Looks like it's already been covered.

Just for the sake of redundancy....LOL

Random thoughts...

My carry gun first and foremost MUST GO BANG EVERY TIME I PULL THE TRIGGER.

Second, I must be carrying it.

I want it to make BIG HOLES. I must be carrying it for it to make any kind of holes at all, so it must not be suited for making holes in the desk drawer, the glove box, under the seat of the car or else where other than as big a holes as possible at what ever is at the end of my hand.

An unknown attacker outside your home is not likely to give you warning and wait to see if you have a gun. Ambush as in the rest of nature is most efficient and as such most likely. You absolutely must have enough bare hand defense capability to give you the opportunity to get out your gun. Don't get killed trying to get out your gun so you can be a "knife to a gun fight" dead wise ass.

Brings me to a very enlightening little game we used to play.

Set something like bowling pin or a white water filled milk jug up.

Now stand as far a way as you feel comfortable justifying to the law you killed that man with a knife with your 44 mag, 45, what ever.

Now have your patner pace of an equal distance straight behind you.

Now with your weapon in normal carry mode, maybe your hands in your pockets too if it's cold weather, he says give me you wallet and runs to "tag" you on the back.

Let's see you draw that "self defense" carry monster weapon and knock off that bowling pin or blow the milk jug.

I think you'll find the results interesting.
