10 Best Co2 Airsoft Pistols 2026 in the United States

The Umarex GLOCK 17 Blowback .177 Caliber BB Gun Air Pistol, Gen4, is a reliable choice for airsoft enthusiasts who value realistic features. With its blowback action, it simulates the feel of firing a real firearm, making it suitable for training or recreational shooting. The full metal slide and frame ensure durability, while the realistic controls and officially licensed Glock markings add to its authenticity.

The fixed Glock-style sights make aiming straightforward, and it fits most aftermarket duty holsters, which is a plus for users looking for compatibility with existing gear. However, the FPS is relatively modest at 320, which means it might not be the best choice for users seeking high-velocity shooting. The 18-shot magazine capacity is decent, though not the highest available.

Additionally, it does not feature an adjustable hop-up system, which could affect accuracy at longer ranges. It is a solid option for those looking for realism and durability in an airsoft pistol, but it may fall short for users prioritizing speed and adjustable accuracy.

The Glock 19 Gen 5 MOS .177 Caliber BB Gun is a solid choice if you want a realistic, metal-framed CO2 airsoft pistol with good power and customization options. It shoots .177 caliber BBs at around 330 FPS, which is a respectable speed for target practice or casual plinking. The pistol features a metal build for durability and feels more authentic compared to plastic models. Its magazine holds 17 BBs and is drop-free, making reloads fairly easy.

Powered by a CO2 cartridge in the magazine, it requires CO2 refills (not included), and it’s recommended to use Umarex-brand cartridges for best performance. The highlight is the MOS (Modular Optics System) mounting, allowing users to attach various micro pistol optics, a nice bonus for those who want to customize their sights. Additionally, it has an integrated rail for mounting lights or other accessories, increasing its versatility.

This BB gun is best suited for recreational users interested in a realistic feel and some customization rather than competitive airsoft or tactical gameplay. If you want a sturdy, fairly powerful CO2 pistol with optic options, this Glock 19 Gen 5 MOS is worth considering.

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.
