@Dapper Dave In defense of the guys advising caution, let me share with you that I bought a Sharptail, and brought it to Doc Noper, who is an established cowboy shotgunsmith, and he took one look at it, gave it back, and said "whatever those crazy steampunk internals are, I'm not messing with em." Ended up sending mine to Longhunter before he got out of the business. Not in any way questioning your gunsmith, but reinforcing that these guns are very unique. Hope the whole thing goes smoothly!
