Speed, pure and simple. It allow one to get a round away significantly quicker than a more traditional shooting position. That said, mastering it is Hard! And it’s a short range thing only. There’s and old video of Bill Jordan holding his strong side hand palm down with a pingpong ball on top of it. He then moves that hand, draws a model 19 Smith from a duty holster and hits the pingpong ball with a shot before it hits the ground
. That boys and girls is fast! Jordan advocated all police officers master shooting from the hip for targets out to 3-5 yards noting that a first shot on target usually wins the fight. Makes sense, and even an old man like me can get a shot away from the hip a lot quicker than any other way (based on results using a shot timer). The trick is to be able to actually HIT with that first fast shot.I’ve been practicing this a lot at 3 yards with my 3” EMP.(that’ll make you humble
). In an SD situation a few tenths of a second can be critical, so I’ll continue working on this. However, just about the time I think I’ve “got it” I’ll miss several in a row.
. YMMV
