Carryers permit

[XXzz-Trauma-zzXX]

Hey guys, I was just wondering who all here has a carriers permit. For those of you who dont know what it is, its basically a permit to carry a firearm in public but it has to be concealed. I want to get one for myself when i get old enough and be able to own a gun for protection. So I was wondering what are the laws and whatnot on guns? I know in the constitution it says we have a right to bear arms.(See Image below)

But what are the overall laws. I live in Tennessee so if anyone knows the laws for Tennessee I would love to know them.

I already plan on owning a Glock. I heard alot of good things about them.
