The HK45 was developed as a product improvement of the highly regarded USP45, first released in the 1995. The Caliber .45 ACP HK45 includes several user-inspired enhancements including changeable grip panels (backstraps), a Picatinny MIL-STD-1913 accessory rail, better ergonomics, and more ambidextrous controls.
Along with the HK45 Compact, the HK45 was developed as a possible candidate for the Joint Combat Pistol (JCP) and Combat Pistol (CP) programs administered by the U.S. military in their search for a new service handgun to replace the 9-millimeter M9. These programs were suspended before completion and no pistols were selected.
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.
Using HKs unique internal mechanical recoil reduction system reduces the recoil forces imparted to the weapon and shooter by as much as 30%, improving shooter control during rapid firing and increasing component service life. Capable of firing standard .45 ACP ball through +P ammunition, the HK45 combines the accuracy, modularity, reliability and minimum 20,000 round service life of the famed USP45 series with the improved ergonomics of the P2000 series pistols. HK45 models can be also be fitted with threaded barrels for use with muzzle mounted sound suppressors.
Each HK45 comes standard with an extra backstrap medium and small interchangeable backstraps ensure an optimal fit for most shooters hands and complement the ergonomic profile grip.
An improved USP-style control lever, a combination safety and decocking lever, is frame mounted on the HK45 and is quickly accessible. The HK45 control lever has a positive stop and returns to the fire position after decocking.
By using the modular approach to the internal components first pioneered by HK on the USP, the control lever function of the HK45 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.
Well-suited for personal defense use, the HK45 is available in, or can be converted to, a wide variety of variants that use different trigger firing modes, including double action/single action (DA/SA) and DAO (double action only). The DAO mode uses the unique Heckler & Koch LEM (Law Enforcement Modification) firing system for improved double action trigger pull.
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 HKs American manufacturing facility in Newington, New Hampshire.

The 45 ACP (45 Auto) was designed by John Browning in 1905 for his prototype semiautomatic pistol that eventually became the legendary Colt 1911, using a .452-inch bullet. Browning proposed a 200-grain bullet; U.S. Army Ordnance, smarting from reports of poor performance of the 38 Long Colt in the Philippines, increased bullet weight to 230 grains for greater stopping power...and the 45 ACP as it is today was adopted in 1911. It remains an iconic and popular handgun cartridge for personal defense and competition, and was used by the U.S. military in submachine guns (Thompson and M3) through the 1970s. Although largely replaced by the 9mm for military use and the 9mm and/or 40 S&W in the law enforcement community, the 45 ACP is still used by the U.S. military and numerous law enforcement agencies in various applications. The standard load remains a 230-grain bullet at 780 to 850 fps, but lighter, faster bullets from 165 to 200 grain, delivering a bit less recoil, are also available.
