While at a recent range session my MP 9 failed to grab the spent shell to eject it. It was about 2/3 of the way through the magazine when it happened. The slide stayed back like the gun was out of ammo. This is the first problem I've had with this gun but re-affirms to me why I like revolvers for self defense. I don't remember ever having this problem with any semi auto I've owned and if it was dark and in a stressful situation it could have been costly.
The gun worked perfectly afterward. Has anyone else experienced this problem with a MP?
