.....Want to hit the target? Never "shoot from the hip". Hollywood invented that. Looks good on film, but you miss a human size target over 10 meters.
Not completely true. Hollywood didn't invent it; it's actually part of the qualification drills for police. Most drills teach to shoot from a two handed grip and stance, HOWEVER! Since most true gunfights occur at LESS THAN seven FEET (much, much, much less than ten meters) most drills are at much closer range.
What Hollywood invented was the idea that handgun fights occur at longer ranges. They're up close and instantaneous (over as soon as they start)
The "hip shot" drill in this case revolves around a more realistic scenario: the attacker is within reach of the defender and the defender is using his/her weak hand to push away the attacker while drawing and firing.
Is it dangerous? Absolutely, but so is a gunfight. Especially if you haven't trained for reality.
