Had an acquaintance in Las Vegas, lo these many years ago, who got drunk, got PO'd at his little pickup truck, and dumped a mag into the hood of the truck. One of the higher end .25 autos, IIRC, but might have been a .380. Hired my mechanic friend and I to fix it. Only two rounds actually penetrated the thin sheet metal hood. One of those hit the carburetor and just barely cracked it. I learned a couple of things from that. Need a more powerful gun, though technically it could be considered a mission kill. Engine still ran, but was leaking fuel, would have eventually caught fire. And don't drink when you have serious shooting to do. And since you never know when that may be, maybe you shouldn't drink at all. Dude was a rectal orifice frequently when he was stone cold sober, so...I read recently that statistically the lowly .22 is the caliber that most often ends gunfights. Why? Because it's the most common caliber and most people stop fighting after you put the first hole in them. Makes sense. Naturally I'd prefer a Magnum or a .45 ACP but if that's not handy any hole puncher is better than none.
