I don't wanna mince hairs here, but in order to get it to fit into an AR compatible format, they used a different casing. I has a longer profile, but uses the same loads, the same grain tips, and executes these with the same velocities and penetration. It's the same shit, different skin.
As to whether or not a living human bean could handle the recoil in a revolver setup (what it sounds like you're going for), yeaโฆit's got comparible kick to a 44 magnum in a 10" barrel. It's got far less diameter to throw downrange, so the burn is gonna be much more efficient with the longer case, and you can load it lighter if you honestly plan on using it for self defense (just up your grain to 200, and enjoy the balance of a shot hitting your assailant at 1600fps with way hilarious knockdown potential).
I'll be completely honest with you however, you're wasting your money if you're just looking for a self defense gun. It's gonna be much bigger than a shorter barrel 357, it's gonna costs far more than most revolver offerings; you could get a very lightly used 44 magnum for substantially less. It's gonna be heavy on your hip, be a bitch to sit down, and ultimately you'll find yourself wearing it less and less. I'd just get a concealable 357 in a lighter frame, and keep some 38s available for range time. The whole point of going for a maximum is for the flat trajectory across long distances. This is the biggest boon, and one you wouldn't even get to utilize since you'd be shooting at much closer distances than what it was designed for. If you feel a 44 isn't enough protection, go to a 454 instead. You'll probably be paying comparible prices at that point tho.
