How to polish internals on a Glock

Disclaimer: I will not be held responsible for damages caused to your gun by you; proceed at your own risk.
Supplies needed:
Black permanent marker
50 rounds of ammunition or more
Gun oil( wet sand agent)
120 grit Wet/dry sand paper
1000 grit wet/dry Walmart auto detailing area
3000 grit wet/dry Walmart auto detailing area
Metal paste polish . I used metal-glo works great.

1.Take your trigger internals out. Black all the metal parts with the marker and let dry.
 2. Reassemble dry fire about 10 times.
3. Take apart and look for marker worn off areas. Remember these areas, pictures write down.
4. Reassemble and shoot 50 rounds.
5. Disassemble and look for new worn areas
6. Worn areas from step 2 get dry 120 until metal is bare.
7. Wet sand 120 worn parts from step 2 & 4
8. Dry 1000 grit step 7 parts
9. Wet 1000 grit whole assembly til bare and smooth
10. Wet 3000 grit whole assembly til silky smooth
11. Apply paste let sit a minute
12. Rub paste off with soft cotton cloth
13. Continue step 12 until you are getting clean cotton( no grey/oxidation etc)
14. Clean the rest of your gun
15. Make sure to reapply oil to trigger oil area
16. Enjoy your smooth trigger

This will make the biggest difference on new/newer guns. If your gun has seen 1000s of rounds don't expect a lot of improvement.

****BE CAREFUL **** with steps 6-8 if you remove to much metal the weapon may function differently.  I also polished my rails, safety plunger,etc. If you polish the extra parts especially the rails be very careful take to much off and you will need a new frame.
