not if you have been droping the slide on an empty chamber (a major nono with the 1911). It has a floating sear, and the jaring from dropping the slide on an empty chamber can make the sear/hammer connection jump, causing the sear to become damaged, and eventually leading to a fractured edge. I had a Para P12 that the previous owner had done just that, and one day it stopped shooting on follow up shots. It would hang at half cock because the edge of the sear which was all galled up and chipped had caused chipping on the hammer. had to replace both pieces and it ran like a top after that. by the way, turning that pistol into a series 70 didn't fix a darn thing, and to do that with a kimber takes a whole lot of work.
