I just bought a Kimber Custom Crimson Carry II, and have begun the slow process of breaking it in. When I took it home I immediately field striped it and gave it a thorough cleaning as well as properly lubricated it before I took it to the range. Anyway after I shot it I took it home and cleaned it out again because I was just always taught that you should always do that, but a buddy of mine who is pretty knowledgeable about these things said it would have been good to let it stay dirty for the first 500 rounds or so to really break it in. Is that true? What do you think, keep cleaning it every time, or let it stay dirty for the next 400 rounds or so?
