It is sad what is happening into our society but if you can by any means can disable the burglar its a much better way than killing.
Exactly, the idea is to protect your property from theft and trespass, not to take revenge for the robbery they were prevented from committing as a consequence of killing them. That still carries a high risk that they will be killed, of course.
I feel like it would ruin my life to kill an intruder. The trauma of shooting someone, the legal fees, it would be horrible. However during the event the only thing that matters is winning the fight. I have had the displeasure of getting into gunfights on three continents now and I know how to shoot back. But it is illegal (in my state) to kill someone to protect property. The only time you can use that gun is when "You or someone in your immediate presence is threatened with death by an assailant".
That means if my gun comes out someone is going to get shot in the chest. The idea of wounding an intruder or shooting for the legs is an absolute movie fantasy. If an assailant has chosen to risk your life you do not play games. You do not yell "Freeze!" or threaten to shoot them, you shoot them. Follow these best practices if you are considering joining those who carry everyday.
1. Budget.
It will be very expensive to carry. The gun needs to be a good one that you can bet your life on. $1000. You will need to join a club to train. That will be maybe $400 per year. You will need to get a background check for the gun, another for the CC license, and you will likely need to attend a class. All these will run about another $100. You will want to get insurance to cover yourself and that will cost about $400 per year. Ammo for training will run about $600 per year minimum. That is only 50 rounds per month. Better to budget 50 / week. Holster, spare mag, cleaning kit and miscellaneous accessories is another $100. So that should get you started for your first year at about $2600. It ain't cheap.
2. Train with the best.
Most clubs have three-gun, CC, and other training opportunities to improve your skills, pay for them. Listen to your instructors and always:
Keep your gun on you, chambered and safety off. On you mens ON YOU, not in your car, not in your purse.
Always shoot for the center of mass. Not the legs, don't try to shoot the gun out of his hand, shoot right for the center of the chest.
Stop shooting when the threat is over. If you keep shooting because you are mad or whatever, then you are going to jail for murder.
Plan your defense at home. Mark out all the distances you might be fighting from in your home and set your sights accordingly.
Do ballistics tests with your gun to determine the best ammo. Under and over-penetration are problems.
3. Watch videos.
This is a weird one, but you can learn much from watching the successful and failed attempts of others to defend themselves. Check out this youtube channel for an example of what I mean.
