Her are some pics of a carbine I'm making from a Pietta pistol and a 31 cal muzzleloader.
Barrel is 28" long. I had a friend machine the barrel threads for me.
I cut down a 44 cal cylinder and lined it for 32 S&W long.
Has a Kirst konverter ring. Still needs a lot of work.
I think I'm going to make a longer rammer and get a carbine triggerguard someday.
I apologize for the poor quality of work, but all I have is a hacksaw, file, and a drill press.
Happy New Year everyone!
