On her first try with the EZ 9, my wife and her friend had trouble with it. I told her to be sure she is engaging the grip safety. Next day, no issues. No change in the gun or ammo, just technique.
When she came home from her vacation I cleaned the pistol and took it the the range a couple of weeks later. No problems at all for me.
My lone criticism of the EZ 9 is that it feels nose heavy. Both of us think the EZ 380 is just all around better, and easier.
She was hoping the EZ 9 would be just like the 380 but in 9mm and it is not. Everything is less EZ than the 380.
So I get a new 9mm
