The VP9 was developed by Heckler & Koch to meet the need for an ergonomically enhanced handgun. The VP9 striker fired design ensures a consistent trigger pull weight from the first shot to the last. Safety features abound on the VP9 and include a Push Button Magazine Release and a unique side mounted drop safety for the firing pin. The frame incorporates a trigger mounted safety that prevents accidental discharge if the VP9 is struck or dropped, and a disconnector ensures that the slide must be in battery for the VP9 to fire.
