Looking to get a m45 in the coming months, but I'd like to use it as a suppressor host.

It doesn't appear they are offered with a threaded barrel at all, and I don't want to kitchen table fit a new barrel into a brand new premium 1911...

What's a man to do? Are there any 'smith retailers out there that will do the work before I even take it out of the box?

The gunsmith in my AO is a hackjob embarrassment that would probably fuck up milling a 80% lower, so local is out of the question. I don't think ADCO does pistols? They're a couple hour drive anyway.
