I know there are various mechanical problems that can cause fail to feeds, but what all can cause fail to exits? I went to the range today with a friend that is a noob at shooting. The second round he shot out of my XD failed to eject. Assuming he was limpwristing, I showed him a better grip, and no more problems the rest of the day. I have NEVER had that gun jam on me. Is it safe to assume that the jam was caused by limpwristing? Can anything else cause a fail to eject? I've yet to see a handgun FTE with someone that knows what they are doing shooting it.
