When I purchased my PX9, I didn’t have high expectations. It was really a “fun gun” purchase for the range because I didn’t have many AR platforms at the time that used Glock mags. I liked the idea of having a pistol and PCC, both in 9mm, that used the same magazine. When I found the Palmetto State Armory PX9 on sale, I thought, “Why not?”
Training is crucial, and like many of you, I enjoy it as well. But training with a 5.56 frequently gets expensive. Ammo continues to creep up in price, and I found myself finding more drills that use less ammo. After talking to another guy who trains a lot, he suggested using an AR platform in 9mm to supplement some of my training.
This was a great idea, so I found a cheap PCC and ordered it. My first impression was great, as the little AR pistol didn’t have any issues at all. It cycled ammo, was accurate, and overall, a smooth shooter. While my ammo count is not accurate down to the last bullet, I keep decent records on most of my firearms. During my last training event, I passed the 3,000-round count on the PX9, so I thought this would be a good time for a follow-up review.
Here is a quick overview of the PX9 and how it’s been doing over the past few years.
About the PX9: Palmetto State Armory’s PCC Gem
The Palmetto State Armory PX9, a pistol caliber carbine (PCC), comes in several different variations, including carbine and pistol lengths. I selected the shorter version with an 8-inch barrel and a 7-inch handguard, which has a few M-LOK slots for mounting accessories. Because of the barrel length, it’s legally an AR pistol.
The PX9 is a “budget-friendly” option but appears to be a versatile and reliable PCC. Having an AR9 is economical to shoot but also effective for a variety of purposes, from home defense to everyday training at the range. As I mentioned above, it’s built around the AR-15 platform, offering familiarity for those already accustomed to the AR style.
One of the key features of the PX9 is its compatibility with Glock-style magazines, which is why I purchased it. This is a significant advantage, as Glock magazines are widely available, durable, and reliable. This compatibility also means that many shooters who already own Glock pistols can use the same magazines for their PX9, adding a layer of convenience and cost-effectiveness. I’m not sure you can find any magazine more available today than Glock 19/17-compatible mags.
From Glock factory mags to ETS, Magpul, KCI, and others, there are endless choices when finding a magazine for this gun. I’ve used just about every brand of magazine I can get my hands on. While I like some more than others, they have all functioned great in the PX9.
Customization, Ergonomics
The PX9 uses a blowback operating system, which is typical for many PCCs. This system is straightforward and reliable and contributes to the firearm’s overall durability. I like the shorter barrel because it strikes a good balance between maneuverability and ballistic performance. Because of its caliber and length, this is obviously not a long-distance shooter, but it’s great for CQB, home defense, and even vehicle defense.
It has a somewhat thin free-floating handguard, which I like because it’s a smaller firearm. The M-LOK system provides space for attaching accessories such as lights, lasers, or foregrips, although a foregrip would require a tax stamp. Because of the length of the handguard, not all accessories from a full-size AR will fit, but you can easily mount a light or laser if desired.
The design of the PX9 has not overlooked ergonomics. The PCC features a comfortable, adjustable SB Tactical arm brace, which may or may not stay legal. Only time will tell with the arm brace battle currently in the courts. My PX9 came with a Magpul MOE grip, which I like and is comfortable. It also has internal storage, which is a big plus.
PSA used an extended mag release, which is one of my favorite features on the PX9. It’s extremely easy to push and extends out far enough for my finger to reach it easily. The only downside is it doesn’t lock open on the last round. So far, this is the only thing I’ve found lacking on the PX9. It has a manual bolt-lock but doesn’t interact with the magazines.
Practicality
As I mentioned above, I purchased this gun to supplement some of my training because of the cost of 5.56 ammo. What I realized over time, however, is this is a great addition on its own, not just a training supplement. Now, I train with it as a self-defense weapon in combination with my handgun. Most of the time, I would opt for a 5.56 or 300 blackout when a rifle is needed. But there are times when a less powerful round is ideal.
But when you want a pistol caliber, this is a great option because it runs on the same mags as your Glock handgun. You can throw on a belt or vest with multiple mags that all work in both your handgun and PCC.
For those considering the PX9 for home defense, its compact size and maneuverability are major advantages. It’s easy to handle in close quarters, and the 9mm round is effective without the over-penetration risks associated with higher calibers.
How is it holding up?
And so, it all comes down to durability in the end, right? Is a cheaper firearm going to wear out and fall apart over time? Some do, and some don’t. My experience with the PX9 is that it will hold up just great for long-term use. Aside from regular cleaning and lubrication, I haven’t needed to repair anything on the PX9.
It shoots great out to 100 yards or so and is light and easy to handle. It uses a full-size charging handle, so you can upgrade it to any type you want. I like using an extended charging handle, and I replaced the mil-spec one that came with it. I’m not sure where it came from, but I had a flash can from another project and stuck it on the PSA. I’ll probably change it out at some point, but I’m not in a hurry.
Because of the semi-AR-15 compatibility, you can upgrade the charging handle, pistol grip, safety selector, trigger, stock/brace, and bolt stop. I’ve fired all types of ammo through it over the years, from cheap range ammo to defense rounds. So far, I haven’t had any problems regardless of the ammo or magazine being used.
All the springs and pins are in great shape, the upper and lower have no sign of wear, and the barrel appears to be holding up great so far. I’ve used multiple optics on this gun over the years, and most of them have worked well with it. I’m currently using a Sig Romeo MSR red dot, which is a cheap but durable optic.
Is it worth the money?
I can easily say yes, this gun is worth every penny. Except for the lack of a last-round bolt catch, this is a great little gun. It shoots smoothly and is easy to handle. I can’t say any of my other PCC weapons shoot any better than this thing. In fact, some of my other PCC weapons have had some cycling issues with certain ammo or mags. This one eats any ammo, using any magazine.
If you don’t have a PCC yet, this is one you should try out. When combined with a budget-friendly optic, like the MSR, and some good aftermarket Glock-compatible mags, this is a reliable firearm that works for self-defense, training, and good old-fashioned range fun. You can purchase the PSA 9mm AR as a fully assembled gun or purchase the upper and lower separately. I’ve found buying them separately is often cheaper than buying a fully assembled gun. Check it out and see what your thoughts are.
