About H&K HK45

The HK45 was designed to meet requirements set forth in the U.S. Military Joint Combat Pistol program which had the purpose of arming the U.S. Military with a .45 ACP semi-automatic pistol instead of the 9mm M9 pistol. The HK45 represents an evolutionary advancement of the Heckler & Koch USP. It is available in the same ten variants as the USP.

The HK45 is a full size model pistol, but significant effort went towards making it more ergonomic than the HK USP full-size chambered in .45 ACP by incorporating features found on the Heckler & Koch P30. These include an extended slide release, a textured ergonomic grip with finger grooves, and interchangeable backstraps to fit differently sized hands.In order to accommodate the smaller, more ergonomic grip, the HK45 has a magazine capacity of 10 rounds versus 12 rounds of the USP. The HK45 also added grip serrations on the front end of the slide, a Picatinny rail in front of the trigger guard for mounting accessories, and an O-ring polygonal barrel for increased accuracy.
