Here is a basic handgun defense principle. “RCAT” – Redirect, Control, Attack and Takeaway.
First we redirect the muzzle of the weapon from all body parts. This might also mean that you move your body, not just push the weapon away. Get the line of fire off your body.
Next we control the weapon. Remember leverage! Once the muzzle is redirected, you should get control of either the weapon or the weapon hand.
The third step is attack. An aggressive counter attack is suggested. This might be accomplished with an empty hand , knife or even you own handgun. If you decide to engage with your handgun, just remember, you are up close and personal, do not give your adversary your firearm. Maintain a good weapon retention position while you are firing and watch out for your own arm.
Finally, disarm the assailant. This might be accomplished when the bullet penetrates his chest cavity or after the empty hand counter attack you get two hands on the firearm and dislodge it from his grip.
Practice, practice and more practice is the key. Also do not forget realism and safety. During a violent encounter or combat and activation of the Sympathetic Nervous System (SNS) will occur. The activation of the SNS is often referred to as the “Fight or Flight Syndrome”. It is activated by FEAR of Death, Serious Bodily Injury or Pain. Realistic Force on Force drills utilizing proper protective equipment can create a reasonable facsimile of combat. These drills are extremely important to include in your daily training.
Remember this quote and make this a goal of your training, “To master self-defence so well as to never have to kill anyone…” – Imi Lichtenfeld
