Be sure you pistol is clear by following the instructions on the inside cover or page 9.
NOTe: Photographs in this section show USP Compact models, disassembly and
assembly of full-size and specialized USP models is the same.
Pistol Disassembly (Field stripping)
1. Depress the slide release and allow the slide to move forward.
2. Using the firing hand, re tract and hold the slide to the rear so that the axle of the
slide release is visible through the recess in the left side of the slide (See Fig. 10).
3. With the non-firing hand, completely remove the slide release from the left side
of the frame by pressing on the axle of the slide release from the right side of the
frame.
Fig. 10
CAUTiON: Hold the recoil assembly in place while re mov ing the slide from the frame.
if not, this assembly could be released under spring ten sion and could possibly cause
injury to per son nel, or become dam aged or lost.
4. Remove the slide with bar rel and recoil spring assembly by slid ing it forward off of
the frame. (See Figure 11)
Fig. 11
5. Carefully remove the recoil spring assembly from the barrel and slide by lifting up
on the rear of the recoil spring guide rod. The entire assembly can now be lifted
out of the slide (see Figure 12)
6. Remove the recoil spring assembly. The USP series pistols use a “captive” recoil
spring assembly, dis as sem bly is not recommended.
7. Lift the rear of the barrel by the locking block and with draw it from the slide.

NOTe: Disassembly of the pistol is now com plete. Only an HK certified armorer
should disassemble the pistol further.
Pistol Assembly
1. Position the barrel in the slide so that:
• The muz zle of the bar rel fits in the hole in the front of the slide.
• The lock ing block por tion of the bar rel fits with in the ejec tion port and the an gled
lock ing sur fac es of the lock ing block are vis i ble along the bot tom of the slide.
2. Install the recoil spring assembly into the slide so the front of the recoil spring guide
rod engages in the small hole provided in the front of the slide.
3. Align the op pos ing an gled lock ing sur fac es on the rear end of the re coil spring guide
rod with those lo cat ed on the bot tom of the bar rel lock ing block. (See Figures 13 &
14)
4. Push the rear of the recoil spring as sem bly for ward enough so that the re coil spring
re tain er can be en gaged on the shelf pro vid ed on the front of the bar rel lock ing
block. (See Figure 13, 14, & 15)
