Better to have it... and pay top dollar for it and its permit, and perhaps buy a good gun safe or a triggerlock, and keep practicing your marksmanship, and keep it clean/oiled, and don't let the ammo get too old, and maybe practice getting at it quickly, but don't keep it loaded if you have kids in the house, and carry extra liability insurance in case you're so scared unlucky as to actually hit someone without killing them, and be resigned to always being on record with the police & other authorities as a gun owner whenever your license plate is run through their computers, and maybe the Homeland Security databases too, and can I take it in the car with me when I travel, and will I feel comfortable traveling by air and living without it at my destination... and am I forgetting anything else?
