Well that's the title, but I think the discussion would be more appropriately "Why the .45 ACP offers the least advantage over all the other common self defense cartridges"
This is a subject that will sure enough start a Holy War, but It's interesting that 25 years ago this would be an absolutely preposterous discussion, as back then it was arguably "the best" of the lot. But things have changed and now, whether you agree with it or not, the discussion at least does have some merits.
I have always said I don't carry any gun because of the cartridge, but because of the gun. I know they all work, and I know they all work pretty much just as well. I just don't go in for, or find anything useful in worrying about one cartridge over another. Just like I don't find any meaningful difference in the .270 vs. .30-06 debate; waste of time.
Anyhow, enjoy the Holy War this thread is likely to kick off.
