Hollywood loves guns (in the movies) but as one blogger points out, they don’t know much about how they work in real life:

Poor grip

I cringe every time I see a leading lady “teacupping” her handgun. Teacupping is when the shooter’s dominant hand is too far down on the backstrap of the gun, and the support hand is just an open palm that is cradling the bottom of the dominant hand. Think, a teacup placed on a saucer.

“The problem with this grip is — it’s not a grip. As soon as a shot is fired, the dominant hand will rise off the palm of the other hand, and usually the shooter’s arm will rise too. You’ll also likely see a wrist break, and it’s not unusual to see the shooter tilt her head back during the recoil, because she’s reacting to her arm and wrist moving back toward her face. Ultimately, she must re-establish her grip after every shot.

“This is a very unstable way to shoot (and a great way to have the gun fly out of your hands) as opposed to a push/pull grip. With a proper grip, you keep your dominant hand high on the backstrap and wrap your support hand around the fingers of the other hand, with your index finger held up tight under the trigger guard. The sides of your hands and thumbs should align, almost like you’re holding a blade of grass between them (Remember when you were a kid, blowing on a blade of grass to make a whistle sound?). Thumbs should be straight or pinning one down with the other; that is a personal preference,” said Suzi.
