Just traded for a 29-3.It has a 3in.barrel and a non fluted cylinder and I just fell in love with it.While checking it out I noticed I could push the hammer off with my thumb when cocked.It takes a good bit of pressure but I can push it off it stays cocked if I rap it as hard as I can with my hand,its only with a good bit of pressure from my thumb that I can uncock it.Would this be something to worry about as everything else seems like new.Also I'm not sure if the springs are factory.The trigger breaks consistantly at 2#10 oz.in single action.Would a too weak rebound spring be the problem? thanks in advance for your opinions.
