Last answer of the night:
You must be looking at one of those hyper velocity Cor-Bon rounds - Correct. I've been shooting for more than 50 years. I once shot on a firing line while standing right next to the Cor-Bon factory rep. Some pistoleros think that the faster they can get a bullet to go, the more energy it's going to dump into the target. I say, 'horsefeathers'.
I'm a pistol instructor, an RSO, and a (former) worthy competitor. What I usually see is a lot of pistol shooters who've done an excellent job of, 'over-gunning' themselves. Never shoot a cartridge whose recoil you cannot easily control and absorb. These ultra-light, high velocity bullets have a very hard sharp recoil to them; they often induce flinching in gunmen who are old enough and experienced enough to know better than to use them.
If a pistol/cartridge combination is too much for you to repeatedly fire accurately and easily then it's not the right combination for you. With the exception of very short (3" or less) 45 ACP barrels I always use 230 grain bullets - Often hardball, too. 230 grain 45 ACP pistol bullets got American fighting men through two world wars, and several major conflicts. With the (possible) exception of the people who got shot, nobody ever complained!
The reason I like high quality hardball is because it'll punch right through heavy Winter clothing without stopping like a JHP round will. The usual flap revolves around the over-hyped idea of, 'excessive penetration'.
I've been shooting for more than 50 years. During all this time I know of only a very few instances of authentic excessive penetration which caused harm to someone else. I know about plenty of clean misses and peripheral hits continuing to fly on through and do some sort of damage; but, almost no authentic examples of so-called excessive penetration AND harm to another.
Once they're, 'in the air' ALL bullets are dangerous and potentially lethal. Experience has taught me that as long as you obey Cooper's Fourth Rule of Gun Safety, and line up your bullet path angles correctly then your shots are going to be as safe as you're capable of making them.
Super-duper, whiz-bang ammo really isn't needed. Neither are so-called, 'low penetration' jacketed hollow points. A safe accurate shot is a safe accurate shot. If your background isn't clear then don't take the shot - That's what bullet flight path angles are all about. (I've stopped a lot of wild game with FMJ and JSP bullets. Almost none with JHP ammo, though. That should tell you something.)
If I were going out to buy more 45 ACP ammo than I'm presently holding in inventory, I'd try to find more Fiocchi 45 ACP FMJ ammo. Barring that, I'd get Hornady, 'Critical Defense' FTX cartridges. Buy the way, forget about, 'outrunning' a bullet. It's not how fast it goes, or how hard it hits. Numerous targets have taken multiple hits from large caliber pistol gunfire and still lived long enough to kill the person shooting at them.
Anytime you assess a pistol cartridge you've got to put all of the important factors together. Bullet: caliber, weight, nose design, cross-sectional density, center-of-gravity, muzzle energy, and muzzle velocity too. The last important component of every ultimately effective bullet is, 'shot placement'; and THAT is entirely up to the shooter. OK.
