Experience gained by HK engineers with the P30 hammer-fired pistol had a direct influence on the design of the VP9, but the VP9 breaks new ground with its integration of a unique striker firing system with an enhanced HK “light pull” trigger. The net result is a pistol with custom-fit ergonomics with trigger quality unequaled in any production striker fired handgun. All controls are completely ambidextrous including HK’s patented charging supports — simple components that are mounted on each side of the rear of the slide and provide better gripping leverage for racking the slide rearward.
