All joking aside, after having my truck stolen (and luckily recovered) last year, I quickly nixed the idea of a "truck gun" for myself. I'm just not comfortable with the idea of a gun of mine being in the hands of someone that is low enough to steal my truck and possibly being used in another crime later. But, that's just personal preference.
Yeah. That's the same reason I stopped leaving mine in the console it either goes with me everywhere or stays home.
