I would trust only Dan at Giacomo's for this job. I made the mistake of trying another "un-named" gunsmith to do the job, and it was a mess. Giacomo fixed it right. As I recall, it cost me right at $400 at the time to have both side ribs re-soldered and the barrels blued. The blueing is the most important part of this job. The barrels cannot be hot dip blued, or salt blued, as this will attack the solder on the side ribs and you have to start all over again. The side ribs are not silver soldered!! Giacomo's will do it right.. Just my experience... Dan Thome (Trap2)
