What weapon do you keep in your truck? Granted my shield is always with me but I was thinking of buying something to just stay in the truck. Nothing expensive just something that would have a little more range than a shield. I was looking into a keltech Sub-2000. Not to expensive but adds a little more security to my truck than the shield I carry. I don't want to keep my AR in my truck... To much money and to hard to hide. Any ideas?
