I have a full size Sig P320 RX along with a spare carry slide and two other frames (carry and compact). I updated mine by installing a lighter trigger. It was a flat trigger with low mass, so the odds of it going off if it were dropped on that one axis in a million were lowered. I don't drop my weapons, and don't plan on starting, but I did take care of this concern myself. It is without a doubt the finest striker fired pistol I have ever shot.
