Hk 50217891 9Mm/40 S&W/45 Acp H&K Usp Black Polymer

The H&K USP ambidextrous safety lever kit brings true left-hand and right-hand control to your H&K USP full-size pistol. Whether you're a southpaw shooter, transition between hands during defensive drills, or simply want the flexibility of controls on both sides of the frame, this genuine H&K component delivers the reliability and fit you expect from the manufacturer. The kit includes both lever assemblies and the roll pin needed for installation, making it a straightforward upgrade for USP9, USP40, and USP45 platforms.

H&K engineered the USP line for serious users—competitive shooters, law enforcement, and armed professionals who demand consistency and durability. An ambidextrous safety is a natural fit for that mission. Switching to this lever kit preserves the factory feel and ergonomics of your pistol while removing the guesswork of cross-hand shooting or fumbling for controls positioned only on one side.

This is a genuine H&K part, not a third-party clone, so you get exact tolerances and material quality matched to your USP frame. If you own a full-size USP in any of the common calibers, installing these levers is a smart move for defensive readiness, range versatility, or competition prep.
