I just got my little 432PD and got to shoot it this last week with a small problem. Two or three rounds per cylinder won't fire due to the light firing pin strikes, barely any mark on the primers at all. Tried two different brands of ammo with no difference so I'm confident that it's not hard primers. This is a brand new gun so nobody has "fixed" anything in it. Not being a Smith guy at all, is there anything to look for before calling S&W to ship it in? Thanks all.
