The H&K VP9 was overall a very impressive and new handgun. Still, many users found the paddle-style magazine release unusual, so HK offered a VP9-B variation with a button release preferred by American shooters. While most of the renowned VP9 series have the European style paddle magazine release, the VP9-B utilized a "standard" push-button magazine release. Apart from that feature, the VP9-B is a polymer-framed pistol that uses a striker-fired trigger mechanism, a modified Browning short recoil operating system, and a best-in-class trigger that surpasses those found on competitors. Weighing at 25.56 oz empty, the HK VP9-B is a full-size handgun equipped with a 4.1" barrel and fed from a magazine's capacity of 15 or 17 rounds, depending on the model year. The HK VP9-B Semi-Auto Pistol has an ergonomic, adjustable grip that includes three backstraps and six side panels, allowing users to change up to 27 differing configurations.
