Our HK45 replica CO2 pistol doesn't have any recoil, but that's actually a plus. A recoiling CO2 gun gets fewer shots per cartridge so you'll save some money right there. Because it's not a very heavy CO2 pistol, just about everyone in the family should be able to handle this gun. Get out the bullseye paper targets and tin cans and start having some fun! The HK45 firearm was created to re-arm the entire U.S. military with a .45-caliber handgun instead of the 9mm. And the cost of doing that is what led to the cancellation of the program. However, Hechler & Koch knew they had a winner and opted to make it available commercially. This BB pistol is a replica of the firearm.
