Crosman MK45 CO2 BB Air Pistol .177 Cal Semi-Auto Tactical Replica

The Crosman MK45 delivers realistic training and recreational shooting with authentic tactical pistol handling characteristics. This CO2-powered BB pistol replicates the weight, balance, and operation of centerfire handguns while providing safe backyard plinking capabilities.

What Makes This Different

Unlike standard air pistols, the MK45 features a blowback action that cycles the slide with each shot, creating realistic recoil simulation. The full-metal construction weighs 2.2 pounds, matching the heft of duty pistols for proper muscle memory development. Dual-stage trigger mechanism provides consistent pull weight across all 19 shots from a single CO2 cartridge.
