Reliability Preparation
This is stage of reliability preperation should only be undertaken once you have completed the regular reliability preperation. It involves more complex disassembly and there is a greater risk of messing something up if you over do it. You will need the same 400-600 grit sandpaper as before, plus some common disassembly tools and a few drill bits.
Remove the allen screw on the top of your slide that retains your firing pin. Be careful, the pin is spring loaded and will shoot out the rear of the slide with force if you do not contain it.
24. Polish the surface of the firing pin stroking lenghtwise, in the direction of travel. DO NOT sharpen the point of the firing pin. Don't miss the flat spot on the rear of the pin. It does not have to be perfectly smooth, just take off the rough edges.
25.. Polish the outside of the firing pin spring lengthwise.
26. Lightly polish the bottom of the set screw where it would contact the firing pin.
no pic. Using a drill bit the size of the firing pin hole (on the breech face side) work it in and out of the firing pin hole a few times by hand to deburr it.
no pic. Using a drill bit a few sizes larger than the firing pin hole, lightly champher the firing pin hole on the breech face side. This will make it more difficult for debris and grime to build up.
Using the appropriate size punch and a solid surface, drive out the roll pin holding in the extractor. It is under spring pressure, so contain it.
27. Lay a piece of sandpaper on a flat surface. lay the extractor on the sandpaper and polish both sides lightly by sliding it around on the paper. This ensures an even, flat sanding You don't have to polish the entire surface, just take of the rough edges. Do not change the shape of the claw that engages the case rim.
Do not polish the roll pin. You want it to be a tight fit that will not fall out.
Reinstall in the reverse of how you took them apart. The firing pin goes in with the flat part up. tighten the screw down until it just touches the firing pin, then back it out one half turn. Verify that the firing pin moves freely.
The slide stop / ejector and trigger bar are stamped steel. As such they have one side wher the edges are sharp and need special attention
28. Using sandpaper on a flat surface, polish the slide stop / ejector. Just take off any sharp edges.
29. Polish the slide stop / ejector spring, paying special attention to the ends.
30. Polish the trigger bar, using the sandpaper on a flat surface method. Do not change the shape of the tab that engages the hammer.
31. Polish the edges of the hammer using sandpaper on a flat surface. This is a good time to polish the hammer face again.
32. If it needs it, polish the hammer pin.
Do not polish the aluminum frame.
Thoroughly clean all parts. Compressed air is helpful, but not required. It is a good idea to touch up any exposed metal using cold blue. This protects the metal and allows you to monitor wear. Lubricate as normal and reassemble.
If you are working on a Kel-Tec P32, there is a trick to putting the frame back in the grip.
