• Pull out the recoil spring from the central block (Fig. 15). • Holding the slide with the sights turned upward and slightly inclined (front sight higher), remove the barrel by rotating the barrel itself (counter-clockwise looking at it from the rear) (Fig. 16). CAUTION: No further disassembly is recommended unless done by a competent gunsmith. REASSEMBLY NOTICE: The numbers in the figures refer to the photos on pages 2 and 85. Reassemble the pistol following the Field Stripping procedure in reverse order. • Insert the recoil spring - spring guide assembly (pointed end) inside the central block (Fig. 17). • Hold the slide in your hand with the sights turned downward and with the other hand insert the barrel in the slide seat, initially keeping it slightly inclined and with the double cam facing upward (Fig. 18). • Push the barrel against the slide head rotating it axially so that the locking lugs lodge in the recesses of the slide. • The central block/recoil spring and its guide assembly should be mounted with the flat head of the guide inserted in the appropriate hole of the slide below the barrel muzzle (Fig. 14). • Lightly push the central block/recoil spring and the guide assembly forward and press it on the barrel so that the central block tooth engages the barrel double cam (Fig. 19). • Turn the slide upside down and reinsert the guides of the frame in the slide rails (Fig. 20). • Paying attention that the central block correctly centers its frame seat, retract the slide few millimeters beyond the rear end of frame, until it clicks into the locked position. • Retract the slide to check the correct assembly operation. • Decock the hammer. - by operating the manual safety/hammer decocking lever (model F) - by operating the hammer decocking lever (model G) - in model D, the hammer is already decocked. 66
