The thing about weapons is that they aren't for everyone. Not everyone has the survival mindset ingrained within them. I like to think that everyone has a strong survival instinct, but unfortunately it isn't true. This is the reason for the military and the police. They can go bad sometimes, but the purpose is for protecting those that cannot protect themselves. A firearm is a tool, same as a knife, ax, or even a circular saw. If you are afraid to use them, the results can be more harmful than useful. If you understand the purpose and practice in the use of, you still have to prepare yourself mentally so that you have no overwhelming fear. Start with a 22 long rifle caliber rifle. After practicing with that and becoming confident in training and understanding, you should move to a pistol chambered in the same caliber. If you grow confident in your safe handling and use of the pistol, you can try a centerfire pistol. If you feel that it is not to your liking, you can stop moving up in power. A 22lr rifle is a fantastic subsistence weapon. Small game is readily dispatched in a humane manner and can be necessary for survival. It can also serve as a defensive weapon, if needed. Do not underestimate the lethality of a 22lr, it is just as dangerous as a higher power cartridge, although it has less stopping power. In the right hands, it can be extremely potent and deadly.
