I would be extremely surprised to find anyone conveniently located in my area who works on these sorta of guns. Hell, I can't even find a good 1911 smithy in my area. So, pretty sure shipping will be involved somewhere.

Indeed! When that didn't lead to an answer, I opted to use my internet skills to reach out to other gun nuts on the internet to see if some internet-based collaboration might lead to an internet-based resolution!
