I know that Joe Chambers has fixed some less than optimal work done by other smiths - he's worth giving a call. He's very detail oriented and stubborn (in a good way) about getting things right. You may have a long wait ahead, though. I'm not sure what his backlog is like these days.I need to find one on the list that will take on two 1911 projects that another gunsmith on the list started but appears to have no desire to finish. I know that is going to be a challenge because a lot of smiths don't want to work on something that someone else has messed with. I don't blame them since it's no different turning wrenches and getting someone elses half finished bullshit.
Chen has the coolest idea about 1911 mag wells: shorten the grip and add a magwell that does not make the grip longer than standard. A couple of different implementations. http://www.chencustom.com/magwells-1
Very sad. Jim built me a couple of guns, showed me how to build my own, and basically taught me how to shoot. I'd lost touch with him over the last two years, but he was very healthy last time I saw him, or seemed so.Jim Garthwaite passed away last week.
He built two great guns for me.
