							32NOTE
Disassembly of the pistol is now complete. Only
an HK certified armorer should disassemble the
pistol further.
Pistol Assembly-
1. Position the barrel in the slide so that:
• The muzzle of the barrel fits in the hole in the
front of the slide.
• The locking block portion of the barrel fits within
the ejection port and the angled locking surfaces
of the locking block are visible along the bottom
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 opposing angled locking surfaces on the
rear end of the recoil spring guide rod with those
located on the bottom of the barrel locking block.
(See Figures 34A & 34B) 5. Carefullyremove 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 32)
6. Remove the recoil spring assembly. The USP
Compact uses a “captive” recoil spring assembly,
disassembly is not recommended.
7. Lift the rear of the barrel by the locking block and
withdraw it from the slide.
