Bought a new Rossi 462 .357 mag. (stainless with 2" barrel) and put less than 50 rounds of 125 gr. Golden Sabers and Federal Hydroshocks (.357 & .38+P) through it when I started having problems. The revolver locks up now and then. The trigger will not pull and the hammer can not be cocked. A slight turning of the cylinder by hand frees it up. I also noticed the firing pin stikes the primer way off to the side now and then. Took it back to the dealer. His best bet is the steel in the extractor is bad, not allowing the cylinder to advance properly. Sent it back to Rossi for repair. Guess I'll find out how good their life time guarantee is. Any one else have this type of problem?
