I've seen several times that it has happened. The round fits poorly in the magazine, but it can hang up in the extractor as it is shoved in, and there is just enough space on the primer for the pin to strike it. since the 9 is tapered a bit, the rim is actually only about .9m smaller. Not even a full MM difference in the diameter at the rim, in fact, it might be that some handguns would hold any 9mm round in place behind the extractor and allow it to fire.
