I will agree with Deacon on mostly things, the only one I will comment on is magazines. They have changed a lot in recent years. McCormick was bought by Wilson and by far the most widely used by pro shooters and best magazines currently available for 1911s are the cobra mags from Tripp Research. Don't get me wrong I have had good results from Wilson, McCormick, real Colt, and Actmag, but I only shoot cobra mags anymore.
