Loaded chamber indicator

The extractor of the USP Expert pistol doubles as a loaded chamber indicator anytime either a live cartridge or an empty case is present in the chamber. A red painted portion of the extractor, or its protruding tactile feel, indicates the chamber is loaded.

Tools provided with the USP Expert include a 1.5 mm alien wrench for adjusting the trigger stop and a screwdriver for adjusting windage and elevation on the rear sight.

Many HK pistols are equipped with a patented HK Lockoutâ„¢ device.This component replaces the lanyard loop insert in the frame and when engaged locks the handgun's action by blocking any movement of the trigger, the hammer, and the slide. The handgun is locked and can not fire until unlocked. The Lock-Out control plate is accessible through the pistol's magazine well (see figure S6A).

Figure 56A Turn the key clockwise to lock the action

Use the two pronged key supplied with the pistol to lock or unlock the pistol as desired.When the holes on the Lockout Device are horizontally positioned the pistol is locked and can not be fired (see figure S6B).
