Prepping Your PCC for Home Defense

I have a confession to make.

I think PCCs are great home defense weapons. Even though they only shoot a pistol round. They are a valid defensive weapon and have substantial benefits over other platforms.

Off the bat, a lot of people are going to dismiss that idea. The general attitude to low-recoil self-defense is an AR-15 in 5.56. With a 5.56 rifle, you get secondary wounding mechanisms, lower drywall penetration, and a common, affordable platform.

That’s all true. A 5.56 rifle is better for defensive use.

However, A 5.56 rifle can be a big, heavy platform. PCCs can be lighter and shorter without the same concussion, noise, and muzzle flash of a short barrel 5.56 pistol.

So, today we are going to dissect the defensive PCC and how to set one up for success.

Is a PCC Good for Home Defense?

PCCs aren’t perfect for defensive use, but the right option can blend the benefits of multiple platforms.

Since they are small and, therefore, fall into the large-format pistol realm, they can be extremely compact, lightweight platforms.

In a home defense situation (close quarters), smaller guns are more maneuverable. They are easier to use with one hand, and a PCC with a 5-inch barrel isn’t spouting a ton of muzzle flash and concussion.

For shooters who might lack upper-body strength, a PCC can be a better option than a rifle, handgun, or shotgun.

If you can handle a 5.56 rifle, then do so, but if not, a PCC might be the better solution.

Building Your Home Defense PCC

There are tons and tons of PCCs out there at a wide variety of price points. Most are straight blowback operated. Straight blowback guns are okay, but have excessive recoil.

When a 9mm has the same recoil as a 5.56 rifle, then some of the value of a PCC starts to dry up a bit. I do think a delayed blowback system is the better option. Roller delayed, radial delayed, and similar designs lessen the recoil to nearly nothing.

If you are using a straight blowback system, consider using a hydraulic buffer. Companies like KynShot make a hydraulic buffer that reduces recoil from straight blowback guns quite nicely. It’s expensive, but still cheaper than purchasing a delayed blowback system.

PCC Magazines

With PCCs and subguns, you have two magazine options – pistol mags, commonly Glock magazines, and dedicated SMG-type magazines. Both have their pros and cons.

Handgun magazines allow you to match your PCC to your handgun, so there’s more familiarity and less stuff lying around. If you’re using something like Glock magazines, you also get the benefit of a wide range of capacities and competitive pricing.

Pistol magazines are a reliable option, and for most civilian users, they do the job

SMG magazines, on the other hand, tend to be both double-stack and double-feed. This makes them a little shorter and easier to load to capacity.

Dedicated magazines can also accommodate a curve, which makes them more reliable when used extensively.

Additionally, the curved or straight designs allow for better ergonomics since there isn’t a dedicated slant to deal with while reloading.

The downside is that most dedicated SMG magazines are proprietary, which can increase their price and reduce availability. However, we’re seeing a trend of reducing these costs and making these mags more accessible. (For instance, Sig Sauer MPX = CZ Scorpion mags.)

PCC Lights

Defensive firearms need a weapon light.

Luckily, PCCs with modern handguards make attaching lights easy.

Accessories shouldn’t hamper the advantages of your platform. PCCs and subguns are maneuverable and lightweight, so you don’t want a giant light disrupting that. (Although it’s rad, I’m not going to suggest a Cloud Defensive OWL on an MP5 for this reason.)

A light that can throw a beam hundreds of meters is also not useful on PCCs since that’s outside the effective range of the platform. What you want is a light that fill a room to identify threats.

For this reason, stick to something like a Streamlight TL RM2 or Modlight PDw30. The Streamlight is a more affordable light but pushes 1,000 lumens and 22,000 candela.

If you’re a fan of modern high candela lights and your budget is higher than Snoop Dogg then the Modlite PDW 350 is another great option. It offers 1,350 lumens and 54,000 candela but is micro-sized and lightweight at only 4.6 ounces.

PCC Optics

In the year of our Lord 2025, iron sights are backups (if they are present at all).

A good optic is an excellent accessory for home defense, and I recommend some form of reflex sight. Reflex sights are non-magnified optics designed to provide an intuitive and easy-to-use aiming system.

Put the often simple reticle on the target and start pulling the trigger – making them the go-to option for home defense. They work in all lighting conditions, use a single focal plane, and are available at all budget levels.

The Holoson ARO and EoTech XPS2 are two of my favorites. Holosun’s ARO is a budget optic with typical features, like shake awake, a long battery life, and a bright and clear reticle. It comes with both a tall and low mount, so it can accommodate a variety of PCCs and uses the Aimpoint T1/T2 mounting platform. My ARO has held up extremely well.

The EoTech XPS2 is a holographic optic and, as such, is more expensive than red dots like the ARO. (EoTech is a favorite of SOCOM, Rangers, JSOC, etc.) Its reticle is clear and works really well for shooters with astigmatism. It can also withstand some serious abuse.

PCC Ammo

Ammo is easy, you just need a jacketed hollow point, right? Well, yes, but no. It all depends on the firearm’s barrel length.

Most pistol rounds are built around 3 to 5-inch barrels. So, if you’re using a large format pistol with a barrel that’s 5 to 8 inches, you’ll be fine with standard jacketed hollow points; but if you’re using a full-sized PCC with an 8 to 16-inch barrel, you need to pump the brakes.

Longer barrels increase velocity, and the velocity causes the hollow point to expand too early, which will limit penetration.

Penetration is absolutely necessary for a pistol round – the projectile needs to travel deep enough to reach the vitals.

If you’re using a longer barrel, a heavier grain projectile is the way to go. In general, a 147-grain jacketed hollow point will perform a bit better from those longer barrels.

Suppressors for PCCs

One of the best things about PCCs and subguns is how easy they are to suppress.

Unlike rifle systems, you can shoot subsonic rounds without having to alter your gun. Subsonic ammo is also widely available and affordable for various calibers.

Suppressing your home defense gun makes a ton of sense. Shooting indoors seemingly magnifies the sound of your shots being fired. A can cuts noise considerably and will preserve some of your hearing.

Which suppressor? That’s up to you, but I’m partial to the Spectre 9 from SilencerCo. It’s very light, very tough, and I can use it on handguns and PCCs without a problem.

Final Thoughts

The defensive pistol caliber carbine doesn’t have the same degree of effectiveness as a modern rifle round; however, the platform is where the strength of the gun lies.

PCCs are lightweight, ultra-maneuverable, and cheap to shoot, with minimal muzzle flash and suppression capabilities. If you set one up properly, you’ll be hard-pressed to be considered underarmed.
