Not to side track the original topic, but I doubt the most of those M1 Carbine stories are true. It's almost always someone who knew someone, or heard it somewhere. If the clothing could stop a 30 carbine round from an 18" rifle barrel, a 357 round from a 4"-6" pistol barrel wasn't going to do any better. I suspect that if it honestly did happen a few times, it was either lousy ammo or GI's using the round outside the effective range of the caliber...firing at long ranges when the GI with M1's began firing. Or they just flat missed, got a hit on a thick coat but failed to hit the body inside it.
