i was bored and was looking at gunbrokers website.. i searched for glocks and ran into a glock 18 automatic handgun (drool) (drool) for 2000. i live in tucson,az and there are no class 3 dealers..say i travel to phoenix... and tell them i want it...what should i expect? can i go in there fill out paperwork pay the permit and then order it? or is it alot harder than that? is the permit a one time thing? that would be completely extraordinary to add to my collection!
