10 Best Co2 Pistols 2026 in the United States

The Beretta M 92 FS All Metal .177 Caliber Pellet Gun Air Pistol is a solid choice for air gun enthusiasts and collectors. Its all-metal construction and high-quality German craftsmanship give it a realistic feel, which is great for collectors and those who want an authentic shooting experience. The pistol shoots .177 caliber pellets at a velocity of up to 425 fps, which is decent for target practice and recreational shooting.

It's powered by 12-gram CO2 cartridges, which are easy to find, but note that CO2 cartridges are not included with the purchase. The CO2 power type ensures a semi-automatic action, making it user-friendly for quick shooting sessions. The gun features adjustable rear sights, allowing for better accuracy, and a manual safety for added security. Each magazine holds 8 rounds, and the pistol comes with two 8-shot rotary magazines, which is convenient for extended shooting without constant reloading.

Additionally, the included foam-lined plastic gun case offers good protection and portability. The magazine capacity is relatively low compared to some other CO2 pistols, which might be a consideration for users who prioritize high capacity. At 2.8 pounds, the pistol has a substantial weight, which might be cumbersome for prolonged use for some users. Despite these minor drawbacks, the Beretta M 92 FS air pistol remains a reliable and realistic option for both casual and serious air gun users.

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.

This makes it suitable for those who want a practice weapon that feels similar to a real firearm. The pistol has a full blowback metal slide and a field-strip capability, enhancing its realistic feel and maintenance training value. Its velocity reaches up to 380 fps with optimal pellets, which is quite powerful for a CO2 air pistol.

The inclusion of a metal barrel ensures durability, while the plastic frame keeps the weight manageable at 2.1 pounds. However, some may find the plastic frame less robust compared to full-metal counterparts. The sights are reflex sight-ready, and it includes an accessory rail, allowing users to customize their shooting experience with additional attachments. A key strength is its 20-round magazine, which is higher than many similar models, reducing the frequency of reloads. On the downside, the reliance on CO2 cartridges means ongoing costs and the necessity of having spare cartridges on hand. Additionally, while the air pistol has a heavy 6.25 lbs trigger weight, which might affect prolonged use. This CO2 pistol is ideal for those looking for a realistic and economical practice weapon with good customization options and a high magazine capacity, though it's important to consider the ongoing cost of CO2 cartridges.
