In development for more than four years, the VP9SK is Heckler & Koch's latest compact handgun and part of the first striker fired HK line of firearms since the renowned P7 series pistols were introduced in the 1980s. the VP9SK has all the hallmarks of the latest, state-of-the-art handgun. All of controls are completely ambidextrous. Slide releases are present on both sides of the frame and the magazine release can be easily activated by left- or right-handed shooters. The VP9SK uses HK's ergonomic handgun grip design that includes three changeable backstraps and six side panels, accommodating all hand sizes. As well as, molded finger grooves in the front of the pistol's grip that instinctively position an operator's hand for optimal shooting. The VP9SK also has an extended Picatinny MIL-STD-1913 rail molded into its polymer frame for mounting lights and accessories. The rail has been tested and certified to handle mounted accessories up to 5.6 ounces. The VP9/40-B offers a new US-style reversible push button and utilizes the same magazines as the other VP9/40 Series. The new push-button style mag release option from HK means the VP doesn’t just fit your hand, it fits your shooting style as well.
