Shea Grey, I guess I need more spelled out. Please expound on the security first. What should one do to stay more protected in our own homes? I understand arms, but there is more to it than that. I would appreciate suggestions. Thank you for the help.
(Not stepping on Shea's toes, he'll probably give more detailed stuff but just throwing this out there)
Strengthen Doors.
Lock things, make sure the locks work.
Understand your property, how to defend and/or make barriers or funnels so anything approaching has a very narrow field to maneuver in. (This makes it easier to kill what you may have to)
Understand your arms, get used to them, how they feel, how much they weigh, how loud they are without hearing protection.
Practice, practice, practice with your arms. Make sure you know how to fix them and have spare parts. Make sure you have spare ammo (LOTS).
If you're in good with neighbors talk with them about defending your AO.
Make sure your family is aware of what to do when/if something goes wrong; i.e. the wolf is at the door.
BE ALERT and NOT AFRAID; confidence may win some situations so you can live another day.
Keep it simple with your arms; common calibers and gauges. I'll assume from your question that you won't be getting anything to exotic.
Mindset, mindset, mindset; be prepared to actually pull the trigger while aiming the working part of the gun at a HUMAN. Paper targets are one thing, a living breathing 'human' trying to kill/harm you or your family is something different.
Know your laws or be prepared to S.S.S.
