american shooter supply(former b&j), oakwood trading post on oakwood ave, guns inc are all $525 + tax on regular frame glocks. gen 3 or 4 doesnt matter with plenty in stock.
firefly on nyfirearms has a decent price if i remember, but availability was an issue. for some reason he couldnt get me a gen 4 when i requested it not that long ago. like cossey said, his gen 3 price isnt that bad.
FL/UT/AZ pistol permit class tomorrow :number1
