The Heckler & Koch HK45 .45ACP V1 OD green was developed as a replacement for the venerable USP 45 as well as potential replacement for the previous Joint Service Pistol competition the military did to try and replace the M9 Beretta. The pistol trials were ultimately canceled before completion, that just means that the civilian market reaps the benefits of access to the several new pistols, The HK45 V1 being the pick of the litter. Textured ergonomic grip is thin in the hand, holding 10rds of .45ACP and has interchangeable backstraps to fit to individual shooters hands. The Heckler & Koch HK45 uses the patented recoil reduction system to lower felt recoil by as much as 30%, even with defensive +P loads. H&K is known for their high quality barrels, and the HK45 V1 OD is no exception, hammer forged for long service life, and proprietary O-ring for positive barrel lockup for exceptional accuracy. Frame mounted safety decocker lever is an improved version of the H&K USP safety lever, and is in a natural position to activate it. 3 dot luminova sights charge in ambient light and hold a charge for low light shooting for quite some time. Like all H&K pistols, the HK45 OD green is fully ambidextrous meaning the slide stop and paddel style magazine release are left hand friendly without needing to swap parts. The OD green frame on this H&K HK45 gives it a unique look among polymer handguns.
