One of the gentlemen on the car forum that I frequent has some of the most awesome 1911's. He had his custom built by Evolution Gun Works. While I haven't any personal experience in dealing with them, he is extremely happy with his which he uses in IPSC/USPSA action shooting (Open division).
If you're interested in seeing a pic, I can ask his permission to post it.
Well it sounds like you dont wanna just buy a high-end pistol from one of the "big names". Heres an idea. Find a frame/slide you like from a well respected maker. Have them fit a barell/bushing/ and maybe the beaver tail. Then find someone you trust locally to fit the small parts. That way your smith will be closer to you in the event you have bugs to work out. And, that would let you pick your favorite grips, safety, trigger, hammer, ect.
Another option is to find a lightly used, quality base model and sent it off to have it built with your choice of parts.
Chances are, though, One of the high end names already makes something to suit your tastes.
Lee, Im curious, what do you have in mind? Purpose built for what?
Im looking around for options for rebarreling/rebuilding my shot-out Kimber, options are endless. I have found different safety, hammers that I like. I think Im going through something similar right now.
I found those at another forum. I think the meat tenderizer is to your enemy doesnt knock your slide out of battery. And the spike on the mainspring housing....well I guess its for when you run out of ammo and want to pummel your enemy. Not real practicle, but wwaaaayyy over the top. :---
