Shamrock
Bearcat
Bought new at gun show. Loaded cylinder which then would not close. Took out one shell and closed with a little fiddling but trigger did not move and neither would the cylinder. Closer inspection revealed recoil shield surrounding firing pin sticking out a little and catching on the rim of the case which prevented cylinder rotation. Called Ruger customer service and they contacted UPS who picked it up the next day (a week ago). Anyone else had this problem? I expect a satisfactory resolution will occur.
