I've got a Uberti American Buntline that has been cut down to 5 1/8". The problem I'm having is that I'm not sure of how to cut the new front sight slot? It's an original style with a rounded bottom, no dovetail. I could put it in my Smithy sideways and use a keyhole cutter on the side (top) of the barrel, but is that the best way?
Thanks,
