How We Chose the Best AR-9 Pistols & Pistol Caliber Carbines

For this article we focused on AR-9s that balance accuracy, reliability, and a compact size with value and features.

Between our hands-on reviews, shooting events, and guns from our personal collections, we’ve shot thousands of rounds and spent hundreds of hours with AR-9s. For all of the recommendations listed, you'll notice hands-on gun reviews that detail our personal experience with each one.

All hands-on reviews adhere to a strict testing protocol that requires a minimum of 500 rounds through every review gun -- though many of our recommendations have upwards of a thousand or more rounds. For each gun we review, we shoot FMJ and JHP ammunition and a couple of different magazines to evaluate accuracy and reliability with various ammo and magazines.

Palmetto State Armory is a major name in budget options for a wide range of firearms. The PSA AR-9 is a solid installment in their lineup, and one of the best bang-for-the-buck starter AR-9s you can get.

Fit and finish seem a bit utilitarian, but this AR-9 will always go bang. And in the end, that's what really matters, right?

I've used them for a few PCC competitions and had a blast. PSA offers everything from complete carbines to complete lowers and complete uppers so you can build whatever you want.

However, it should be noted that most PSA AR-9s do not have Last Round Bolt Hold Open.

• Caliber: 9mm

• Weight: 7.1 lbs
• Capacity: 35+1

It's becoming increasingly difficult for manufacturers to stand out in the AR-9 game, but we were very impressed with the Daniel Defense PCC 916.

It's accurate, has comfy ergonomics, and chewed up all the ammo we fed it during our testing.

A lot of 9mm PCCs have pretty punchy recoil due to their direct blowback operating systems. That's the same setup Daniel Defense uses, but the Kynshot hydraulic buffer soaks up recoil like a sponge. This is one soft-shooting AR-9!

The PCC 916 is on the more expensive side of things, but it's an excellent firearm. Grab one and use it for fun, home defense, or competition. It'll handle it all.

Looking for something a little different? There are other Daniel Defense PCC variants, including an AR-9 pistol and a short-barreled rifle (SBR).

Specs

• Caliber: 9mm
• Barrel Length: 3.5-16"
• Overall Length: 11.8-35.25"
• Weight: 4.3-6.6 lbs
• Capacity: 20+1-35+1

The Sig Sauer MPX uses a short piston recoil system that eliminates the need for a buffer tube. The result? A compact, soft-shooting AR-9.

Several configurations are available, including a full-length PCC. The MPX platform will be familiar to anyone who's used a standard AR-15, and it has the added bonus of ambidextrous controls.

During testing, our MPX ran well and rang steel with no problem. We did have one experience where a fully-loaded magazine caused a malfunction, but that could have been a mag issue. The gun worked well outside of that. 

Overall, the Sig MPX is a good blend of features, ergonomics, and value. This might be our favorite AR-9 right now.

PSA hits our list again, this time with the Palmetto State Armory AR-V, a decently priced AR-9 pistol with a unique twist.

This platform uses PSA's proprietary AR-V and AK-V magazines, which are interchangeable with the popular CZ Scorpion EVO mags.

We found our test AR-V to be pretty reliable and accurate. The AR-V looks great with a 10.5-inch barrel and a 9-inch M-LOK handguard, too.

It has the same mag release that's on the AK-V. It takes a little bit of getting used to, but it works great once you do.

Specs

• Caliber: 9mm
• Barrel Length: 6"
• Overall Length: 22"
• Weight: 5 lbs
• Capacity: 17+1

The Angstadt Arms UDP-9 is a finely-tuned 9mm AR pistol that’s compatible with Glock magazines and aftermarket magazines for Glock pistols.

While it does have a pretty hefty price tag, there were no corners cut when making this AR-9. Plus, it's not afraid to eat cheap, steel-cased ammo.

Since the UDP-9 functions like every other standard AR-15, you don’t have to worry about getting used to new controls . From 10 to 30 yards, we found the accuracy to be on point and pretty impressive for an AR-9 this small.

Need a truck gun or something for your bug-out bag? This would be an excellent option, given its compact size and the fact that it shares magazines with Glock pistols.

If you're looking for a high-end AR-9, check out the UDP-9. We had a blast with the one we tested. You can read all about it in our Angstadt Arms UDP-9 review.

Specs

• Caliber: 10mm

• Overall Length: 23.8"
• Weight: 5.5 lbs
• Capacity: 30+1

Want to look down on all these blowback guns with an air of superiority? Check out the CMMG Banshee series.

These ARs rely on a proprietary radial delayed blowback operating system that seriously cuts down on recoil, especially during rapid fire.

Of course there are 9mm variants, but we tested their 10mm Banshee because it's one better, right?

It ran like a scalded dog in our testing, eating up that extra oomph and making 10mm ammo feel like 9mm ammo.

There are also different levels of awesomeness within the Banshee series, from the 100 to the 200 to the 300 series we tested. It comes with everything you might want already upgraded.

Plus, it looks great! Check out our hands-on CMMG Banshee review for more info.

Specs

• Caliber: 9mm

• Weight: 4.9 lbs
• Capacity: 30+1

Want another high-end PCC to consider? Then look no further than the professional-grade B&T APC9 Pro.

The Swiss-made APC9 Pro is one of the most flexible guns on this list. It can run mgazines from B&T, Glock, and Sig Sauer, depending on which lower you get.

And while the forend isn't very long, the dual, auto-folding, non-reciprocating charging handles won't get in your way. This helps keep the overall profile very compact and snag-resistant.

The controls are a pretty familiar blend, and the APC9 Pro handles very well. Felt recoil is manageable -- maybe even tame when a suppressor is used. But don't forget the adapter because the barrel uses the European tri-lug setup.

All this capability comes at a lofty price, though. You know you want to read more about this neat little gun, so check out our hands-on B&T APC9 review!

How to Pick the Best AR-9 Pistol Caliber Carbine

Why would you want a 9mm AR in the first place? Should you get a carbine- or pistol-length AR-9? We're so glad you asked!

Why You Need an AR-9 or Pistol Caliber Carbine

It simply makes sense to have your long gun and sidearm set up for the same ammo and magazines. That's especially true if you aren't looking to expand your collection past a few firearms or are looking primarily at home defense.

Plus, we love our Glocks (read up on all the Best Glock Models) and our AR-15s (don't miss our AR-15 Buyer's Guide).

Compared to handguns, which take a lot more skill and training to shoot well, PCCs offer a longer sight radius and four points of contact (hands, shoulder, cheek) instead of two (hands).

With pistol-braced variants, you can have everything in a super maneuverable package without sacrificing much performance. Even adding a suppressor doesn't make them unwieldy.

That shorter length also allows you to add a suppressor, and since it's an AR, you'll enjoy endless upgrades.

AR-15 and AR-9 Pistol Caliber Carbine Parts Compatibility

Do you have to buy a new gun? Can you just modify an AR-15?

Most things are the same, but you'll see a big difference in lowers.

First is the ejector. The AR-9 platform uses a different magazine well to handle pistol magazines from Glock, Colt, CZ, or some other pattern.

Also, on the lower is a different magazine catch style that I actually prefer to standard AR-15s. Different manufacturers will differ slightly, but it's a larger/longer catch than you'll see on an AR-15.

On the upper, you'll have a different bolt for your specific pistol caliber that's simpler due to most guns being direct blowback. That also means no gas block or gas tube!

And, of course, a caliber-specific barrel.

And though the lower will take any mil-spec AR-15 trigger group, I'd opt for something specifically built to handle the extra recoil of the AR-9.

We've given you some of our favorite options from budget to bougie, and even there in an extra-spicy 10mm option.

If we had to choose just one, it would be the Sig MPX. Or maybe the Daniel Defense PCC 916. Ok, maybe limiting ourselves was a bad idea. Better make more room in your gun safe.
