Re: Polishing the LCP Barrel Feed Ramp & Throat
P7, different folks have different techniques but what works for me, is to first polish the feedramp and chamber entry (not the end of the chamber where the rifling begins) with 400 or 600 grit wet/dry paper, back and forth several times. To get inside the chamber entry, wrap a piece of the wet/dry paper around a pencil or suitable size dowel. Afterwards, do the same thing with 1000 or 1200 grit wet/dry paper. 'Final step is to polish at medium speed with a Dremmel, FELT bullet tip and Flitz polishing compound - again, the feedramp and chamber entry. The goal is to polish NOT to take off metal or alter the geometry of the feedramp in any way. Polish to a high lustre and clean the barrel of all residue. With larger caliber guns, feedramp and chamber entry polishing comes under the heading of optional assuming the gun feeds, fires and extracts with no problems. In these little guns, where tolerances are tight and there is not a lot inertia to drive things home, polishing IMHO is very important, easy to do, and will not harm your gun in any way.
No fluff and buff required with the LCP.
