I was looking at this link, hxxp://www.goldenloki.com/guns/keltec/prep.htm, I removed the (tt, in Http), so the link isn't live, as per forum regs. It shows and explains how to do a 'fluff and buff', on a new pistol, prior to using it, or it can be done at any time if needed. I haven't done it on my keltec, PF-9 as it still is virgin in the box. Is this something that is more common than I assumed, having polished a few feed ramps and done some minor repairs, installing sights, and the like, in my day, should the average guy attempt to use 400-600 grain sandpaper on a pistol. I understand that this may be the equivelant of shooting a couple hundred rounds to "break in" a new weapon, Is it easy to feel how much is enough, my concern is overdoing it. And what pitfalls can those who have done this routine on their pistols suggest ahead of time. Thanks, the term made me laugh, I must admit.
