Hey, I need some advice here. First time out with my new S&W 442 and after a few cylinders I had a problem. I was shooting UMC 130gr ammo and with a full cylinder it was just cycling with no firing on live ammo. I emptied it and found that the firing pin was still coming out so I am confused. I tried those rounds again later and they worked. Any advice before I contact S&W? Try some different ammo or do you think it is a gun issue? Not good to not have confidence in your CCW choice.
