Hey everyone, recently having a discussion w a few buddies over the penetration advantages of 45 acp vs 357 sig. Particularly through something like a car door/windshield etc... your insights would be appreciated!
I agree, if the car is moving. Not all cars/trucks are moving, and are often used as cover. It helps to know if your round is likely to defeat that cover, if it should arise. I know I would prefer to be behind that engine block/wheel, than just behind the doors.Any time spent shooting at a car is, in many (most?!) cases extremely important time that is much better spent attempting to get out of the path of a 4,000-pound machine that is just really not going to be stopped by a handgun.
9mm or .45 FMJ may or may not penetrate the steel. Most likely go through one side but not the other.
I doubt that either the .45 ACP or the .357SIG would have any trouble getting through a car door since it is typically 20 gauge mild steel -about a millimeter thick or four hundredths of an inch. Quite frankly, I think that windshields are harder on bullets than the thin steel found in car doors.
I think the old soviet 7.62x25 tokarev round would leave both the .357 sig and the .45 acp in the dust.
