Welcome to TFF. As you know. The Norinco is an excellent platform for a build and is one of the few 1911's that Wilson Combat will perform custom work on. I remember the 1st one I ever bought. Paid $260 out the door. I have owned several over the years.
These pistols are an exact Colt clone so all parts will fit. Everything you need is available from www.brownells.com
Keep us posted on your progress.
