I would talk to the local gunsmith. Anybody who works with 1911's should be up to speed on fitting a barrel.
Always try the nearest gunsmith first, somebody that you can visit personally. - Just ask if they work on 45 autos when you call. Explain that you have a new barrel that needs to be properly fitted.
