This is a great writeup on defensive ammunition:

To quote for your caliber:

The .45 ACP is a recognized manstopper, and there are many
excellent loads in this caliber. Some of the best:
- Federal 230 grain Hydrashok JHP (P45HS1): a great load, and my #1
choice. It gives the most stopping power in this potent caliber.
- Federal 185 grain JHP (45C) another top-notch load from Federal. I
would choose this round for a compact, short-barrelled .45 like the Colt
Officer's ACP or the S&W 4516. It has lighter recoil than the Hydrashok
or CCI 200 JHP, and its higher velocity makes it more likely to expand
out of a short 3.5" barrel.
- Cor-Bon 185 grain Sierra JHP
- CCI Lawman 200 gr. JHP (3965). a.k.a. the "Inspector" or "Flying Ashtray."
- CCI Blazer 200 gr. JHP (3568). The "Flying Ashtray" in an economical
aluminum case.
