Owning any firearm means you have the responsibility to keep it out of the wrong hands. You won’t be carrying it all the time.
I’d recommend consideration of a gun safe with the capacity for at least 24 long guns and a dozen or so handguns. Then start to work on filling it up.
I see what you are saying about not letting guns fall into the wrong hands, but what good will my gun locked in a gun safe do me if someone were to break into my house? I’d much rather have the gun in my nightstand drawer.
I get annoyed with people who make specific handgun recommendations as for model or make.
Just because my neighbor really, really likes his shoes is no reason for me to go out and buy a pair in the exact color, model and size.
