When I was travelling to see my daughter I stopped at their place in Winchester VA. Not sure if its still there was a few years ago. Like walking into an old west gun store. It was fricking neat. I spent a good amount of time in there. I'd love to get a BP revolver someday. Not sure why I wait.
Obviously anything Black Powder they can sell off the shelf, and regular long guns. Pistols they said were a no go to MA. I did not ask about frames, at the time they carried
only revolvers there were no semi's or 1911's.
