For Christmas I got 3 CP revolvers; A Uberti 1861 Navy .36, A Uberti Colt Dragoon 1st Model and a Pietta 1873 cap & ball version of the Colt Peacemaker. My problem is that the cylinders stopped revolving to the next shot, on the Dragoon, and the 1873. The 1861 Navy preformed flawlessly (In fact I was surprised at the accuracy!) Even after cleaning, I'm seeing the same problem with the cylinders revolving. Sometimes they do, and sometimes they don't. Can anyone please give me some insight as to why this is happening? Thanks in advance!
