Poster I saw somewhere -

I would
rather go to my grave
never having had to use my gun
than go to my grave
wishing I'd had a gun to use!

(or something along those lines)

People buy life insurance, in case something bad happens to them
They will not buy a gun to prevent something bad from happening to them.

A gun is just life insurance that you can hold in your hand!
