system, ambidextrous safety, and a reversible magazine catch for left-handed shooters, along with a capacious 13-round magazine. A companion gun, the Model 81, is identical mechanically, but is chambered for the 32 ACP cartridge. Although it has many features, the pistol is not unnecessarily complicated. While there are some small differences, the instructions can also be generally applied to the 380-caliber Model 85 and the 22 Long Rifle Model 87.
Field Strip:
1. The takedown-latch release button is located on the left side of the frame, just forward of the trigger. Remove the magazine, and leave the hammer at rest.
2. The takedown-latch is located on the right side. Push the latch release button and turn the latch down to the position shown.
3. The slide assembly can now be run forward off the frame.
4. Push the recoil spring guide forward, lift it at the rear, and remove the guide and spring from the slide.
5. Move the barrel slightly forward, and remove it from the bottom of the slide. Gun is now field-stripped.

Detail Strip:
6. A vertical pin in the slide retains the extractor and its spring, and the extractor pivot lug retains the firing pin and its spring. The pin should be drifted out toward the top.
7. The magazine safety is a round-wire torsion spring located on the right side of the frame, hooked into an opening in the trigger bar.
8. To remove the magazine safety spring, flex its lower arm out of its recess in the frame and move the lower loop of the spring outward.
9. Turn the spring to free its upper hook from the opening in the trigger bar, and remove the spring to the right.
10. The right safety-lever is retained on the cross-shaft of the safety by a vertical roll pin. Use a roll pin punch to remove it.
11. When the pin is driven out, the right safety-lever can be removed toward the right.
12. With the hammer cocked, remove the left safety-lever and its cross-shaft toward the left. CAUTION: As soon as the safety clears its spring-post, the internal spring and plunger will be released. Keep a fingertip in front of the safety, as shown, to prevent their escape.
13. The positioning spring and plunger are mounted inside the left safety-lever. Take care that these small parts are not lost.
14. Removal of the trigger bar will also release the trigger, allowing it to move forward for easy removal. Take care not to lose the small trigger spring.
15. Before removing the safety-lever, take note of the position of the combination sear and trigger bar spring inside the frame, as it will be released when the safety is removed. Turn the safety-lever into near vertical position, and pull it out toward the left side of the frame.
16. Move the slide latch slightly to the left, and use a small screwdriver to disengage its spring from the recess on the frame. When the spring is free, remove the slide latch toward the left side.
17. The cross-shaft of the slide latch is also the trigger pivot, and the trigger spring can now be removed from the top of the frame. The forward tip of the trigger spring also powers the takedown-latch release button, and the release will not probably fall out of its recess in the gun or can now be removed toward the right.
18. The trigger can now be removed downward, into the interior of the guard.
19. A roll pin at the lower rear of the grip frame retains the frame plug, which is also the hammer spring base. After the pin is removed, the base can be pushed down and out by cocking the hammer.
20. Removal of the spring base plug will make hammer removal easier, but is not absolutely necessary. If the plug is still in place, restrain the hammer while removing the hammer pivot, as the spring is under some tension even when the hammer is at rest.
21. Remove the hammer from the top of the frame.
22. Remove the hammer strut and spring from the top of the frame.
23. The small roll pin at the rear of the magazine well is the compressor for the sear spring and driving it out will release sear spring tension. The larger solid pin above it retains the sear and its spring, and these parts are removed forward, into the magazine well.
24. The two small roll pins at the top of
