Isn't the 357mag an outdated POS loved only by old guys with shrunken genitals? You know, the kind that post pictures of their revolver with a knife lying on animal skin?
A 4" barrel in a pistol is equivalent to a 3" barrel in a revolver. The 40sw pistol can do 155gr @1250fps. Can a 3" revolver move a 158gr pill that fast?
I can't see any reason to lug around an anemic 6-7 shooter anymore.
Ballistically they are both plenty powerful enough for defensive purposes. And, I'd choose my Glock 22 over my Security Six every time for personal defense.
That said, a 3" 357 revolver easily has the nuts to start a 158gr at 1250 plus.
Here's a 2.25" SP101 starting a 180gr at 1260 fps.
