The firing pins are free floating, the hammers aren’t pushing them but the enlarged hulls on my reloads cause the rims to catch on the pins on closing—they don’t fall in like a new case. It occurs if I’ve been carrying the gun open over my arm and the pins work their way forward. Just to fire the gun, reload, and then close is no problem. Irritating! I do know that most of the problem are those darned Cheddite hulls, they are terrible. But still a simple cure would be if coil springs could be added to the firing pin.
