Yeah you can get a shot gun from any where between 150 and 500+. Rifles more or less the same. That's funny how you can buy a 12 gauge at the age of 18 and not a hand gun. Our CA govt. says that when we turn 18 we are allowed to carry a fire arm that can take down a water buffalo, but we're not allowed to carry a pistol. I know it's because of the concealable factor. It's harder to hide a shot gun than a pistol. But if your intent is to kill someone then a shot gun will do just fine no matter how old you are. Ya know, get all stealthy with that shot gun, put a supressor on the end of that bitch like the guy from, "No Country For Old Men." 'What shot gun? I didn't hear a shot gun.'
Yeeeaaaahhh... So if our lovely state is ever over runned by water buffalo, then thank god every one 18-20 has a shot gun because, damn , that could have been a close one.
