I'd say make your way out to a game and feel both. You're bound to find someone with a Glock 19 and a 17 or 18 (the 18 is the full auto version of the 17). The grip on the 19 is a bit shorter and smaller I think. It's personal preference more than anything. I've held both and didn't find a huge difference.
