Hello Friends, Just bought a Rossi model 68, 38 sp. A police trade-in, Everything functions great - lockup is as tight as my S&W, timing seems to be good, etc. - when it's unloaded. After I shot the first round the cylinder locked up, I swung the cylinder open, shut it and it shot the remaining rounds in the cylinder, reloaded and it locked up after I shot about three rounds. What causes this, I've heard Rossi has a lifetime warranty, is it the ammo, can it be fixed??? HELP. Thanks, Bernie Well, don't know if I have a problem or not. When I first got the gun I gave it a good cleaning but didn't oil it. After I shot it for the first time I cleaned it and gave it a good oiling. Just got back from the range and put 20 rounds through it without a single problem. I wonder if oiling it made the difference???????????
