Description
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.
While the gun doesn’t have any recoil, that’s actually a plus. A recoiling CO2 gun gets fewer shots per CO2 cartridge, so you’ll be saving money with every shot!
All you have to do is insert a CO2 cartridge, load the mag with 20 steel BBs, take off the safety and start pulling the trigger. It’s all-day fun shooting at bullseye targets, tin cans and more. Because it’s not a very heavy pistol, shooters of all sizes and genders should be able to handle this shootin’ machine.
