Automatic Pistols Assembly/Disassembly. J B Wood

      The “Back-Up” is made entirely of stainless steel, and, as its name implies, it is intended as a “backup” gun for the law officer, for use if his regular sidearm is disabled, empty or lost during a serious social encounter. The little Back-Up is also popular as a self-defense pistol for the private citizen. The excellent and mechanically simple design is the work of John Raymond Wilkinson.

       Detail Strip:

      1. With the magazine removed and the hammer in the fired position, use a non-marring drift to drive out the breechblock cross-pin toward either side.

      2. With a non-marring tool such as a nylon-tipped punch or a wooden dowel, nudge the breechblock upward, working through the magazine well.

      3. Remove the breechblock from the top of the slide.

      4. Allow the slide to move forward until it clears the, short slide rails at the rear of the frame, and lift the slide upward at the rear to clear the barrel. Move the slide assembly forward off the barrel and frame. Remove the recoil spring and its guide from the frame.

      5. Drifting out the small cross-pin in the breechblock will free the extractor and its coil spring for removal upward. CAUTION:Removal of the extractor will also release the firing pin and its spring, so control the firing pin as the extractor is removed. The circular spring, which retains the breechblock cross-pin, is staked in place on the left side, and no attempt should be made to remove it.

      6. Use an Allen wrench of the proper size to back out the grip screws. Lift the grip panels at the rear for removal.

      7. With a small tool, detach the trigger bar spring from its groove in the rear lower edge of the trigger bar, and move it inward, behind the bar. Restrain the trigger, and remove the trigger bar toward the left.

      8. Removal of the trigger bar will release the trigger and its spring to move forward, and it can then be removed toward either side. Take care that the small trigger spring is not lost.

      9. Remove the safety lever toward the left. Take care not to exert outward pressure on the front of the lever.

      10. Drift out the small pin at the top of the frame enough to partially release the ejector. It is not removed at this time.

      11. With the hammer in the fired position, restrain it, and push out the hammer pivot toward the right.

      12. Ease the hammer out upward, along with its strut and spring, and remove the ejector, which will also be released. CAUTION:The hammer spring is under tension.

      13. The hammer strut is easily removable from the hammer by turning it straight out to the rear and sliding it out of its seat in the hammer toward either side.

      14. Drift out the sear cross-pin, and remove the sear forward, into the magazine well.

      15. Push out the pin, which retains the sear spring and the trigger bar spring. Before removal, note the position of the two springs to aid in reassembly.

      16. Drift out the cross-pin at the lower rear of the grip frame, and remove the magazine catch downward.

      17. Move the grip safety upward to clear its lower lugs from the frame, then remove it downward and toward the rear.

      18. The inner tips of the grip safety spring are locked into holes on each side within the backstrap. Squeeze the inner arms of the spring together to clear the tips from the holes, and remove the spring toward the rear.

       Reassembly Tips:

      1. When replacing the hammer and hammer spring assembly, be sure the spring and strut are attached to the hammer with the double curve of the strut in the orientation shown. When the hammer is in position, start the hammer pin through, then insert the ejector before pushing the hammer pin into place. As the hammer is inserted, be sure the lower tip of the spring strut enters the hole in the top of the magazine catch.

      2. After the trigger bar/disconnector is back in place, insert a small tool to re-engage the trigger bar spring with its groove in the rear lower edge of the bar.

      3. Note that the breechblock pin has a groove near one end. This groove must go on the left side of the gun, to engage the spring clip in the breechblock.
