I've read that one of the main reasons the Texas DPS went to the .357Sig is that none of their previous automatics provided the automobile penetration they had when they carried .357 Magnum revolvers. The .357 Sig gives them that penetration.surprise_i'm_armed wrote:IIRC, some LEO agencies use .357's so that they can penetrate the BG's car bodies
during traffic stops that go hinky.
But still, a carbine in .357 Mag is going to be an excellent weapon while probably not penetrating as much as say, a .223Rem/5.56mm.
(I have no data to back up that penetration comparison, but just guessing here.)
