Two good comments (not mine, I admit):

The origin of this style of shooting is Israeli intelligence Mossad. In the mid 1970s they sent an assassination squad to Europe to avenge the murders of their Olympic wrestling team, They were armed with mdl 70 Berretta 22lr pistols with special low powered ammo, just enough to RELIABLY cycle.. They shot from point blank range, carried the pistols with an empty chamber and at the last second, pulled back the slide to chamber a round. this is more easily done with the pistol held horizontally (try it). since no aiming was required, they simply shot from this position. They never failed to kill, (although they did get a wrong guy in Norway once).

The real reason and history the "gangsta grip" was originally developed was because the crackheads who used the weapons often confused the mag release with the trigger. By holding the gun sideways, they would save themselves the embarassment of dropping the clip out of the gun. Its sort of a "darwin thing" in the hood. Only those that learned the gangsta grip survived to pass their genes on.
