10 Best Co2 Pistols 2026 in the United States

The ASG Dan Wesson 6" Airgun is a visually striking CO2-powered BB gun designed for enthusiasts. Its standout feature is the elegant chrome finish, complete with authentic markings and a unique serial number, which adds a touch of realism and collectability. The gun is made from durable metal with a comfortable ABS plastic grip, ensuring a solid and ergonomic feel when handling it. This revolver uses a double-action trigger and has an adjustable rear sight, providing good accuracy and a realistic shooting experience.

Loading the 12g CO2 cartridge is straightforward, thanks to the easy-access grip design. The gun comes with six cartridges, each holding one 4.5mm BB, a speed-loader, and an attachable rail, making it a comprehensive package for any airgun enthusiast. In terms of performance, it delivers a velocity of 426 fps, which is relatively powerful for a BB gun and suitable for target practice or casual shooting.

However, it has a limited magazine capacity of only six rounds, which might require frequent reloading during extended shooting sessions. Additionally, while the plastic grip is ergonomic, some users might prefer a full metal construction for added durability. This airgun pistol is best suited for those who appreciate detailed design, enjoy realistic action, and are looking for a powerful yet manageable BB gun for practice and recreational use.

The T4E New Walther PPQ M2 (GEN2) is a semi-automatic CO2-powered paintball pistol designed for realistic handling and moderate performance. It shoots .43 caliber paintballs, rubber balls, or dust balls, which are fairly large and deliver a satisfying impact suitable for training or casual target practice. The blowback action provides a realistic slide movement, enhancing the shooting experience and mimicking a real handgun’s recoil. Its metal slide and barrel add durability and a solid feel, making it a sturdy pistol that won’t feel cheap or flimsy.

The magazine holds 8 rounds, which means frequent reloading during extended sessions. This pistol weighs about 1.2 pounds and measures just under 12 inches long, making it manageable and comfortable to handle without being bulky. The tan and black finish suits those looking for a tactical look. The sights are likely standard or basic fixed sights, which could limit precision shooting for users seeking higher accuracy.

This pistol is well-suited for beginners or those wanting a realistic, solid-feeling training pistol rather than a high-capacity or highly customizable paintball marker. Its moderate magazine size and fixed sights make it less ideal for longer playtime or competitive accuracy.

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.
