I was at the range about 2 weeks ago and attempted to do a 5 with 50 drill with both my SR40 and 40c. I had a problem with the trigger not resetting on every shot with both models while shooting one handed. No malfunctions when shooting two handed. I was shooting all the same ammo. Winchester white box 165 FMJ. Any ideas? Could it be something I was doing wrong like not releasing the trigger and allowing it to reset? It was pretty much happening at the same rate for both guns and left and right hand.
