When you guys train at the range, do you actually train for center mass or try to go for headshots or possibly where the limbs would be?

The more in the head, the better. Make them stop immediately. Hitting the heart or center of mass can still allow the perp to press a trigger and keep killing for many seconds. A center head shot can make them drop right now and stop being a threat.

Two to the body and one to the head, at least! That's how we trained!

Muscle memory. Two to the heart and one to the head.
