I reload for my G20, and it's one of my favorite handguns. However, that opinion of mine really isn't germane to the paucity of activity on the 10mm forums! Obviously, as far as 10mm interest goes, I'm NOT e pluribus unum!!!!!
Yes, it's true that you can get a Glock 21 to fire 10mm with a conversion barrel; however, it's NOT TRUE that such a conversion offers reliable extraction. And yes, I know from experience!
