I did a search and couldn't find anything.
I have been building AR's for about a year now. I'm not sure how many ar15's I actually need.
I want to build a 1911. I was wondering where I might find good material about building them, and
some good sources for parts.

There should be a lot of guys here at AR15.com that could help you with your 1911 questions.

M1911.org and pistolsmith.com would be other info sources.

For parts take a look at our own Equipment Exchange, just click on the tab on top of the page.

Here are also good sources for parts:

Caspian Arms
Dan Wesson
Kimber
Para-Ordnance
Springfield Armory
STI International
Chip McCormick
Les Baer
Ed Brown
Kings Gun Works
Wilson Combat
Novak
Wolf Springs
Bo-Mar
Brownells
CDNN Investments
