I have done the .25 cent polishing job on all of my Glocks using Flitz and a Dremel tool at low speed probably no more than 5 seconds in any one spot. Have not missed up any parts so far.I have not done so but polishing the hole firing pin might help with it being something for the spring to slip by on. How much more difference it would make?????
