Buy some books and read up. Talk to others who shoot and build competition guns. Asking these questions on an internet forum is going to get you lots of really dumb uninformed opinions mixed in with the intelligent answers. The standard reference book is Jerry Kuhnhausen's 1911 A Shop Manual Vol. 1. Wilson Combat and Ed Brown both make very high quality parts and guns. But all of those parts will need to be precisely fitted together correctly. A 1911 is a system. Change one part and it affects the whole system. Anyone who tells you that their part will "drop in" is trying to get your money. It is very possible to build an excellent gun from a Springfield Mil Spec with the factory original parts and the first order of business would be a match grade bbl and bushing. (again, fitted to your gun). But I have worked on quite a few Mil Specs that shot very tight groups from the factory bbl. with only a new bushing fitted. Make the gun reliable first and then tweak its accuracy.
