Best 300 Blackout Pistols

Let’s review the best 300 Blackout pistol contenders.

Springfield Armory Saint Pistol

If you’re looking for something lightweight and compact for close-quarter battle, small game hunting, or casual target practicing, the Springfield Armory Saint Pistol delivers. It has a 7.5” barrel and uses the 300 Blackout caliber rounds. Its overall length is 26.5”, and it weighs around 5.8lbs.

This lightweight pistol is suitable for one and two-handed shooting thanks to its SB Tactical SCX-K forearm brace – one of my favorite braces on the market.

The pistol features high-quality components, with both the lower and upper receivers made of 7075 T6 aluminum. You’ll get a forward assist for the upper, which is neat. The lower has the Accu-Tite tension system that mitigates movement and overrides misfitting. 

The muzzle comes with a faux suppressor on top, but with no sights. However, that doesn’t diminish the pistol’s overall value by much.

I find that the trigger is super smooth, providing crisp action and clean firing. It sports nickel boron coating and is a single-stage model. Also, thanks to the low recoil, the Saint is among the most accurate models out there.

The barrel features Chrome Moly Vanadium, and it’s finished in Melonite. Its twist rate Is 1:7, as well as a pistol-length gas system. Finally, Springfield opted for the M16 bolt carriers made of Carpenter 158 steel to make the pistol more robust and durable.

Pros

  • Lightweight and compact
  • Low recoil and high precision
  • High-quality trigger
  • 7075 T6 receivers
  • SBX-K brace

Cons

  • No sights

Sig Sauer MCX

I recommend this one for tactical operators out there. The Sig Sauer MCX has three-point stabilizing braces with momentary deployment, as well as neutral controls, meaning that both left- and right-handed users can shoot with no problems. That makes it a valuable ally in a dangerous situation.

The semi-automatic MCX weighs around 5.1 lbs. and has a 5.5” barrel. The overall length is mere 19.3”, which I find very handy. The pistol is also available with an 11.5” barrel if you want something more substantial.

This gas-operated pistol has a standard 30+1 round capacity with a removable magazine. It’s made in the USA and features top-shelf materials.

For example, the barrel is carbon steel, while the frame is 7075 T6 aluminum. The barrel also features nitride finish and a gas piston system on top. Its hammer forged for stabilization, sporting a 1:5 twist ratio.

Handguards are free-floating and have a mil-spec upper receiver. I also like that the upper receiver is compatible with all AR lowers that feature military specifications.

On the downside, the Sig Sauer MCX is quite expensive. Also, it’s not the best 300 Blackout pistol for beginners.

Pros

  • Compact and lightweight
  • Three-point adjustable brace
  • Mil-spec receivers
  • Carbon steel barrel
  • Ambidextrous controls

Cons

  • Not beginner-friendly
  • Expensive

Wilson Combat – AR-15 Protector Pistol

The Wilson Combat – Ar-15 Protector Pistol isn’t a cheap pistol. But it more than compensates for that with versatility and quality. The only significant difference between the Protector and the more expensive Wilson Combat models is that the Protector has forged receivers instead of the standard billet ones.

The pistol has an 11.3” barrel made of top-grade stainless steel to improve its longevity. That means that the gun is among the longer ones in its class. Fully assembled, with the brace, it measures around 30”.

Wilson Combat offers two gas systems for this model. You can choose between the 300 BLK pistol and 300 HAM’R options. That makes the gun even more versatile and adjustable. Of course, both feature top-shelf build quality.

The state-of-the-art trigger is one of my favorite features of this pistol. It is a two-stage TTU model with a 4.5-5“ pull. Wilson Combat paired it with an oversized trigger guard for increased safety. Also, recoil won’t be a problem with this model.

Another neat feature of this pistol is its adjustable brace. It’s a Tailhook Mod 2 model. The Protector also features a handguard compatible with all M-LOK models. The handguard also features a 4” accessory rail.

Pros

  • Exceptional craftsmanship
  • Low recoil
  • Fantastic two-stage trigger
  • Versatile pistol
  • Reliable

Cons

  • Expensive

PSA 8.5” Pistol-Length 300AAC Blackout

The PSA 8.5 Pistol-Length 300AAC Blackout might be the best 300 Blackout pistol on the market for beginners. I like that it’s affordable, precise, and lightweight. Also, it’s a pretty reliable pistol, which is a pleasant surprise in this price class.

The 8.5” barrel of this pistol is chrome-moly with a nitride finish. That will make cleaning after the hunt or practice a piece of cake. Also, it’s a threaded model, meaning you can use a suppressor with it.

The gas system is pistol-length, and PSA combines it with a ¾” gas block. The system has a 7” handguard on top that has a Picatinny rail. You can use the rail to mount aftermarket optics on the pistol.

The buffer tube is a Shockwave aluminum type, which is nice. That said, PSA modified it to suit the pistol, and it also has a polymer stabilizer, which makes the gun even lighter.

PSA makes the bolt carrier group of this pistol per military specifications. That means that the bolts feature Carpenter 158 steel with phosphate treatment.

Aside from beginners, I would recommend this pistol for people looking for an affordable 300 Blackout model for home defense, as it’s very precise in a close quarters situation.

The pistol doesn’t feature any sights, which is perhaps its only notable downside.

Pros

  • Affordable
  • Reliable
  • Precise
  • Beginner-friendly
  • Easy maintenance

Cons

  • No sights

Ruger AR-556 300 Blackout

I like the Ruger AR-556 300 Blackout because it’s an affordable and reliable pistol. Ruger has used all of its experience and know-how to make a quality pistol at this price point.

>>Brownells (Buy Here)<<

The model in my review sports a 10-1/2” barrel with a 1:7 twist ratio. It has a hammer-forged barrel and will, therefore, last a long time.

The neat thing about this little pistol is that it has a pistol-length gas system. That allows it to shoot both subsonic and supersonic rounds. Thanks to that, you can use this Ruger in a broad range of scenarios.

On the technical side, it has a high-quality SBA3 Brace that helps stabilize the pistol when you shoot. The free-floating handguard also helps minimize the recoil. It’s 9” long and features high-grade aluminum.

The upper receiver is made of 7075 T6 aluminum and also has a forward assist, which I find very useful. You also get a brass deflector and a handy dust cover.

Weighing around 5.8 lbs., I find this pistol light enough for most uses. However, I think that hunters and sport shooters will have the most fun with it.

Pros

  • Affordable
  • Precise
  • Well made
  • Quality materials
  • Suitable for hunting and sport shooting

Cons

  • Might not be the best solution for close-quarter combat

About the 300 Blackout Pistol

Now let’s first take a look at how to choose the one for you. There are many things to consider, though you should pay special attention to the following aspects.

The list includes the buffer tube, gas system quality and materials, ergonomics, and barrel length. Finally, you should decide whether you want to go with a mil-spec model or not.

Buffer Tube

300 Blackout pistols aren’t considered rifles because they have barrels shorter than 16”. Therefore, they can’t have a traditional stock. However, manufacturers have come up with buffer tubes to compensate for that.

A buffer tube comes out from the back of the receiver and allows you to install an arm brace later. And, you can even shoulder some models like you would a stock.

Examine the size of the buffer tube before you buy the pistol and see whether it suits you. Also, you should check what it’s made of and how well. For example, a more substantial and bigger buffer can help you if you’re experiencing too much recoil.

Buffers made of tungsten are heavy, while those made of aluminum are on the lighter end of the spectrum. Buffers can also have multiple adjustment points. Finally, some models have very short pistol-length or no tube at all.

Gas System Quality and Materials

A 300 AAC Blackout pistol has considerably less pressure than, let’s say, a 5.56 NATO. Therefore, a gas-powered system will allow you to use both subsonic and supersonic ammo with it.

Your pistol will have a pistol-length gas system installed. Because of that, the system will be under a lot of pressure. It will also over-gas your weapon, due to its size. This will result in more substantial recoil and more noise when firing.

To prevent extensive wear and tear of your pistol’s gas system, you should check the materials used for the system and its build quality. The gas system in your gun should ideally be better and feature higher quality materials than a rifle to extend its life as much as possible.

If you opt for a pistol with a low-quality gas system, you might have to replace your weapon sooner than you think. On the other hand, if money isn’t an issue, you might want to go for military-grade materials and craftsmanship. Military-grade or not, the best 300 Blackout pistol will offer excellent build quality in this section.

Ergonomics

When it comes to firearms, people often overlook ergonomics. They put it on the back burner while giving performance and price the priority.

A 300 Blackout pistol can be more inconvenient for some than a 300 Blackout rifle. That’s mostly because a rifle has a stock, unlike its shorter counterpart. That’s where the pistol arm brace comes in. In a nutshell, it’s a legal way to install a stock on your 300 Blackout pistol.

That way, you can convert your pistol into a short barrel rifle (SBR) without buying one. Moreover, you won’t have to pay the taxes associated with owning an SBR. The most significant advantage of a brace is that it will improve your precision and make your pistol a lot more comfortable to use.

Barrel Length

300 Blackout pistols are quite versatile, with barrel lengths varying from standard pistol lengths to 16”. The longer models can give your bullets more speed and more precision. On the other hand, a super-short barrel won’t be as precise or offer as much velocity.

Therefore, you should consider the range at which you want to use your 300 Blackout. If you want it for some light target practicing or short- to mid-range hunting, then you’ll be more than OK with a pistol-length barrel. Also, if you want a 300 Blackout for home defense, a pistol-length barrel will suffice.

However, if you need a reliable weapon for distances greater than 300 yards, you might want to opt for a Blackout rifle instead of a pistol.

Mil-Spec or Not?

The expression mil-spec stands for military specifications. That means that the particular firearm follows the specs prescribed by the military. Manufacturers will use dimensions and materials that the military uses if they want to put the mil-spec sticker on the weapon. Also, the gun has to have government certification to get the coveted badge.

Unfortunately, some manufacturers use the label on models that don’t use actual military specification parts or have appropriate dimensions. While it’s good-to-go with mil-spec parts, you should keep your eyes open. Research the manufacturer and find out if the label is there for marketing purposes only.

Conclusion 

To make sure you have the best 300 Blackout pistol, you should first consider your needs. Then, think about the quality and construction of the gas system. Important aspects also include the buffer tube, ergonomics, and whether the pistol features military specifications or not.

If you want something affordable, the PSA and Ruger models are your best options. If you need a high-end pistol for close quarter combat, I recommend the Springfield. The Wilson Combat model is super-versatile, while the Sig Sauer can accommodate left- and right-handed users.
