I have a 2008 S&W Product Guide that shows a 629 Carry Comp (Product code #170279). Has a 3" barrel with fixed rear sight and adj orange dovetail front sight with port. Checkered wood grips that look like Eagle boot grips. Does anyone have this revolver? How do you like it? Does it have the internal lock? This revolver is from the Performance Center. I am very intrigued by this revolver. Might look for one in the future. Any info is appreciated. Thank you...
