Many of the old time Sicilians I grew up around loved those little .22s. It took me a few years to figure out what they were really talking about!

what size bullet is best for self defense a 9mm or .45 acp?

The correct answer is: YES.

[Azrael2004]

The correct answer is the cartridge and firearm combination you are most comfortable carrying, and that you can consistently deliver combat accurate hits with to stop a deadly threat.
If for you that's a Beretta 22 LR that's the best, If it's a S&W 500 Magnum, then that's the best.

No one wins with missed shots using a bigger bullet. A person intending to do you harm won't stop when he realizes you just missed him with a 45ACP, but a pair of 9mm rounds to center mass will certainly get his attention.
