I'm calling the double ejection RP9 disease. That is the the first modern gun I heard of exhibiting the behavior.

As for the malfunctions, not everyone's hands work the same way. For example, I cannot understand how anybody can get slide bite or hammer bite. It goes contrary to what I was told as a kid, "keep your extremities away from the moving parts". How hard can it be? One style of grip does not work for all guns, same as one driving style does not work for all cars and SUVs. The 380 EZ does not work for the OP's wife with the grip she wants to use. It happens. Sometimes it can be fixed with training, and sometimes it can't.

Shooting left with an unfamiliar gun? Who on this or any other gun board can honestly say that has never happened to them.
