The HK45 was developed as the evolution of the USP45 and includes several operator inspired enhancements including interchangeable backstraps, a picatinny rail, improved ergonomics, and ambidextrous controls.

The HK45 uses an HK proprietary O-ring barrel for precise barrel-to-slide lockup and optimal accuracy. HK45 barrels are made using the famous HK cold-hammer forging process for superior performance. The HK45 uses a polygonal bore, which effectively seals propellant gases behind the bullet, which produces more consistency and velocity for each shot fired, unlike regular rifling which allows some leakage of propellant gases. The HK45 utilizes HK's unique internal mechanical recoil reduction system to reduce felt recoil by as much as 30%, allowing the shooter more control during rapid fire and increasing service life.

The grip resembles the extremely ergonomic grips found on the P30 and P2000 series of HK pistols. An additional backstrap and rough texturing ensures that hands of all sizes can manipulate and control the firearm with efficiency, effectiveness, and optimal comfort. This pistol is fully ambidextrous other than the fire control lever, but that can be switched over to the right side for left handed use (additional parts required).

Extensively tested and operationally proven, the HK45 Series is a new paradigm for Heckler & Koch handgun design and is currently being assembled from U.S. and German made components at HK’s American manufacturing facility in Newington, New Hampshire.
