Howdy,
So I just finished slicking up a Braztech '92 .45 using the NKJ video and a bunch of prior gunsmithing experience...but with no previous work on the '92...which leads me to this question. Very happy with how it came out...with one exception--if I cycle the gun fast, it runs like a champ...but beats up the cartridge rims a bit. If I cycle it slow, everything works as advertised until the cartridge rim hits the front "ramps" in the cartridge guides. It hangs up there. It seems the ramps are too steep for the bolt to push the rim "up and over" the slots in the guides.
I've heard of shimming the guides, but there doesn't seem to be much room in there as is...it barely clears. Is this where I should start looking, or is there something else this could be? Stoning the top front edge of the cartridge guide slots?
