Probably. Definite, maybe. Most of the time. Some do require some fitting. You can also get single notch Col style base pins for Uberti from VTI Gunparts. Although, I would suggest a Hacksaw and some 400/600 grit wet or dry. Cut off the last 3/16th of the base pin, then chuck up the base pin in the drill chuck and touch the rough edges with a file the polish. There after, seat the base pin all the way in. Cost ya 2 bucks for the sand paper. Everybody has a hack saw (right??)
