Anything. It’s a 45. Once they realize it’s a 45, bad guys just fall over. LOL

But seriously, even ball works defensively in a 45 ACP...maybe good hollow points are better, but anything 200+ grains and -45 wide, is pretty effective.

Also, no, it doesn’t penetrate well.... it’s a big, slow chunk of plated lead that’ll bounce off of lots of things.....hardwood stumps, doors, thick glass....seen it. Great for soft tissue. Not the best at getting through anything hard to get there or staying on a straight line if it does get through. Just pick a quality HP load that shoots good in your gun, and don’t sweat if it’s a gold dot or hydra shock or critical defense.
