In this thread, http://www.firearmstalk.com/forums/f57/ftf-problems-12697/, Canebrake suggested one solution would be a new spring, probably 16#, from ISMI. As everyone is no doubt entirely tired of hearing, I was suffering the same problems as the thread originator. One new 16# spring from ISMI and 400 rounds later, NO PROBLEMS!!! We may disagree politically, but Canebrake knows his stuff regarding the 1911. Many thanks. (If anyone else suggested the same and I didn't notice, kudos to you as well).
