Hi: The only factory ammo that I fired were a couple Boxes of Hornady but they were all shot S/A and all fired on the 1st pull. It seems to be a D/A Problem. I believe that the S&W ignition system has a Problem with the extra heavy CCI LR Mag Primers.
I may load some Reduced Pressure Rounds with Standard LR Primers and see if the Problem Goes away. I was Just Curious if anyone else had a Similar Problem with using LRM Primers in an X Frame.
