I don't know your skill set with fitting parts by hand, but the 1911 is a great platform to build your own on.
You can build a custom for the price of a nice production gun.
I bought my current 1911, S&W E , without much knowledge on the platform. Well, it was JUNK . Barrel was fitted by crutching off the barrel link and it shot patterns at 30ft !
I decided it was so bad I couldn't sell it in good faith, so I set about to make it better myself. I tightened the frame , fitted a Ed Brown barrel to a beveled bushing, polished the trigger, installed ambi tactical safeties, cut the frame up into the area below and behind the trigger guard to cut muzzle flip, installed a high grip safety, and cut a set of G10 grips to fit my paws. Never touched the internals of a 1911 before this build and did all of it with hand tools. The gun will shoot circles around about any 1911 I see tested in the mags. Consitently shoots 5 shot groups right at an inch at 25yds with everything I've tried in it , from basic ball to cavernous HPs. It is a 45acp, but I see no reason why a fella couldn't get a quality frame and build a 10mm hammer while sitting on the couch watching meat eater marathons , lol.
