Jeep one more thing are USPSA member, well we get a magezine called Front Sight and in there was a article by Brazo who is a big competition pistol smith he makes some fine guns, he talks about a customer who had exstracting issues and he showed a chart od the dimesions of different brass I think this guy was shooting 38 super or super comp and by changing to different brass that solved the problem, I found it hard to believe, I feel like Will Shuemann told me if a gun is built correct in a 1911 it should shoot anything that is setup properly with no problems, in case you are not familiar with Wil he is the GURU of 1911s, (Shuemann barrels)
