That's a smoking deal for .45. I only used the Lawman ammo as my example because that was what Ammoman had in comparable loads for both calibers. I don't think that Lawman ball is anything special, but it's relative rarity makes it seem that way and it does tend to be overpriced.

Agree with your points, although I don't feel under armed with a 9mm. My big issue with the .357 SIG is that higher velocity or energy always come with a price, and the biggest price is speed on follow up shots. If I can run, say, a 9mm Glock at a certain speed, I will be measurably slower with a .40 or .357 SIG out of the same sized gun. To me, speed on follow up shots against the same target or multiple targets is more meaningful than a relatively small improvement in terminal ballistics.

I can actually run a steel frame 1911 faster than anything else, but since non-.45 1911s set up for fighting are nearly nonexistant, there aren't any common guns in higher energy cartridges like .357 SIG for there to be a meaningful comparison. I'm not aware of any production .38 Super that is made for anything other than competition, so again there isn't any direct comparison to be made.

If you want penetration on auto bodies, one of the best things commonly available is 5.56 M855. I know that the gun writers like to talk about how it fails constantly in combat (which is a substance that resembles what comes out of the south bound end of a north bound bull), but it cuts metal as well or better than anything short of a true AP round. I've seen it cut 5/8ths of an inch of rolled steel at 500 plus meters out of a 14.5 inch barrel. 7.62 sniper ammo out of a 24 inch bolt gun was bouncing off that same plate without leaving a mark. M855 will ventilate an automobile and whatever is inside it in short order.
