I can load them as light as a 9mm, or heavy as a hot 357.
And you get 15+1 in the gun. 10mm is the god of semi automatic pistol calibers.( anyone who digresses with a comment about Desert Eagle is a troll)
I could make a list of a bunch of guns i have, or "have", or wish I had. Why would one feel compelled to provide that infornation freely? Do you feel the need to show off? Is it some immature game of oneupsmanship?
I carry a G21 on duty, and a G23 off. The 10mm is a serious round, though. My good friend carries a G20, and it shoots good. I'd go with the G20, and throw in a Lone Wolf .40 barrel for practice so you can actually afford to shoot it.
