My thoughts my or may not help ya PJ. I'm no fan of long barrels. I DO like the Huckleberry Rig as displayed by Val Kilmer as Doc Holliday in Tombstone. I also like the Skeleton rigs, but most of the Skeleton I'v seen were too vertical. Were I to be using a Huckleberry, I'd have it made for a 3 1/2 inch barrel SA with Ejector. At most a 4 3/4 inch barrel. Of course for myself, it would be made to fit one of my custom 3 1/4 inch Navy pattern .44 Snubbies.
Good luck in your quest. Should be real FUN!!
