The combination of a unique striker-firing system with an enhanced HK light pull trigger gives the VP40 a trigger quality unequaled in any production striker-fired handgun. The VP40 trigger has a short, light take-up with a solid, single action type break followed by a short positive reset. The VP40 uses HK’s ergonomic handgun grip design that includes three interchangeable backstraps and six side panels, accommodating all hand sizes. Molded finger grooves in the front of the pistol’s grip also instinctively position an operator’s hand for optimal shooting. HK’s patented charging supports-simple components that are mounted on each side of the rear of the slide-provide better gripping leverage for racking the slide rearward. The charging supports speed reloading and make operating the VP40 easier for shooters with reduced hand strength. The VP40 has an extended Picatinny MIL-STD-1913 rail molded into its polymer frame for mounting lights and accessories. HK’s famous cold hammer-forged barrel, made from cannon grade steel, ensures long service life. All controls are completely ambidextrous.
