The HK45 Compact uses a slim-line grip profile, otherwise is nearly identical in features to the full-size HK45. The HK45 Compact uses an HK proprietary O-ring barrel for precise barrel-to-slide lockup and optimal accuracy. Capable of firing standard .45 ACP ball through +P ammunition, the HK45 Compact has an 8rd magazine capacity but can also use 10rd magazines, including those designed for the full-size HK45. The HK45C uses a control lever frame mounted and is quickly accessible, it has a positive stop and returns to the “fire” position after decocking; the control lever function of the HK45C can be switched from the left to the right side of the pistol to accommodate left-handed shooters (additional parts required), left and right mounted control levers provide safety and/or decocking functions as required and can be fitted to the pistol simply by changing parts. For true ambidextrous use, a control lever can also be mounted on both sides of the pistol if required. Includes an extra backstrap for a custom fit for each shooter’s hand and two 8rd magazines.
