1911 From Scratch?

If your starting with a Wilson frame and slide, I'd use a lot of Wilson parts.
Sounds like they are helping you out and might give you a discount on parts also...and some "advise" if you need it.

If you need to save some money they have a "value line" of parts also...use them and "upgrade" later if you ever need to.

I've always wanted to take Sample's class and build a longslide 10mm, I think it would be fun, greatly enhance my 1911 knowledge, and I would get one hell of an incredibly unique gun out of it! - http://www.1911patriotcop.us/class.html

I built one 3 years ago using an Armscor frame ($95), Kart barrel ($130) and a gunshow special Colt slide ($45) and parts from http://www.cdnninvestments.com/
Some 72 hours of fitting and $425 later, I couldn't be happier.
I built it myself, it works, and I got all the parts that I wanted. I use it mainly for USPSA competitions.
If you are patient and has some good mechanical skills, I say go for it!
