I have heard some Kimbers suffer from a too tight chamber.

What should a properly polished chamber feel like with a new round in it? A little play or none at all. The reason I ask is I polished my chamber last night with a dremel polish bit (looks like a .50cal flat bullet)and notice a little wiggle room. I did not check this prior to polishing, so I don't know if I changed dimensions. Is a polishing bit even abrasive enough to do harm? It seems to soft to do harm to me. I did not use any polishing compound as the dremel bit is supposed to be impregnated with it. I noticed a lot of the tan polishing material when I was done but no metal dust at all.

The whole pistol is, I'm certain, hopelessly screwed up and should be sent to me immediately


Depending on what the size of the cartridge you are using, a little side to side wiggle is fine. Usually the chamber doesn't need to be poilished, but sometimes the throat can use a little buff, but unless there are problems in feeding, I leave mine alone. If you need the exact chamber specifications they are in Kuhnhausen's books among others.
