I only own two calibers in a semi-auto handgun. .22LR and .45 ACP. Well, and a .380 pocket gun, but I don't consider that a range pistol. I shoot it enough to stay current on it, but it's not one of my fun calibers.
While I admit and appreciate that lots of folks like the other calibers, I've never seen the utility. But then, I'm a curmudgeonly sort.
