You need to be 100% certain where you stand legally before going for your weapon, never mind before you pull that trigger. But if you have been doing your training and thinking things through and understand your laws(not just learn them enough to pass the test). You need them verbatim. You will pull the trigger, you will phone the officials and you will phone your legal advisor and the insurer to pay that legal advisor. But you will be alive to manage that. You will not be the one climbing in the ambulance and that is the main benefit.
There is a saying don't bring a knife to a gun fight. Criminals don't ring you up to tell you what they bringing. So bring the best you have. These self defense pepper balls, batons and knives are more dangerous than guns. They will escalate the situation with a much lower chance of winning.
No one should know you have a gun. Grey man concept for me. I can talk here relatively anonymously. But the staff on the farm don't know I carry, In fact my parents haven't realised even though I see them weekly. No one must know about it until you need to use it. That is why it is tricky in tight cycling gear. Hard to hide the gun from printing.
It absolutely irritates the daylights out of me when I see people in public with a 9mm or 45 on the hip loud and proud. Those are targets.
Training is key. See too many people blowing loads of cash on optics and lasers and lights instead of ploughing that cash into ammo at the range.
It is an interesting one. We have a farm swap set up. If we need an animal euthanized another farmers comes to do it. I go to sort their animals out. So the staff don't think we have weapons on site.
The fist few times you do it, it is a little emotional. Especially a cute cow and you walk right up to it, look it in the eye and end the pain. But after a few times it does get easier and easier. You do desensitize yourself very quickly. I had to put down a donkey a few weeks back and if I had to do that one the first time it would have wrecked me emotionally. Now it was not too bad. But I think going from nothing to a human would put a lot of people in a very dark place after the fact.
That is why no one should know you have it. If they know what they doing you will not know someone you are riding with is carrying. Neither will the bike jackers.
I would be more concerned with people carrying less lethal options like knives and batons.
If the perp pulls the gun on you it is too late for talking. They didn't bring a gun to talk, neither should you.
Honestly training with guns is a heck of a lot of fun. I get a lot didn't enjoy it due to Army service, but for some of us it is just relaxing. For me to pop into the range after a stressful work day is a treat, you quickly forget work and get home relaxed. I have signed up for a full year of training with a monthly course and honestly I am super excited to learn the various aspects.
The mrs is thankfully supportive so I have an ammo budget each month for playing and training on the 9mm. It has no effect on the hunting ammo budget. But training is super super important. Like riding a bike, you can't do nothing for months and expect to klap a big technical ride. You need to stay bike fit and if you carrying you need to stay gun fit and alert.
