You gave the exact test I'm suggestingNo. I have a G26 and a PT99 that I have never had a problem with. I have taken both of my daughters to the range and watched them limp wrist them while shooting. I corrected their grip and that was the end of it. I'm not worried about that being a problem for me.
Us Walmart Berets never seem able to duplicate the malfunctions on our own. I wonder if that is because we can't simulate being wounded. But hand the gun to your young daughters before their training was completed, and watch the malfuntions
The possibility of being wounded to the extent of shooting like a newbie may be in same realm of possibility as needing that 2nd back-up mag
