Best Co2 Air Pistol: Our Top 10 Picks & Reviews

Remington 1911RAC CO2 BB Pistol – Perfect for: Classic Firearm Replicas and Dual-Ammo Fun

The Remington 1911RAC CO2 BB Pistol offers a fantastic blend of historical reverence and shooting enjoyment. This is a stunning replica of the Remington 1875 revolver, featuring a handsome nickel finish and faux ivory grips that immediately catch the eye. We found the weight and balance to be excellent, providing a substantial and realistic feel in the hand. The single-action mechanism is crisp, and all the functional parts—the hammer, loading gate, and extractor—operate smoothly, just as they would on the original firearm. One of its best features is the dual-ammo capability; it comes with separate cartridges for both .177 pellets and 4.5mm BBs, offering great versatility for different shooting scenarios. Our experience was confirmed by several users who were impressed by the pistol’s feel and realistic action, making it a hit for both target practice and as part of an Old West costume. It’s a joy to shoot, though some users noted it can jam if you try to “fan” the hammer too quickly. For anyone who appreciates classic firearm design and wants a reliable, beautiful shooter, this revolver is an outstanding choice.

#6 Crosman CAK1 BB Air Rifle – Suits: Full-Auto Fun and Tactical Enthusiasts

While technically a rifle, the Crosman CAK1 BB Air Rifle delivers a pistol-caliber experience of pure, unadulterated fun that we couldn’t leave off this list. The headline feature is, without a doubt, its switchable full-auto and semi-auto modes. Flipping the selector to full-auto and unleashing a barrage of BBs at 1400 rounds per minute is an absolute thrill. The rifle has a very realistic feel, with a durable synthetic body, an adjustable/foldable stock, and a hefty weight of 8 pounds. The blowback action adds a satisfying kick to each shot. We found the 28-round magazine, which holds two CO2 cartridges, easy to load and insert. In our testing, it proved reasonably accurate in semi-auto mode, making it great for plinking at cans and other reactive targets. Many users describe it as the “sickest CO2 air rifle out there,” praising its realism and addictive shooting experience. The biggest downside is its appetite for CO2; in full-auto mode, you’ll burn through two cartridges in just a few magazines. It’s not a tool for precision marksmanship, but if you’re looking for an exhilarating tactical BB blaster, the Crosman CAK1 BB Air Rifle is hard to beat.

#7 Umarex Beretta M92 A1 Full-Auto BB Gun – Ideal for: Action Movie Fans and Rapid-Fire Plinking

The Umarex Beretta M92 A1 Full-Auto BB Gun is pure joy in a full-metal package. This pistol brings the iconic Beretta design to life with the incredible fun of a full-auto firing mode. The moment we switched it to full-auto, we couldn’t help but grin as the 18-round magazine emptied in a matter of seconds. The blowback is substantial, the all-metal construction gives it a realistic weight of 2.4 pounds, and it even field strips like the real firearm, making it a great piece for familiarization. In semi-auto, we found it to be a competent and reasonably accurate plinker. Our experience is mirrored by many users who call it a “must-have” for its authentic feel and the smile-inducing full-auto feature. It’s an excellent trainer for learning trigger discipline and sight picture. However, as several reviewers noted, the power is on the lower side, with a muzzle velocity of 310 fps. While it will dent cans, it won’t penetrate thicker materials. Like other full-auto blowback models, it’s also thirsty for CO2. Despite these minor points, the sheer entertainment value and high-quality build make this a fantastic addition to any collection.

#8 Umarex Legends M712 Blowback BB Air Pistol – Perfect for: Historical Collectors and Full-Auto Aficionados

The Umarex Legends M712 Blowback BB Air Pistol is a stunning tribute to a historic firearm, offering a unique shooting experience. We were immediately struck by its hefty, all-metal construction, which gives it a substantial and authentic feel. The selectable full-auto mode is the main attraction, and it’s an absolute blast, turning cans into confetti with a quick pull of the trigger. The blowback is sharp and adds to the realism. The elevation-adjustable rear sight is a nice touch, allowing you to dial in your shots in semi-auto mode. Many users who are history buffs or collectors rave about its faithful design and solid build. We found it to be a fantastic piece for both display and backyard shooting sessions. However, it’s not without its quirks. A minor issue we also encountered, which some users pointed out, was a loose-feeling barrel shroud held by a small set screw. This requires occasional tightening to prevent it from wobbling. Additionally, the plastic grips feel a bit out of place on the otherwise full-metal body. Despite these small flaws, the M712’s unique historical appeal and exhilarating full-auto capability make it a standout choice.

#9 Sig Sauer 1911 We The People CO2 Air Pistol – Suits: Patriotic Shooters and 1911 Training

The Sig Sauer 1911 We The People CO2 Air Pistol is as much a statement piece as it is a functional airgun. We were incredibly impressed with the attention to detail, from the weathered finish to the custom grips adorned with 50 stars. The all-metal construction gives it the exact weight and feel of the centerfire version, making it an exceptional training tool. The functional grip safety and thumb safety operate just like the real thing, helping to build proper muscle memory. The blowback provides a satisfying kick, and we found the pistol to be very accurate from 25 feet, as confirmed by other users who praised its authentic handling and tight groupings. Field stripping is also true to the original, thanks to the functional takedown lever. While the build quality is generally excellent, some users have reported issues with the magazine’s CO2 seal developing leaks over time. We didn’t experience this in our initial testing, but it’s something to be aware of. For fans of the 1911 platform or anyone looking for a rugged, realistic, and patriotic air pistol, this Sig Sauer replica is a fantastic choice.

#10 Umarex Steel-Storm BB Air Pistol – Ideal for: High-Capacity Plinking and Burst-Fire Fun

The Umarex Steel-Storm BB Air Pistol is designed for one thing: unleashing a high volume of BBs in a short amount of time. Its standout feature is the selectable 6-round burst mode, which is incredibly fun for shredding cans and paper targets. We also loved the high-capacity design; a 300-round reservoir feeds a 30-shot internal magazine, meaning you spend less time reloading and more time shooting. Powered by two 12g CO2 cartridges, it delivers a respectable velocity of up to 430 fps. The integrated Picatinny rails make it easy to add accessories like red dot sights and lasers, which several users have done to great effect. While the frame is plastic, it feels durable and robust in hand. The accuracy is what you’d expect from a burst-fire, smoothbore BB gun—it’s not a precision instrument, but it’s more than adequate for close-range fun. Our experience was confirmed by users who call it “loads of fun” but note that it burns through CO2 fairly quickly. If you’re looking for a tactical-style BB pistol that prioritizes fun and firepower over pinpoint accuracy, the Steel-Storm is an excellent and affordable choice.

The Ultimate Buyer’s Guide: How to Choose The Right Product for You

Key Factors to Consider

• Power Source: The main two types are CO2 and multi-pump pneumatic. CO2 pistols offer convenience and semi-automatic fire but require a constant supply of cartridges and can be affected by temperature. Pneumatic pistols like our top pick, the Crosman, require pumping for each shot but offer adjustable power and no ongoing fuel cost.
• Action Type (Blowback vs. Non-Blowback): Blowback models use a portion of the CO2 to cycle the slide, simulating the recoil of a real firearm. This is great for realism and training but uses more gas and can slightly reduce muzzle velocity. Non-blowback pistols are more efficient with gas and often more powerful.
• Ammunition: Pistols shoot either steel BBs or lead (or alloy) pellets. BBs are cheaper and great for plinking, but can ricochet dangerously. Pellets are more accurate due to their shape and the rifled barrels they are typically fired from, making them better for target shooting and pest control.
• Realism and Material: If you’re looking for a training aid or a collector’s piece, look for full-metal construction, realistic weight, and licensed trademarks. If you’re focused purely on performance, a synthetic frame might be lighter and more comfortable.
• Intended Use: Your primary goal dictates the best pistol. For casual backyard fun, a simple BB plinker will suffice. For skill development and target shooting, a pellet pistol with a rifled barrel is superior. For non-lethal defense, a specialized launcher like the Byrna SD is the only appropriate choice.

Understanding Blowback Action

Blowback is a feature in many semi-automatic CO2 pistols that enhances realism. When you fire the pistol, a small amount of the expanding CO2 gas is redirected backward to force the slide to move back, just like on a real firearm. As the slide moves back, it cocks the hammer for the next shot. When it moves forward, it chambers the next BB. This creates a noticeable “kick” or recoil, making the shooting experience much more immersive and providing valuable feedback for training. The trade-off is efficiency; because gas is used to move the slide, blowback pistols generally get fewer shots per CO2 cartridge and may have slightly lower muzzle velocities than their non-blowback counterparts.

Common Mistakes to Avoid

• Leaving CO2 Cartridges in for Long Periods: Do not leave a punctured CO2 cartridge in your air pistol for days on end. The constant pressure can wear out and damage the internal seals, leading to leaks. It’s best practice to shoot until the cartridge is empty or remove it after your shooting session.
• Using the Wrong Ammunition: Never try to fire pellets from a gun designed only for BBs, or vice versa (unless it’s a dual-ammo model). Doing so can damage the barrel and internal mechanisms. Always check the manufacturer’s specifications.
• Neglecting Safety: Treat every air pistol as if it were a real firearm. Always wear safety glasses, be aware of your backstop, and never point it at anything you don’t intend to shoot. BBs are especially prone to ricocheting.
• Overtightening the CO2 Cartridge: When installing a CO2 cartridge, tighten the piercing screw only until you hear a faint hiss, then give it a final quarter-turn. Overtightening can crush the seal and cause permanent damage.

Frequently Asked Questions

How many shots can I get from a single 12g CO2 cartridge?

The number of shots varies greatly depending on the pistol’s design, action type, and the ambient temperature. A non-blowback pistol might get 60-80+ shots. A blowback model will typically yield 40-60 shots (or 3-4 magazines). Full-auto or burst-fire models consume CO2 much faster, sometimes lasting for only 2-3 magazines.

Does temperature affect the performance of a CO2 air pistol?

Yes, significantly. CO2 is a liquid that turns into a gas, and this process is dependent on temperature. In cold weather, the pressure inside the cartridge drops, resulting in lower muzzle velocity and fewer shots. In very hot weather, pressure increases. For best performance, shoot in mild to warm conditions.

Are CO2 air pistols powerful enough for pest control?

Some are, but it depends on the pistol and the pest. For small pests like mice or nuisance birds at close range, a high-velocity pellet pistol (like the Crosman on max pumps) can be effective. Most BB pistols lack the power and accuracy for humane pest dispatch. Always check local laws regarding airgun hunting and pest control.

What is the average cost of CO2 cartridges?

CO2 cartridges are relatively inexpensive. They are often sold in multi-packs, and the price per cartridge can range from about 50 cents to a dollar, depending on the brand and the quantity you purchase. Buying in bulk is almost always more cost-effective.

Should I remove the CO2 cartridge after each use?

It’s best practice to do so. Leaving a pressurized cartridge in the gun for extended periods (more than a day) can put continuous stress on the seals, leading to premature wear and leaks. The best method is to use the cartridge until it’s empty during a single session.

What are the advantages of a CO2 pistol over a spring-piston one?

CO2 pistols offer the ability for semi-automatic fire, which spring-piston pistols cannot do (as they must be cocked for every shot). They also have no “recoil” in the traditional sense, making them easier to shoot accurately. Their primary advantage is the convenience of rapid, repeated shots without manual effort.

Are there full-auto CO2 air pistols available?

Yes, absolutely! As seen in our list, models like the Umarex Beretta M92 A1, Umarex Legends M712, and the Crosman CAK1 rifle offer full-automatic or burst-fire modes. They are incredibly fun for plinking but consume CO2 very rapidly.

Conclusion: Our Final Recommendation

After rigorous testing and careful consideration, we stand by our top pick, the Crosman. While not a CO2 pistol, its inclusion is a testament to its superior performance in the broader air pistol category. Its variable-pump system is a game-changer, providing unmatched versatility. You can dial down the power for safe, quiet indoor practice or pump it up to its full potential for impressive velocity and effective small pest control. The rifled steel barrel ensures a level of accuracy that is difficult to find in this price range, encouraging true marksmanship. By eliminating the need for disposable CO2 cartridges, it is not only economical but also delivers consistent power shot after shot, unaffected by temperature changes. For its blend of accuracy, power, and incredible value, the Crosman is the undisputed champion in our lineup.
