Many of these are unrealistic weapons. What is it good for? What is the purpose? Because it looks cool? These big pistols--where do you put them where you can get at them?
I used to carry in civilian clothes for work. I worked where we were always looking in garbage cans for bombs and anyone I walk past I still look for weapons in the usual lumps. It's hard to conceal a pistol. And it's hard to conceal it where you can get at it quickly. We used a hi-ride pancake in civilian clothes and you have to be a yoga instructor to be very smooth with it--that's with a suit jacket. With the usual state-trooper sweatshirt you would have to be a ninja. Screw the 10mm--I carry my pistol in my front pocket. I have thousands and thousands of practice rounds through it because ammo is cheap for a .22. If you don't shoot 50 rounds a week through your weapon you shouldn't be carrying it. I don't mean aiming--I mean pull it out and start shooting and hit what you are shooting at from 10 or 20 feet. Muscle memory. I think most gunfights happen at 7 feet. I didn't carry a .22 on duty, but on duty you have a different responsibility. Now my responsibility is personal protection. I want to have my weapon available instantly and I want to be able to empty the magazine into something 20' away, which I can. Not because I'm a bad-ass, but because I shoot a box of CCI Stingers through it every week and it's as natural as brushing my teeth.
At home the 12-gauge is king for security. At home you need the final solution power, not the escape power.
If we need to hunt, which we don't, it would be rabbits and squirrels. I don't need a big rifle for that.
If it's armageddon--well, that would be the 4th weapon(s) and the least expected need. And I am prepared for that as well.
