How many of you polish the feed ramp of your autoloader regardless of whether or not you're having feeding problems? I have a Glock 19 (gen3) that I bought used and has been flawless through about a thousand rounds. The feed ramp just looks a little rough though. Not bad but could definitely be better with some q tips and polishing compound. I know, "if it ain't broke don't fix it". I'm just curious about how many make a feed ramp polish a routine "mod" to their pistols (or rifles for that matter).
