USP EXPERT
The HK USP Expert pistol has all of the features found on
the standard USP45 and USP40 with the addition of the
following:
• match trigger parts
• adjustable trigger stop
• rear sight with micro-meter adjustment for windage &
elevation
• front target sight
• extended slide & barrel with O-ring
• extended foorplate on magazine 
• loaded chamber indicator
Adjustable trigger stop
The trigger stop for the USP Expert pistol is located on the
trigger and limits the trigger travel immediately after the
hammer has been released. It is adjusted by use of the 1.5
mm allen wrench that comes with the pistol. By turning the
1.5 mm set screw clockwise, the overtravel of the trigger
can be reduced. Care must be exercised in making this
adjustment as the screw can be adjusted far enough to
prevent the proper operation of the double action and
single action trigger.
Rear sight
The USP Expert uses a micrometer rear target sight which
is adjustable for windage and elevation. Using an appropriate
screw driver, the rear sight can be precisely adjusted to align
with the point of impact.
Adjusting the elevation
Rotate the elevation adjusting screw on the top of the rear
sight in the desired direction with the screwdriver supplied
with the pistol; rotating it clockwise lowers the point of
impact approximately 1 cm (0.39 inch) per click at a range
of 25 meters (27.3 yards), rotating counterclockwise raises
it the same amount per click.
Adjusting the windage
Rotate the windage adjusting screw located on the right
side of the rear sight in the desired direction with the
screwdriver supplied with the pistol. Rotating clockwise
moves the shot to the right. Rotating counterclockwise
moves the shot to the left. Each click shifts the point of
impact approximately .5 cm (0.2 inch) to the left or the
right at a range of 25 meters (27.3 yards).

Front  target sight
The front target sight is mounted on the slide in a dovetail
and does not require adjustment.
Elongated target slide & extended barrel 
The additional length of the elongated target slide aids the
balance of the USP Expert during target shooting. Together
with the USP Expert’s 5.20 inch hammer forged polygonal
barrel, these components contribute to the high level of
accuracy the pistol achieves. The high temperature rubber
O-ring located towards the muzzle holds the barrel tightly
in the slide during firing and enhances accuracy. Place a drop
of lubricant on the barrel O-ring during cleaning and replace
it by hand if/when necessary. Spare O-rings are provided
with each new USP Expert pistol. Assembly and disassembly
of the slide, barrel, and frame on the USP Expert is the same
as other full-frame USP pistols (see pages 28-33 in this
manual.)
Figure 53
O-ring on barrelExtended foorplate magazine
The USP Expert pistol uses magazines with extended
floorplates; providing a larger, and for many shooters, a
more comfortable gripping area. It also protects the
magazine if dropped and assists in the manual removal of
the magazine in the event a stoppage occurs. This floorplate
is removed and installed like the standard floorplate (see
pages 34-37 in this manual. The use of an extended
floorplate does not affect the magazine capacity. Law
Enforcement/Military models of the USP40 Expert have a
special jet funnel feature on the grip.
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 allen
wrench for adjusting the trigger stop and a screwdriver for
adjusting windage and elevation on the rear sight.

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).
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 Lock-
Out Device are horizontally positioned the pistol is locked
and can not be fired (see figure 56B).Figure 56B
Locked position
When the holes on the Lock-Out Device are vertically
positioned the pistol is unlocked and can be fired (see
figure 56C).

Unlocked/fire position    
						

							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.
