Field Stripping

Make sure the pistol is unloaded. Remove magazine by depressing magazine release button.

Holding pistol with the left hand, press disassembling latch release button with forefinger.

With right thumb rotate disassembling latch counterclockwise until it stops.

Pull forward slide-barrel assembly, recoil spring and spring guide.

Pressing recoil spring guide head (caution: the recoil spring is under tension), lift the recoil spring guide and let the spring stretch slowly. Separate barrel-monoblock from slide.

The counterweight slide can be removed by unscrewing the locking and adjusting screws using a 4 mm Allen key.

NO FURTHER DISASSEMBLY IS RECOMMENDED UNLESS DONE BY A COMPETENT GUNSMITH.

Assembly

Assemble following the Field Stripping procedure in reverse order. Pay attention to the following points:

The barrel should rest perfectly against the slide (the extractor must lodge in its groove in the barrel).
The recoil spring guide head should lodge in the center of its seating in the barrel base.
When rotating the disassembling latch, the slide should be in the closed position (aligned with or just beyond the rear side of frame).
