HK 50248613 USPBlack Detachable with Extended Floor Plate 18rd 9mm Luger for H&K USP Expert

The HK USP Expert 9mm 18-round magazine with extended floor plate is a genuine H&K spare mag built to the same reliability standards as your USP platform pistol. Whether you're stocking up for the range, building a defensive loadout, or simply want reliable backup mags on hand, this 18-round capacity keeps you fed through extended shooting sessions. The extended floor plate provides a more ergonomic grip for faster, smoother reloads—a practical upgrade over the standard floorplate.

H&K engineered these mags to work across the full USP 9mm lineup, making them a versatile choice if you own multiple variants of the platform. The extended floor plate design does mean the magazine will protrude below the magazine well on a standard USP unless you have a Jet Funnel mag well installed, so plan your setup accordingly. With or without the funnel in place, you get the same reliable feed and retention you'd expect from factory H&K components.

This is OEM ammunition storage—no aftermarket compromise. Built to strict H&K tolerances, these mags are designed to cycle reliably for thousands of rounds. If you're serious about your USP, genuine factory mags are always the smart choice over mixed-brand alternatives that can introduce feeding inconsistencies.
