10 Best Co2 Pistols 2025 in the United States

The Umarex GLOCK 17 Blowback .177 Caliber BB Gun Air Pistol, Gen3, is a well-rounded air pistol that offers a lot for both beginners and seasoned enthusiasts. Its .177 caliber is standard for air pistols, making it easy to find compatible ammunition. The pistol shoots BBs at a velocity of up to 365 fps, providing decent power for target practice and casual plinking. The 18-shot magazine capacity is quite generous, reducing the need for frequent reloading and allowing for more continuous shooting sessions.

The blowback action adds to the realism, making it a fun choice for those looking to replicate the experience of shooting a real firearm. Realistic controls and officially licensed Glock markings enhance the authenticity further. The full metal slide and drop-out metal magazine give the pistol a solid, durable feel, while the Glock-style fixed sights are reliable for aiming. However, the fixed sights might not be ideal for everyone, as some users may prefer adjustable sights for greater accuracy.

The need for CO2 cartridges, which are not included, means additional ongoing costs and preparation. This air pistol is also on the heavier side at 1.5 pounds, which may be tiring for prolonged use, but it does contribute to a more realistic shooting experience. Lastly, it fits most aftermarket duty holsters, allowing for easy transportation and storage. It is ideal for those looking for a realistic and durable CO2 pistol for target practice or as a training tool.

The Umarex Colt Peacemaker Revolver is a .177 caliber air pistol that stands out with its iconic design and historical significance. It features an all-metal frame and a realistic single-action mechanism, making it not just functional but also visually appealing. The pistol shoots steel BBs at a velocity of up to 410 feet per second (fps), which is quite respectable for its category. Users will appreciate the 6-round capacity, which includes six individual BB casings for added realism.

The CO2 power type is convenient and cost-effective, housed discreetly in the grip of the pistol. Being a replica of the famous Frontier Six-Shooter, it's perfect for history enthusiasts and collectors alike. However, the single-action mechanism means each shot requires manual cocking, which could be less convenient for some users. Additionally, the 6-round capacity may feel limiting for those looking for extended shooting sessions without frequent reloading.

The metal build, while durable, makes the pistol relatively heavy at 2.5 pounds, which might not be ideal for prolonged use. Despite these minor drawbacks, the Umarex Colt Peacemaker Revolver remains a strong choice for those seeking a blend of historical charm and modern air pistol performance.

The SIG SAUER P226 MK-25 CO2-Powered .177 Cal Semi-Auto Airgun Pellet Pistol is designed to mimic the handling and performance of its firearm counterpart, making it an appealing option for training and practice. This air pistol features a 16-round 8x2 rotary magazine, which offers ample shooting capacity for a practice session. Using CO2 as its power source, it achieves a velocity of up to 380 fps, making it suitable for target shooting.

One of the standout features is its rifled steel barrel, which contributes to the pistol's accuracy and performance. The build quality is decent, with a plastic frame and alloy steel barrel, though it may not offer the robustness of higher-end materials. The fixed white dot sights provide basic aiming assistance, though they lack the adjustability that some users might prefer.

The pistol's semi-automatic action allows for a more authentic shooting experience, and the built-in Picatinny rail offers the possibility of adding accessories like lights or lasers, enhancing its versatility. However, the frame material being plastic might not appeal to those seeking a more premium feel. The P226 MK-25 is chambered in .177 caliber, which is standard for training air pistols, ensuring compatibility with a variety of pellet options. The recommended pellet weight range of 5.0gr to 7.5gr ensures optimal performance. While it excels in providing a realistic training tool for shooters, the pistol's reliance on CO2 may not suit those looking for a more environmentally friendly option, and its fixed sights might limit precision for some shooters. For users seeking a cost-effective and realistic training pistol, the SIG SAUER P226 MK-25 is a strong contender.
