Back in the day, we called it "weak side" and "weak hand". With the pistol in the WEAK hand, at a 45 degree angle to the ground, at the sound of the beep the shooter will engage the target with two to the body and one to the head. WEAK hand. Weak side.
Now, we are calling it "support side" and "support hand" BS. It is WEAK and needs to be called like it is. WEAK.
