Which Glock should I get?

I am 14 almost 15, and I want a Glock. My parents will allow it and yes i know alot about guns. I own four already and i don't want any trash telling me that i'm too young and/or don't know anything about guns. I am friends with a guy who owns a hunting show. He is partnered with Glock and I shot his 10mm and fell in love with it. However, I have a budget. I want a Glock and no other brand of gun. My budget is $400 but that can be a little flexible by maybe $30. I know that's alot to ask of a Glock since the name brand costs alot. I would like a Glock model that would be able to fit the hand of a 15 year old that is 5'8'' and around 125 pounds, so nothing really big. I do kind of like the Glock 19 because of its smallER size. I like 9mm but I want to hunt whitetail deer with this gun, and from what I heard, a 9mm would not be too efficient for that. I also do not want a caliber of bullet that is hard to find and/or expensive. My uses of this gun would be for deer hunting, hog hunting, and target practice, and home defense. I need some help, so your suggestions would be appreciated. THANKS as always.
