Scotty45,
I recently built my first 1911. There are lots of pistolsmiths on the 'net that will help you, i.e. Richard Heinie, Les Bengston (retired), et al. There are others that won't help due to liability, etc. If you want to get dealer pricing from Brownells, as well as dealer pricing from such places as W.E. Birdsong (Black-T fame), you can get a C&R (Curio & Relic) FFL (type 03) for $30 and good for 3 years. You WILL recover the $30 and more in savings from Brownells. Example: CMC Frame, Slide, & prefit Kart NM barrel retails for $666, dealer price $500. Granted, you still have to go thru FFL (type 01) for the frame. That cost me $20 (plus no tax).
You will also invest lots of money in tools, but they can be reused (for more pistols). I have $1400 invested, including tools. My CUSTOM CMC,Ed Brown,Cyl&Slide,Richard Heinie, Les Bengston and last Elbert Mays 1911A1 shoots 1" groups at 25 yards from sand bags.
You can do it, but you have to start!
Good luck
