I had one like that, first Cimmeron sent a 44 colt 60 RM with a 44 cylinder and a 45 barrel, couldn't figure out why my groups were so large! They replaced that straight away with one that rubed everybit of bluing off the engraved part of the cylinder. The alighnment pins had upset the metal of the water table just enough to rub. A little work with a dremel took care of that and a rust blue fixed the cylinder. The pin wasn't bent, and I might have sent it back except for the accuracy was better than any gun I've ever owned.
