The HK45 is full-sized like the Universal Self-loading Pistol (USP), but with ergonomic styling like the P2000. The HK45 adds front end grip serrations on the slide, a Picatinny rail, and an O-ring polygonal barrel for increased accuracy and more consistent lock-up of the slide and barrel during cycling. HK's unique internal mechanical recoil reduction system reduces recoil by as much as 30%, and the polymer frame with a textured ergonomic grip allows the pistol to sit lower into the web of the hand, contributing to recoil management and greater control of the weapon. This pistol features interchangeable backstraps, night sights, and an extended ambidextrous slide release. The HK45 has ambidextrous controls, enabling the control lever to be switched from the left to the right side of the pistol (additional parts required); for true ambidextrous use, a control lever can be mounted on each side of the pistol. The HK45 has been extensively tested and operationally proven, and it is well-suited for personal defense use. This model comes with 3 magazines.

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. — Craig Boddington
