I posted last, sometime in April, I think. Couldn't find my thread. Anyhow - I am on my first 80% build and it's a Stealth Arms .45 aluminum alloy frame. I got a stainless slide (Remington) and a Briley barrel. The pieces are new and the barrel is one that requires fitting. I'm just getting parts at prices that seem to be reasonable. One of the things is that I want the corrosion resistance of stainless, being that I live on the coast. I also have the Jerry Kuhnhausen manual - Vol 1 And I've been watching videos, mainly by Mosin Virus, since he seems to be focusing on alloy frame 80% builds. So - It's easier to ask here, than it is to try to find info from other sources sometimes. I would have made things easier on myself, if I'd bought a drop in barrel. At this point I need to ream the chamber to fit properly. I have noticed that there's a tool loan/rental thread and I'm undecided whether to try to do it myself or send it to someone. I'd prefer not to invest in a new tool, because I really don't believe that I'll get so hooked on 1911 building as a hobby, that I'll use the tool a lot. If someone could direct me to a gunsmith who'd give me a quote or a source for a decent rental reamer, that would be appreciated, tremendously! Thanks for following along and providing advice I'll be posting in the future, I'm sure, as I am just starting on this And it's more complicated than I expected.
