Ok, so I have a few questions about polishing Glock and M&P internals. I get bored at work (I sit behind a desk for 8 hours, on the overnight), so generally surf the web. Usually end up watching stupid people doing stupid stuff on youtube. I came across a few vids on polishing the internals, using Flitz and either a dremmel or q-tip. Now, my questions... 1, does polishing the internals actually make that much of a difference? 2, should this be done only to a "range" weapon, or can it be done to a carry weapon? 3, does it have to be Flitz? or can you use any non-corrosive polish, like never dull?? Also, any reasons why this shouldn't be done, that isn't just a personal opinion, would be welcomed.
