Just about every website for manufacturers that make both revolvers and autoloaders categorize them as "revolver" and "pistol".
See the above images.
Because people misuse words does not make them correct terminology. For instance, I might invite you to my home, residence, domicile, house, apartment, condo or townhome. I will not invite you to my "crib". :barf:
Technically, revolvers are no longer pistols. Those who say they are are using a century old definition. We don't use century old definitions elsewhere, why would we use them here?
Where's the Bull---- flag?
You can come up with 'centuries old definitions' for many things if you think about it. "Toilet" isn't exactly a new word. Nor is Fork or knife. Last I looked, balloon was at least a century old.
Because "common use" today segregates revolver from "pistol" does not mean the usage is strictly correct. How many people say they need to buy a "box of shells" for their 9mm? That's incorrect too. So is saying a "box of bullets" unless you intend to use them with your reloading gear. A box of ammunition or cartridges is correct. We tend to be sloppy with our language at times and we should be mindful of how that often confuses things over time.
