Like all H&K VP9 series of pistols, the Tactical model features a polymer frame and striker-fired mechanism. Unlike standard VP9 pistols, the Heckler & Koch VP9 Tactical comes with a 4.7" threaded barrel, thread protector, and suppressor height sights. The barrel is made using a time-tested Heckler & Koch's cold-hammer forging process and comes with a polygonal bore profile for longer service life. Heckler & Koch VP9 Tactical is a full-size pistol that comes with an extended 20-rounds magazine right out of the box. The HK VP9 Tactical is optics ready pistol featuring an enhanced HK "precise pull" trigger and an ergonomic grip design with molded finger grooves. The battle-ready HK VP9 Tactical has a precision machined slide with front and rear serrations and an integrated Picatinny MIL-STD-1913 rail for aftermarket accessories. As you would expect, H&K VP9 Tactical features a paddle magazine release mounted at the rear of the pistol's trigger guard.
