Is this a truly complete list of handgun calibers? No, of course not.

There are no doubt more than a thousand variations if you factor in cartridge designs over the last quarter-century and counting.

If you want to get really deep into the caliber of calibers (see what we did there?), check out Frank Barnes’ phenomenally well-researched book, “Cartridges of the World.”

Nonetheless, this is a pretty good place to start.
