I've got this Cattleman II that's a factory convertible from Uburti, i.e., it comes with two fitted, same serial numbered, cylinders, one .45 Colt and one .45 ACP.
Very nice.
Thanks. Safely holds six, due to the newer design on the Cattleman, so there goes that rationale for preferring Ruger to the more authentic Uberti.
Rugers are still likely a bit stronger, but not so much for the New Vaquero.
