I have heard a lot about polishing the feedramp. i am a little skeptical about taking a dremmel to it. So with a polishing bit and the cleaner am i able to cause any damage? I am sending my wife's keltec pf9 and plr 16 to keltec, they do it for free.
I've polished a number of feed ramps on my guns and I usually start with 600g wet/dry sand paper, followed up with 1200g wet/dry and then finish with Flitz polish creme- working in the same direction as the cartridge feed. Works great!
