LOCK-OUT DEVICE
Many HK pistols are equipped with a patented HK Lock-
Out™ 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 56A).

WARNING: The HK Lock-Out Device is not a
substitute for safe gun handling practices. Never point
the muzzle of the pistol in an unsafe direction (at
yourself or others). When the Lock-Out Device is
placed in the locked position the slide is locked in the
closed position and can not be moved! Forcing the
slide rearward while the gun is in this  locked position
will damage the USP.
