparison, the Cloud Defensive EPL is our current favorite. It matches many rifle lights in terms of output, with enough power to cut through all kinds of photonic barriers and establish positive identification as far out as you care to shoot a pistol. Intuitive, comfortable controls round out an already excellent light. Yes, it's expensive, but we can't argue with the performance.

Pros

  • Phenomenal output
  • Duty-grade build quality
  • Wide range of holster compatibility

Cons

  • Very bright for indoor use
  • Some pretty decent lights cost half as much

Specs

  • Power: 1,200 lumens
  • Intensity: 52,000 candela
  • Battery: 18350
  • Modes: Constant, momentary
  • Waterproof: IPX7
  • Length: 3.75"
  • Weight: 4 oz
  • Country of Origin: USA

Why We Love It

The Cloud Defensive EPL is refined yet rugged ,just like the Walther PDP.

Cloud Defensive EPL

This pistol light recently won our roundup of the Best Pistol Lights with astounding brightness, intuitive controls, and sturdy construction that we'd trust in the harshest environments.

Power comes in at 1,200 lumens and 52,000 candela. Allow me to put that in practical terms with this photo that we took using the EPL as a handheld light for safety.

Cloud Defensive EPL

Pistol engagement distances tend to be very close, but there are always exceptions to the rule. This light actually allowed us to establish positive identification at 50 yards -- that's a a rare feat for a pistol light. It also provided more than enough power to pierce heavy gun smoke from rapid strings of fire.

At closer distances, it was as bright as many rifle lights. Not only could I find, identify, and engage paper targets at 25 yards in the dark, I could actually spot my impacts. Indoors, the EPL lit up rooms corner to corner with authority.

I think I like the paddle-style controls better than SureFire's stiff toggle, too. This light really won me over.

If spending close to $300 on an EPL isn't an option, check out the Streamlight TLR-1 HL. While it can't match the EPL's performance or build quality, it does a really nice job for half the price. It's consistently one of my value picks in the category.

2. Trijicon RMR Type 2 Adjustable - Best Open Emitter Red Dot

Quick Verdict: The Trijicon RMR has achieved a legendary reputation for toughness and reliability, so it’s a natural choice for the rough-and-tumble PDP. While the optical quality could be better, there's no open-emitter I trust more. The RMR has excelled in every durability test I've conducted. The 3.25-MOA reticle is useful for speed and precision shooting, and now you can get it in green.

Best Open Emitter Red Dot

Pros

  • Famously reliable and nearly indestructible
  • Improved battery compartment protection
  • You control the brightness

Cons

  • Noticeable tint and distortion
  • View gets crowded with suppressor-height sights

Specs

  • Emitter: Open
  • Reticles: 1-MOA, 3.25-MOA, 6.5-MOA red dot, 3.25-MOA green not
  • Brightness Settings: 6 daylight, 2 night vision
  • Auto On/Off: Defaults to auto brightness after 16.5 hours
  • Adjustment: 1 MOA
  • Window: 0.87” x 0.63”
  • Footprint: RMR
  • Battery: CR2032
  • Country of Origin: USA

Why We Love It

The Trijicon RMR Type 2 Adjustable is a legend in the world of pistol red dots. It's a combat-hardened platform trusted by military and law-enforcement professionals around the world.

Trijicon RMR

I’ve used a ton of pistol optics, and while the RMR isn’t perfect, I understand its appeal.

The window has a strong blue tint. It’s not exactly distortion-free. But this isn’t a competition optic; it’s meant to survive the worst conditions combat can throw at it.

Here's a clip from a drop test I did with the RMR on a Glock 45 so you can see what I mean.

If my personal experience with the RMR isn't convincing enough, consider that it's been used for decades by military personnel on everything from sidearms to the M249 SAW (that's actually how I first experienced red dots -- an RMR as a backup optic on on a SAW).

These days, I use the RMR on my own PDP for home defense. The controls are simple to operate and I know I can always trust it.

At home or in a squad car, the tinted glass and slight pinch distortion aren't anything to worry about. Removing the optic to replace the battery is annoying, but at least Trijicon added a bead of silicone to improve waterproofing.

On the other hand, I wouldn't recommend the RMR if you're upgrading your PDP for competition. The Trijicon SRO is a better option for that, or you can do what I would do: save some money, buy a Vortex Defender-XL, and enjoy nearly flawless optical quality.

3. Colt Optics MRS-1 - Best Enclosed Emitter Red Dot

Quick Verdict: The Colt Optics MRS-1 mad a big splash as the brand's entry into the optic market. Time will tell just how good it is, but it appears to be one of the best enclosed emitter pistol red dots you can buy. The massive controls are easy to use by feel or with gloves, whether you're right- or left-handed. The window is massive and beautifully clear. A few more reticle options would be nice, but that's about the only criticism we have for the MRS-1.

Pros

  • Outstanding button size and placement

  • Only one reticle option

Specs

  • Emitter: Enclosed
  • Reticles: 3-MOA red dot
  • Brightness Settings: 8 daylight, 4 night vision
  • Auto On/Off: Yes
  • Adjustment: 1 MOA
  • Window: 0.83" x 0.79"
  • Footprint: ACRO

Why We Love It

We were as surprised as you were when Colt announced a line of optics, and the Colt Optics MRS-1 is everything we hoped it would be.

Make no mistake, this is a true duty optic. The solid metal housing feels like a tank. While we didn't do any torture testing with our pre-production MRS-1, I have no doubts about its toughness.

Pay special attention to those buttons. They're massive, so you can find them easily by feel, with or without gloves, to keep your eyes up and scanning.

The crystal clear window isn't just big, it's noticeably taller than the glass on most enclosed pistol red dots. That helped me acquire the dot faster in between shots, giving me a real performance edge during testing.

There are only eight daylight brightness settings, which I appreciate. In a defensive situation, it's more important to find a usable setting with one or two button taps than a perfect one in four or five. If you do shoot under night vision, there are four brightness settings for that.

I know the MRS-1 is new, but I can't help but get excited about it. As I said in the video, unless the wheels totally come off, this is the enclosed optic to have.

4. Banish 9K - Best Suppressor

Quick Verdict: The Banish 9K is an excellent suppressor for any pistol, including the Walther PDP. It strikes a great balance between size and noise reduction, and it's so light that you don't need a booster. If you have a suppressor-ready PDP, this will thread directly onto the barrel. If not, you'll need a threaded barrel and suppressor-specific recoil spring assembly.

Best Suppressor
Banish 9K
Prices accurate at time of writing

Pros

  • Light enough to use without a booster
  • More compact than most suppressors
  • Great performance for the money

Cons

  • Can't be disassembled for cleaning
  • Requires a suppressor-specific recoil spring assembly

Specs

  • Decibel Rating: 26 dB
  • Caliber Rating: .380 ACP, 5.7x28, 9mm, .300 Blk
  • Material: Titanium
  • Construction: Additive construction
  • Mount: Direct thread (1/2x28)
  • Dimensions: 4.1" long x 1.3" diameter
  • Weight: 3 oz
  • Country of Origin: USA

Why We Love It

The Banish 9K from Silencer Central is my favorite pistol suppressor, and it does a fantastic job on my PDP.

This can's claim to fame is an overall weight of just under 3 ounces. That means you can mount it directly to the barrel without inducing malfunctions. I've shot with it on several pistols and with several types of ammunition with no failures to report.

The all-titanium construction is also very durable. According to Silencer Central, you can even fire full-to .300 Blk through the 9K.

Cleaning will require a good, long soak or an ultrasonic cleaner, because the 9K doesn't come apart like some Banish suppressors. I recommend weighing it every once in a while to monitor carbon buildup.

There are definitely quieter 9mm suppressors out there; this one is built to be compact. While it's not something I'd carry concealed, it is very maneuverable on the range. I'd feel totally comfortable about using this in a home defense role.

5. XS Sights R3D 2.0 - Best Sights

Quick Verdict: The XS Sights R3D 2.0 suppressor-height night sights are the best upgrade available for your Walther PDP'S factory sights. A set of three tritium vials keep them visible at all times, in all lighting conditions. They're tall enough that you can use them with a suppressor and co-witness with even the chunkiest red dots. Build quality is top-notch, too. Installation can be a little tedious, but it's an easy DIY project with a sight pusher and a Glock front sight tool.

  • Finish: Black nitride
  • Inlays: Tritium
  • Holster Compatibility: Standard
  • Country of Origin: USA

Why We Love It

It’s hard to find faults in the PDP, but the plastic sights are its weak point. My recommendation? Swap out those ho-hum sights for a set of XS Sights R3D 2.0 suppressor-height night sights.

Scott's Walther PDP

These sights are CNC-machined from steel, not molded from plastic. They have tritium inserts that glow for decades instead of white paint. Most importantly, they’re tall enough to use with a red dot or a suppressor installed.

Installing these sights isn’t complicated, but it requires patience and attention to detail. Achieving a proper (super tight) fit means you’ll have to file the base of the rear sight to remove almost imperceptible amounts of extra material.

Walther PDP
Red dots are great, but can you still see your irons if you need them?

When shooting with irons, these make life easy. They’re quick to acquire and perfectly accurate as long as you set them up correctly. I found it easy to switch my focus from the red dot to these irons on the fly.

They're tall enough that you can aim over a suppressor, and get co-witness with thick-bottomed red dots like the RMR.

Prominent tritium vials keep these sights usable at night. I know this upgrade is fairly expensive, but I think the tactical advantage is worth it.

XS Sights RD3 2.0

I know someone takes their pistol seriously when I see a functional set of irons bracketing their red dot. Grab a set of these, a sight pusher, and a Glock front sight tool to give your PDP the sights it deserves.

6. Safariland 6354 RDSO - Best OWB Holster

Quick Verdict: The Safariland 6354 RDSO is the best duty holster I've used. It occupies a happy middle ground between conventional holsters with no active retention and Safariland's range-topping Vault series. It's a little bulky, but it's very secure and allows a very fast draw for duty use or competitive shooting. Safariland holsters are always tough, and I've actually grappled while wearing this holster with great results.

Best OWB Holster

Pros

  • Duty-grade toughness
  • Excellent retention
  • Multiple holster mounting options

Cons

  • Requires a little bit of setup
  • Works best with a duty or competition belt

Specs

  • Style: OWB
  • Material: SafariLaminate
  • Retention: Automatic Locking System
  • Optic-Compatible: Yes
  • Light-Compatible: Yes
  • Country of Origin: USA

Why We Love It

Safariland arguably makes the best duty holsters money can buy, and there are a few models that support the PDP. My favorite is the Safariland 6354 RDSO.

Safariland 6354 RDSO PDP
This retention mechanism won’t slow you down.

This holster strikes an excellent balance between retention and speed. The Automatic Locking System (ALS) pins the pistol in place until you release the thumb lever. Run, crawl, jump, and climb as much as you want – that pistol’s going nowhere.

Activating the release lever with your thumb is so intuitive that it’ll become part of your natural draw stroke in no time.

You can pick from several colors, including Cordura nylon wraps. All of them come with suede lining to protect your PDP’s finish.

Safariland invited me out to Full Spectrum Warrior a few years ago to see what the brand’s retention levels are all about. I grappled with other attendees who were actively trying to rip my plastic training pistol out of it, engaged targets from inside and around vehicles, and ran an obstacle course with the 6354 RDSO. It didn’t miss a beat.

As an all-around OWB duty holster, it doesn’t get better than this.

7. BlackPoint Tactical FO3 - Best IWB Holster

Quick Verdict: The Walther PDP is a thick pistol, but the slim BlackPoint Tactical FO3 conceals it surprisingly well. Build quality is excellent, and there are no better belt clips than these from Discreet Carry Concepts. Comfort is a strong point, thanks to the leather wing and high sweat guard. All FO3 holsters are compatible with red dots, and light-bearing models are available.

Why We Love It

The Walther PDP makes an excellent concealed carry pistol, and the BlackPoint Tactical FO3 is my preferred IWB holster for the blocky PDP.

Scott's Walther PDP 2

There are a few things that set the FO3 apart.

The belt clips are extremely aggressive; your clothing will shred to pieces before they let go. The rear clip is mounted on a leather wing that helps the holster bend around the contour of your waistline.

The Kydex and simple design keep the FO3 nice and thin, which I appreciate because the PDP is thick enough on its own.

The FO3 is designed to be comfortable at the strong-side position (hence the flexible wing), but you can certainly use it for appendix carry, as well.

The main drawback for some people will be the lack of a magazine carrier, but there are lots of ways to solve that problem.

I’ve used the FO3 while hiking, snowshoeing, and camping. I wouldn’t go so far as to say the PDP disappeared on my waist, but it certainly didn’t slow me down. This is a great way to carry your PDP, especially if it’s a full-size pistol with a light.

8. Walther DPT - Best Trigger

Quick Verdict: Walther's standard PDP trigger is great, but you can reach a new level of striker-fire refinement with the Walther Dynamic Performance Trigger. The pull and reset are shorter, the break is sharper, and the flat-faced shoe provides a consistent feel every time. Unlike a lot of upgraded triggers, this one isn't too light for duty use. It's sophisticated but not twitchy -- perfect for the discerning shooter.

Why We Love It

Yes, the PDP already has one of the best factory triggers in the striker-fire market, but the enhanced Dynamic Performance Trigger is on another level. I challenge you to find a better OEM striker-fire trigger.

Walther_PDP Match_PPT_2
You don’t have to buy a PDP Match to get the DPT; Walther sells this awesome trigger individually.

For Less than $200, you can upgrade your PDP to have the same trigger found in the top-shelf PDP Pro SD and PDP Match.

In a word, the DPT is superb. Travel is minimal, reset delivers a strong tactical and audible click, and the flat face adds a touch of class.

Trigger feel is subjective, but I (along with trigger snobs everywhere) think it makes the PDP even better to shoot.

I raved about this trigger when I reviewed the PDP Match, I love it on the PDP Pro SD, and I’d happily buy one and install it myself if I had to.

The fact that it's a Walther factory component adds a nice layer of reassurance from a warranty and legal standpoint.

Here's a video from Walther to help with the installation. It's not complicated, but there are several roll pins and a fiddly little slide lock spring involved.

9. ZR Tactical Solutions +4 Basepad - Best Magazine Extension

Quick Verdict: Extra magazine capacity (where allowed) is always welcome, and these ZR Tactical Solutions +4 base pads are my pick for the Walther PDP. They're carved from solid aluminum, with a durable anodized finish that still looks great after countless training sessions. Installation is easy and straightforward; just be careful with those delicate set screws.

  • Capacity increase varies by model of PDP

Specs

  • Material: Billet aluminum
  • Finish: Anodized
  • Capacity: +4
  • Country of Origin: USA

Why We Love It

These ZR Tactical Solutions magazine base pads increase your full-size PDP’s capacity by four rounds (ZRTS also makes magazine extensions for compact PDP). If 18 rounds is good, 22 must be better, right?

ZR Tactical Basepads
Want to make your PDP better? Feed it more ammo!

They’re machined from billet aluminum and finished in brown, black, or stonewashed for durability.

You can run into feeding issues if you increase capacity without upgrading the magazine spring, so ZRTS includes springs tuned specifically for the job. I strongly encourage testing to make sure these play nicely with any other upgrades you have; for example, light recoil springs can cause feeding issues with fully stuffed magazines.

Installation is easy. Pop out the factory base pad and spring, insert the new spring, slide on the extension, and lock it in place with two set screws.

The one hangup I had with these came from the factory follower. It’s made from molded plastic, and there are rough edges that can get snagged when the magazine is almost full. I pulled the follower out and filed the edges until they were smooth – problem solved.

The PDP is a beefy of a pistol as it is. An extended magazine protruding from the grip doesn’t have any drawbacks as far as I’m concerned, and I appreciate the extra capacity.

And don’t worry; you can buy those teeny set screws separately if you lose one.

10. ZR Tactical Solutions Ultra Mass Guide Rod - Best Guide Rod

Quick Verdict: The ZR Tactical Solutions Ultra Mass Guide Rod is an elegant way to tame recoil, and replacing polymer with steel is always an upgrade. Choose from three different recoil spring weights to tune your PDP exactly how you want it. The lightest option, a 15-pounder, makes the PDP shoot buttery soft, and I've been pleased with reliability -- you may just have to download you magazine by a round or two in some cases.

Pros

  • Reduces recoil
  • Three spring weights available

Cons

  • Harder to install than the factory guide rod assembly
  • May lead to ammunition sensitivities

Specs

  • Spring Weight: 15, 17, 18 lbs
  • Material: Stainless steel
  • Finish: Raw, black nitride
  • Weight: 1.6 oz

Why We Love It

The ZR Tactical Solutions Ultra Mass Guide Rod sneaks extra weight inside your pistol’s frame to keep the muzzle down, and improves reliability by replacing polymer with stainless steel.

ZR Tactical Solutions Ultra Mass Guide Rod
This guide rod is much more heavy-duty than the OEM component.

Your factory PDP guide rod assembly weighs 15 grams. This one weighs 45 grams. It also comes with your choice of spring weights: 15 pounds for general use, 17 pounds to handle increased pressure (think suppressors or +P ammunition), and 18 pounds for a factory feel.

Since it’s machined from stainless steel, it’ll endure high round counts better than the polymer guide rod your PDP came with.

The Ultra Mass Guide Rod is so thick that you don’t even need a spring keeper. Just pop it into any 4-, 4.5-, or 5-inch PDP slide (sorry, F-Series owners) and be on your way.

After installing the Ultra Mass Guide Rod and a 15-pound spring, I definitely noticed a reduction in recoil.

Unlike adding weight with a weapon light or a brass backstrap, this doesn’t change the exterior of your pistol, so there are no impacts on appearance or limitations on which holster you want to run.

No, it doesn’t make 9mm feel like .22 LR. Yes, you still have to practice good fundamentals. But staying on target and rattling off shots is noticeably easier with the extra weight and softer spring.

11. Jarvis PDP Barrel - Best Match Barrel

Quick Verdict: If you're going to extract every last bit of accuracy out of your Walther for competition purposes, this Jarvis PDP barrel is the one to have. High-end steel, precise button rifling, and a recessed crown make it a true match-grade contender. Installation is as easy as dropping it in place. You can even choose from a few colors to give your PDP some flash.

Out to 25 yards and beyond (I've reached out to 100 yards for fun), this barrel is a certified tack driver.

Just look at that feed ramp -- that's what I call a mirror finish.

A competition barrel is one of the most reliable ways to get more performance out of your PDP, and it’s even sweeter when you can add a splash of color. Performance gains are all relative, though, so hold off on this upgrade until you feel like your shooting isn't the limiting factor.

Who Should Buy Walther PDP Upgrades

I recommend upgrading your Walther PDP if you have specific goals you want to achieve, and feel that the factory components aren't ideal for your needs.

If you're setting your PDP up for duty, concealed carry, or home defense, focus on a few upgrades that can make you more effective without sacrificing reliability. Lights, optics, and extended magazine basepads are a great start.

If you're interested in competitive shooting, the PDP is a great platform! Making it even smoother with an upgraded trigger and a metal guide rod can shave fractions of a second off your split times. Again, a nice red dot will help a lot.

If money is tight, there's nothing wrong with keeping your PDP stock. It's a great pistol! Save some money and add upgrades and accessories when you have cash to burn.

FAQs

Final Thoughts

The Walther PDP is one of the pistols we recommend the most. It's accurate, reliable as a hammer, and boasts some of the best ergonomics in the business.

Don’t forget that the biggest upgrade you can make to any pistol is training with it.

If you run your PDP the way it came out of the box, more power to you. If you want to bedazzle yours with a few upgrades, these offer the most performance for your dollar.

Can you go further? Sure. Gain a competitive edge by adding a compensator and a brass backstrap on top of all these goodies. Your PDP will shoot flatter than the Kansas horizon. That just bumps into the reality of diminishing returns for most shooters.

  • Nice article. I found a used (barely used) PDP ProE Compact for a great price. Comes with nice upgrades, mine had upgraded XS sights and I added a ZR captured metal guide rod.

      Great buy, Mike!

  • I prefer my VP9 Tactical OR over my PDP. One of my grandsons will be getting my PDP when he moves to America (TX) from Maryland.



    Also, even though it’s DA/SA, I prefer my 92GTS over the PDP too.

    First of all, really helpful video about disassemble and assemble the PDP. Thank you! I just got my first PDP - E and am liking it a lot. How often would you say should someone disassemble for cleaning? Ive heard each time you shoot... thoughts? Also, how much is too much oil and too little when cleaning? Thanks again guys!

      Congrats, Sam! The PDP can handle a lot (and I mean a LOT) of shooting in between cleanings. That said, I end each range day with a thorough cleaning regardless of how much I shot. Old habits die hard, and it gives me a chance to monitor wear items and spot little problems before they turn into big problems. If I remember right, the owner's manual will show you where to apply oil. A drop in each place will do; no need to drown it. Have fun - you've got a great pistol!

    Hmm. Most of these are considered expensive. Probably more cost effective options out there.
