[Tested] Smith & Wesson M&P Shield X Review: Best Shield Yet?

Yeah, I get it; do we really need another micro-compact style 9mm? Heck, does Smith & Wesson need another? They have the Shield Plus, the CSX, and the Equalizer.

Need might be a strong word, but if you are just entering the market, you are likely struggling to find the right one. I cannot tell you which is the best option, but I can show you how the Smith & Wesson M&P Shield X handles after putting it through its paces. 

Follow along as I blaze through 500 rounds of ammo, multiple drills, and a little Steel Challenge practice.

S&W Shield X: The Backstory

Smith & Wesson introduced the M&P 9 Shield in 2012, and it was a massive success. In 2012, these things were tough to get your hands on, and would often sell for well over MSRP. The Shield was not the first single-stack 9mm but it was the gun that kicked the entire genre into four-wheel drive.

Fast forward, and the Sig Sauer P365 killed the idea of the single-stack 9mm. If you could have a gun that is basically the same size or even smaller than a single-stack but with more ammo, why wouldn’t you? 

In 2021, S&W released the Shield Plus, which introduced one of the new stack-and-a-half magazines.

Now, the Shield X is revamping the Shield series again. The Shield X is more akin to the Sig Sauer P365XL or Glock 48 than a nearly pocket-sized 9mm. It aims to provide a slightly shorter compact pistol to compete in this genre of supposed Glock 19 killers.

Range Testing the Shield X: Accuracy & Reliability Analysis

I dropped a Swampfox Sentinel 2 on the S&W Shield X and got a great accuracy measurement while zeroing. I zeroed at 15 yards in an offhand shooting position, and observed groups that were often smaller than 3 inches and never larger than 3 inches. My best was around 2.8 inches, measured with a tape measure.

After zeroing, I fired the Shield X at 10 yards and could punch the X out of a B8 with traditional slow fire. The trigger is surprisingly nice and provides a crisp trigger pull that is light and smooth. The wall is noticeable but easy to overcome. It is a flat-faced design, which I am partial to.

At 25 yards, I had no problems hitting a 10-inch gong. At 50 yards, making a steel IPSC target ding was easy. The red dot does a lot of the work as long as I do not mess up the input section. 

Admittedly, sometimes I did mess that up. Compared to larger guns, I am not getting the same speed and accuracy. When I fired Bill Drills, the rounds tended to look a bit like a shotgun pattern in the target’s A-zone. With a Staccato or even a Glock 17, it is a distinctly tight group.

My 9mm ammo of choice was the less-than-stellar Monarch steel-cased ammo. It is cheap and goes bang, but it still shows some inconsistency. However, it was not enough to throw the Shield X off target. For a small gun, it is quite accurate.

Ergonomics: Fit & Feel

The grip is svelte and thin. The aggressive M&P-style texture sticks nicely to your hand. It helps keep the gun from moving with a decent grip. The grip allows for a nice, high hold on the gun with a pronounced beavertail. While the Bodyguard 2.0 left me bloodied due to slide bite, that was not an issue with the Shield X. I had zero slide bite to report.

The grip is long enough to establish a solid hold on the gun. There is no hanging pinky to deal with. A good grip helps with control and accuracy. The gun is easy to shoot rapidly, and I shot a stage of Smoke and Hope in 3.05 seconds.

The flat trigger is easy to reach and provides excellent control. It is not match light, but it is not heavy enough to make you shift any portion of your grip to pull. The magazine release is easy to reach, and the magazines drop free without drama.

The slide serrations grip back when you grab them. They are deep and aggressive, which makes it easy to grip and rip. 

That is good, because the slide release is so small and stiff that I relied solely on the slingshot method while reloading. 

After swapping my mental map of a reload, I was able to jam more ammo in quite quickly and get the gun back into the fight without issue.

Improvements I’d Like To See

The biggest issue I have with the Shield X is the slide release. If they added a shelf and extended it slightly, it would be so much better. This is not a micro-sized gun, so why include a micro-sized slide release?

I would have also preferred that S&W use an already established magazine. I understand this gun is a little bigger than the Shield Plus, but the CSX E-Series already has longer 15- and 17-round magazines, so there was already an option on the market.

Who Is It For?

Like the Glock 19 I’ve mentioned a few times, this gun fits the role of a do-it-all defensive pistol perfectly. It is easy to conceal carry, but also large and capable enough for home defense.

Being able to add a light goes a long way for home defense. The capacity keeps it modern and relevant in the home defense discussion. Like most S&W Shield entries, it is an affordable firearm that will not break the bank, either.

By the Numbers

Reliability: 5/5 

Swallowed 500 rounds of the cheapest ammo available without a hiccup.

Ergonomics: 4.5/5 

Fantastic high grip and texture; only held back by the tiny slide release.

Accuracy: 4/5 

It is not a Staccato, but for its size and class, it is above average in the accuracy department – especially with a red dot.

Customization: 3/5 

You can add an optic or light, but there isn’t a massive aftermarket for this gun yet.

Value: 4/5 

While not the cheapest in its class, it is a great value overall.

Upgrades & Accessories

A red dot is a big upgrade to any pistol, especially one you plan on using in a defensive role. My optic of choice for this article was the appropriately priced Swampfox Sentinel II.

If something goes bump in the night, you’re going to need a pistol light. Since the Shield X now has an accessory rail, I recommend adding a Streamlight TLR-7 Sub. It’s perfectly sized for this kind of pistol, and the price is affordable without sacrificing quality.

Here’s the very similar Streamlight TLR-7X in action.

How I tested the Smith & Wesson M&P Shield X

Like all Pew Pew Tactical pistol reviews, this one included 500 rounds of ammunition. I spread that across accuracy testing at distances ranging from 10 to 50 yards, pistol drills, and training for the Steel Challenge competition series.

While testing, I looked for other things this pistol does well, including ergonomics and availability of aftermarket support.

Final Verdict on the Smith & Wesson M&P Shield X

The Shield X successfully crossed the bridge between a micro-compact and a more traditional compact pistol. It offers modern features, duty-ready capacity, and a platform that is accurate and controllable enough for the modern market.

It is thinner than the Glock 19 by a large margin. If you do not mind the new magazine platform and the tiny slide release, it will serve you well.
