• rear sight with micro-meter adjustment for windage and elevation (USP Tactical, USP
Expert, USP Elite, USP Match)
• high profile front sight ((USP Tactical, USP Expert, USP Elite, USP Match)
• extended threaded barrel (USP Tactical, USP Compact Tactical)
• barrel with O-ring (USP Tactical, USP Expert, USP Elite, USP Match
• extended foorplate on mag a zine
• loaded chamber indicator (USP Tactical, USP Expert, USP Elite, USP Match)
• Match trigger parts (USP Expert, USP Elite, USP Match)
• Barrel weight (USP Match)
NOTE: Not all USP Specialized Models are available in all regions.
Adjustable trig ger stop
The trigger stop for the USP Specialized Models is lo cat ed on the trigger and limits the
trigger travel im me di ate ly after the ham mer 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 over-travel 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 (see Fig. 28).

rear sight
USP Specialized Models use micrometer rear target sights which are adjustable for
windage and el e va tion. Using an appropriate screw driver, the rear sight can be precisely
adjusted to align with the point of impact (Fig 29 & 30).
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;
Depending on the model, 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.
Depending on the model, 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 (target) sight
The high profile front sight is mounted on the slide in a dovetail and does not require
adjustment. On USP models with threaded barrels, it also allows the operator to obtain a
normal sight picture when an optional sound suppressor is mounted (see Fig 31).

The 128.5 mm (5.06 inches) hammer forged po lyg o nal 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
