Dixie and Cabela's won't ship to me because I'm in Massachusetts and, you know, think of all the evil things people have done with replica black powder revolver cylinders.
The Pietta cylinder is a tiny bit longer than a Uberti. Just enough to make it too tight to fit in the frame. I can put a Uberti cylinder in a Pietta, but there's too much barrel/cylinder gap.
Joe, and others, you're right. I can't understand how I completely missed it! I'll just use what I've been using in every other such case.....old age creepin' in.
