Sorry, I let my frustration get the better of me. Thanks, Jim, for your reasoned response, and the rest of you too. The slam-fire concern is moot, as I will likely never reload for it.
The info about the inertial fire may, in fact, be suspect. I remembered that this is a military small arm, so the designers likely took into account the arduous conditions in which it may be used. Weapons get dropped, or jarred loose from the holster routinely, I suppose.
