First: The only sure way to win in a violent confrontation is to avoid the confrontation altogether. Second: A gun is a tool of Last Resort. It is not to be used to resolve petty arguments etc, it is only to protect innocent life that is in imminent and immediate jeopardy. You have not been deputized and don't have an obligation to put yourself in harm's way to stop petty criminals. Let the police do their job, and you do yours! It is good to help others and protect life but learn where to draw the line. Depending on what research you believe, average deadly confrontations occur in 3-10 feet or less. Consistently putting that target out to 15 meters (45 feet) is impractical and probably not a great use of your training time or resources. The law is up for interpretation. Only after the incident occurs, through the paradigms of two arguing attorneys in consideration of presented evidence, does a jury of 12 peers decides your fate. Justice is blind, as they say. Learn your gun laws. Gray Man Theory: The Art Of Blending In During Disaster. The gray man theory is a way of disappearing into the crowd so you can move unnoticed when disaster strikes. The idea is that you can conceal your preparedness by blending in with the crowd before or during an emergency. Shooting to wound refers to attempts to use a firearm to harm someone without killing them. It is controversial since the unpredictable nature of firearm wounds could result in the wound failing to incapacitate the target; it may accidentally kill or miss the target, the latter presents a risk of unintended casualties. Limbs are one main area often targeted when shooting to wound. However, limbs are smaller and can be moved faster and more radically than the torso, so the option of shooting to wound is generally viewed with skepticism by law enforcement in the United States. “Printing” refers to what the act of the gun physically imprinting its outline on the clothing is colloquially called (example). For example, a “printing” law would make handgun imprinting illegal. “Printing” is like hiding behind a curtain and anyone being able to tell the shape in the curtain was a person. Hollow point bullets are a more expensive round and best used for self defense situations, and loaded in your Every Day Carry (EDC) defense weapon. They are also best as your home defense weapon. Full Metal Jacket (FMJ) rounds are best used for range shooting since they are much less expensive. Full Metal Jacket (FMJ) and Hollow Point (HP) are the designations for the two most common types of ammunition fired from metallic cartridge firearms. Full metal jacket ammo is typically used for target shooting and plinking while hollow point ammo is considered the gold standard for self-defense. As ridiculous as it may sound, someone spotting you by seeing the outline of a handgun under your shirt — printing — or when your cover garment rides up to show a part of the firearm can be construed as brandishing. You shoot to STOP THE THREAT is about all I can tell you. If you do find yourself in a defensive shooting you will shoot to stop the threat, that may be two shots, it may be ten.
