Item # 55013 Style HK-2252304 UPC 723364523045 Condition New Manufacturer [HK Airguns](https://www.kygunco.com/brand/hk-airguns) Caliber .177 PELLETS ### [HK45 CO2 BB Pistol](https://www.umarexusa.com/products/hk45-co2-177-black) 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. - Metal slide - CO2-powered - Uses one 12-gram CO2 cartridge - Shoots steel BBs - 20rd drop-free BB mag - Double-action only - Fixed front and rear sights - Integral Weaver accessory rail under the barrel #### Specifications Caliber 0.177" (4.5mm) Max Velocity 400 fps Loudness 4-Medium-High Barrel Length 4.87" Overall Length 8.0" Shot Capacity 20 Barrel Smooth bore Front Sight Blade Rear Sight Fixed Scopeable No Buttplate None Suggested for Plinking/Fun Action Semiautomatic Safety Manual Powerplant CO2 Function Repeater Trigger Action Double-Action only Body Type Pistol Weight 1.4 lbs ** WARNING: This product contains chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm.
