Hey I just got a 629 Classic with a 4" barrel,but you can not pull the trigger or pull the hammer back without pulling the cylinder release back towards you all at the same time,also when you use the cylinder release to open the cylinder it kind of clicks when you push it forward. I took it to a gun shop but after messing with it for two weeks he can't figure it out,said to send it to S&W....he also compared it to another 629 that he had and he said it all looks fine???Was wondering if anyone had any ideas...Thanks Robert
