The VP9 uses HK's ergonomic handgun grip design that includes three changeable backstraps and six side panels. Molded finger grooves in the front of the pistol's grip also instinctively position an operator's hand for optimal shooting. All controls are completely ambidextrous, slide releases are present on both sides of the frame and magazine release can be easily activated by left or right handed shooters. Pistol features an extended Picatinny MIL-STD 1913 rail molded into its polymer frame for mounting lights and accessories. The VP9 uses the proven P30 steel magazine. The trigger has a consistent pre-travel pull with a positive wall/crisp break. Shooter has a less than noticeable pre-travel pull until the trigger reaches the engagement point of the fire control parts prior to trigger break. This model ships with two 17-round magazines and and features a slide milled to accept popular red dot sights (not included).
