H&K USP pistols for sale at Omaha Outdoors are still a force to be reckoned with decades after introduction, widely admired for their reliability and accuracy. Heckler and Koch made the very first polymer frame production handgun, the VP70Z, over a decade before the concept even began to take off anywhere else, but it wasn’t until the introduction of the USP that the company made significant headway in the law enforcement pistol market. USP stands for Universal Self-loading Pistol, and with so many options and variants of the USP platform, the “Universal” part has definitely proven itself to be true. From the HK USP Expert 9mm to the H&K USP45 Compact to the USP9 Tactical, whether you want a concealed carry pistol or a duty gun or a dedicated suppressor platform, the HK USP still deserves consideration despite all the competition from pistols both inside and outside HK. USP calibers include 9mm, 40 S&W and 45 ACP, and available variants allow for DAO, DA / SA, decocker/safety lever, safety lever only, decocker lever only, or no lever at all, with the lever (DA / SA only), when supplied, available for the left or right side of the frame.
