Heavy Lube
Lubrication runs down the surface when it is held in a verti-
cal position
No heavy lube is required on the HK USP.
Reapply lubricant periodically during firing as it burns off
from the heat. Apply lubricant using a clean shaving brush,
cotton swabs, patches, or rag. A spray bottle of lubricant
also works well when using compressed air to circulate the
lubricant into all parts and to remove the excess from the
pistol.
Troubleshooting Problems and Repair 
The ten inspection areas listed above should be checked
prior to contacting HK if your pistol fails to function 
properly. Other common causes of problems that are oftenoverlooked include:
•  Fouled or improperly lubricated pistol 
•  Bad ammunition 
•  Damaged magazines
•  Operator error
If your HK USP still fails to function, please contact Heckler
& Koch Customer Service at (703) 450-1900 for the name
and address of your nearest HK Authorized Repair Facility.
Military and law enforcement users, contact your unit
armorer or HK Customer Service.
NOTE: If after reviewing this manual you still have
questions, please contact your HK dealer or
telephone the Heckler & Koch Customer Service
Department. Please address any suggested changes
or improvements to this manual to the HK Creative
Services Department.

The Mark II HK UTL can be quickly attached or removed
from the pistol and provides an immediate source of
illumination. With easy to use controls, the UTL ensures law
enforcement professionals or home owners can identify po-
tential threats in critical low light situations.
Using a USP fitted with a UTL makes alignment of the light
and pistol easier than using a separate flashlight. A separate
light can be difficult to use and hold while manipulating a
pistol in a life threatening situation. The UTL can also be
detached from the pistol and used in place of a conventional
flashlight.
The Mark II UTL is designed and manufactured by Insight
Technology Inc. (ITI), the same firm that created the special
flashlight and laser aiming module used on the .45 caliber HK
Mark 23 pistol developed for the US Special Operations
Command.
Available exclusively from Heckler & Koch, Inc., the Mark II
UTL fits all variants of the USP pistol, including the USP
Compact, and can be purchased with an optional remote
cable switch, and tactical nylon carrying pouch.
USP ACCESSORIES
Heckler & Koch and Insight Technology Inc. have developed a
powerful accessory light that attaches to the HK USP pistol.
Smaller and more powerful than a conventional flash-light,
the Mark II HK Universal Tactical Light (UTL) adds a dimen-
sion of tactical flexibility to the USP absent in other modern
semiautomatic pistols.
Figure 42
The Mark II UTL is a compact and powerful 
accessory light for the USP.  
						

							43
Key features of the HK UTL
• compact and rugged design fits all models of the USP
and USP Compact pistol
• lamp brightness superior to most flashlights  
• focusable beam, spot to flood
• clip-on/clip-off design, can be installed or removed in
seconds
• integral on-off switch prevents inadvertent operation
Figure 43
The HK Mark II UTL can be installed and removed
from any USP in seconds with one hand.• uses easily replaceable standard lithium batteries
• fingertip on-off operation (toggle switch pushed to
right, intermittent on only, toggle switch pushed to
left, intermittent and constant on)
• optional remote switch and accessory pouch available
Other USP Accessories
A variety of USP accessories and enhancements are available
and include tritium sights, click adjustable sights, a sight
installation tool, and ambidextrous control levers. Contact

USP .45 Parts List (Parts exclusive to the USP45 shown in italics)  
						

							48
SECTION 9   USP TACTICAL
The HK USP Tactical pistol has all of the features found on
the standard USP45 with the addition of the following:
• adjustable trigger stop
• rear sight with micro-meter adjustment for windage
and elevation
• high profile front sight
• extended threaded barrel with O-ring
• extended foorplate on magazine 
• loaded chamber indicator
Adjustable trigger stop
The trigger stop for the USP Tactical 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 equipped 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 Tactical 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). 
						

							High profile front sight
The high profile front sight is mounted on the slide in a
dovetail and does not require adjustment. It allows the
operator to obtain a normal sight  picture when an optional
sound suppressor is mounted.
Extended barrel with O-ring and muzzle threads
The 128.5 mm (5.06 inches) hammer forged polygonal
barrel is engineered for a high level of accuracy. The high
temperature rubber O-ring located towards the muzzle
holds the barrel tightly in the slide during firing and
enhances accuracy. The left hand threads used on the barrel
of the USP Tactical pistol will accept only those accessories
designed for the pistol. The MK23 sound suppressor cannot
be attached to the USP45 Tactical pistol!  A specially
designed sound suppressor is available for the USP45
Tactical pistol.
CAUTION: When used with a suppressor, use only
HK approved suppressors as currently made by
Knight’s Armament Company or Brügger & Thomet
of Switzerland. Even though all types of high velocity
supersonic (+P) ammunition  can be fired, for
maximum effectiveness (suppression) only subsonic
ball ammunition should be used when a sound
suppressor is attached.
49
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 Tactical pistol. Prolonged use of
+P ammunition through the pistol with the sound suppressor
attached is not recommended. Assembly and disassembly of
the slide, barrel, and frame on the USP Tactical is the same as
other full-frame USP pistols (see pages 28-33 in this manual).
Extended foorplate magazine
The USP Tactical 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.
Loaded chamber indicator
The extractor of the USP Tactical pistol doubles as a loaded
chamber indicator anytime a live cartridge or 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 Tactical include a 1.5 mm allen
wrench for adjusting the trigger stop and a screwdriver for
adjusting windage and elevation on the rear sight.
