8. Use a small tool to depress the head of the firing pin impeller, and turn the safety-lever a little farther upward, then push the safety out toward the left. CAUTION:The small lock pin on the right side will be released as the safety clears it. Restrain the pin and its spring, and remove them upward from their recess in the slide.
9. Remove the safety toward the left side of the slide.
10. With a small screwdriver, pry out the pin at the lower rear of the trigger and remove it toward the left. This will release the magazine safety and its spring to be removed to the rear, into the magazine well.
11. If the hammer pivot has not been removed, pry the slide hold-open spring out and down, and detach it from the hold-open block toward the rear. The spring retains the block, and the block can now be slid straight up and out of the frame.
12. Lift the slide latch to clear the frame at the rear, and move it toward the left.
13. After the slide latch is moved slightly outward, use a small tool to lift the rear arm of the latch spring from its recess in the latch and remove the latch toward the left side.
14. The trigger bar and its spring are shown in assembled position on the right side of the frame.
15. Depress the upper arm of the spring from its groove in the underside of the bar, and move it out toward the right. Remove the spring from its recess upward.
16. Remove the trigger bar toward the right side.
17. Removal of the slide latch and its spring will free the trigger pin to be taken out toward the left. The trigger and trigger spring are then removed up out of the frame.
18. The magazine catch button is retained on the cross-shaft of the catch piece by a vertical pin. When the pin is drifted out, the button and spring are removed toward the left, and the catch piece toward the right.
19. Drifting out the roll pin at the lower rear of the grip frame will free the plug which forms the housing and base for the mainspring. Removing the housing downward will relieve the tension of the mainspring and allow its removal. Drifting out the large pin at the upper rear of the frame will free the hammer and hammer strut for removal from the top. Drifting out the smaller pin at the rear, just below the upper frame opening, will release the sear and sear spring for removal forward, into the magazine well. The two small pins at the top of the frame retain the hammer-drop lever and the ejector, and these parts are removed upward.
Detail Strip–Variations
Beretta Model 92F
Original Beretta Model 92
1.In the safety system of the original Model 92 (and the Taurus pistols), use a roll pin punch to drift out the small roll pin in the base of the safety-lever, downward.
2. Push out the safety pivot shaft toward the right. (Note: It is assumed that at this point the trigger bar and its spring have been removed.)
3. Turn the safety-lever up to the on-safe position, and remove the lever toward the left. CAUTION:The safety positioning plunger and spring will be released upward as the lever is taken out, so control them.
4. Remove the positioning plunger and spring upward. In reassembly, a tool must be inserted to depress the plunger as the safety-lever is put back into place.
Reassembly Tips:
When replacing the trigger bar, insert a tool from the top of the frame to lift the rear arm of the trigger spring, hooking it over the inward projection of the bar.
When replacing the slide latch, remember that the rear arm of its spring must be lifted into its recess on the inner projection of the latch.
When replacing the firing pin and extractor, use a slave pin to hold these parts in place while driving in the retaining pin.
When replacing the safety in the slide, be sure that the flat of its back edge is aligned with the slant of the safety recess in the slide, and that the firing pin impeller is centered in the cross-piece of the safety. When everything is aligned, it can be pushed straight into the slide. When the right end of the safety reaches the lock plunger on the right side, the plunger must be depressed to pass under the end of the safety. When the safety is all the way in, it can be turned back down to normal position.
