10 Best Co2 Airsoft Pistols 2025 in the United States

The Umarex GLOCK 17 Blowback .177 Caliber BB Gun Air Pistol, Gen3 is a solid choice for those looking for a realistic CO2 airsoft pistol. It features an 18-shot magazine, which is decent but may require frequent reloading during extended play. The blowback action adds a realistic shooting experience, making it a good option for training or simulation activities. With a shooting speed of up to 365 FPS, it offers reliable performance for target practice, though it may not be the most powerful option available.

The full metal slide and drop-out metal magazine contribute to its durability and authentic feel, which is particularly appealing for Glock enthusiasts. However, the lack of an adjustable hop-up system might limit its accuracy over longer distances. The pistol's fixed Glock-style sights and officially licensed Glock markings enhance its authenticity, and it fits most aftermarket duty holsters, adding to its versatility.

Weighing 1.5 pounds, it has a substantial feel without being overly heavy. One downside is that the CO2 cartridge is not included, so you'll need to purchase that separately. This air pistol is well-suited for those who value realism and build quality, making it a great addition for both casual shooters and serious airsoft players.

The Sig Sauer X-Five CO2 air pistol is a solid choice for those interested in realistic training or competitive shooting with airsoft pistols. Powered by a 12-gram CO2 cartridge (not included), it delivers a respectable velocity of up to 380 feet per second, which is good for target practice though slightly under the top speeds of some other CO2 pistols. The 20-round magazine capacity allows for longer shooting sessions without frequent reloads, which is convenient for both beginners and experienced users.

One of the standout features is its full metal slide and frame, giving the pistol a realistic weight and feel that mimics a real firearm, enhancing user experience and training value. The pistol also includes blowback action, adding to shooting realism by simulating slide movement with each shot. It comes equipped with front and adjustable rear sights to improve aiming accuracy, while the lack of an explicit hop-up system may be a consideration for users seeking enhanced pellet stability and range.

The build quality is solid due to the metal construction, though the pistol weighs around 3 pounds, which might feel heavy for younger or smaller users. This pistol is well suited for those who prioritize realism and decent performance in a .177 caliber semi-auto air pistol, with the understanding that CO2 cartridges must be purchased separately and that the absence of a hop-up system might influence performance preferences.

The Sig Sauer P320 M17 CO2-Powered .177 Cal Semi-Automatic Air Pistol is a solid choice for those looking for an authentic and economical way to practice shooting. With a velocity of up to 380 FPS, it provides sufficient power for airsoft activities. The magazine capacity of 20 rounds is decent, allowing for extended practice sessions without constant reloading.

This model features a full blowback metal slide, adding to the realism and making it feel more like a real firearm, which is great for training purposes. However, this also means more CO2 consumption, so users should be prepared for frequent cartridge replacements. The build material is a mix of plastic and metal; while the metal barrel ensures durability, the plastic frame may not appeal to everyone due to its lighter feel and potential for less resilience over time. The pistol includes an accessory rail (M1913), which allows for customization with various attachments.

The absence of a hop-up system might be a drawback for those looking for better accuracy and range adjustments. This air pistol is particularly well-suited for adults who want to practice shooting in a more controlled and less costly environment compared to live firearms. If you're an airsoft enthusiast or someone looking for a realistic training tool, the Sig Sauer P320 M17 is worth considering.
