Seriously. Wouldn’t it better to drop it like it’s hot? Or do you really need to hang onto that unknown number of “extra” bullets for another tactical reload? Remembering that most shooters in a self-defense situation shoot until they’re dry, as inadvisable as that may be. (Ideally, you should shoot until the threat stops; no more, no less.) Keeping in mind that your free hand should probably check for ammo BEFORE you jettison those “spare” bullets. Which would necessitate two weak hand trips to the ammo belt if you were pocketing the semi-played mag. And taking note of the need to keep the gun unloaded for as little time as possible.
