Glock. I looked into a few options when shopping for a beater/car/truck gun, I ended up with a G19 over a CZ, SW autoloader, P series ruger, and a few others for several reasons.
1) I dont like glocks. If it does end up stolen, I'm only out the money, instead of a pistol I
like or would grow on me (S&W, CZ). It would also be easily replaced with another glock that I wont care much for.
2) Its already ugly, so if it gets beat up more and ends up with more wear on the finish than my EDC pistol, its no big deal.
3) The finish is dern near bulletproof, so it'll hold up to neglect a lot better.
4) Really doesn't matter in your case since this is an auto vs revolver debate, but mags are easily found.
If you have a place in your truck where you can mount a holster, where its out of sight and easily accessible, I'd suggest doing so (
my old setup). A fobus works well, I used a blade tech because I hung a light on mine (I dont like the fobus "light gun" holsters). Not only is it more secure* than it would be in a door pocket or console, it will keep the plastic sights from getting beat up. I recommend steel sights, at least a front (my rear sight has held up pretty well, however my front got beat up pretty quick). Don't keep it in the glove box with your registration. Not only could it result in a nervous LEO if you get stopped, but if you
need it, its on the other side of the truck.
*By more secure, I don't mean less likely to be stolen. However it is less likely to end up flying in the event of an accident, and you wont have to worry about anything else you keep in that compartment getting in the way of your draw, or hooking the trigger and putting a hole in your floorboard.
