thanks bac for the 1911 info. though i'll never be able to afford the high ends, the les baer info is invaluable. for the last 25 yrs., production 45's have been all i've been able to afford. the trs is gonna change that unless my iraqi dinars are revalued 3 to1. i'm not a colt fanboy, i've just been very lucky with them. 6 to date and not a problem. can't say the same for kimber but 1911tuner helped me figure that out and wilson combat is gonna fix it. thanks again for the effort. you've helped more than you realize.
