My brother-in-law and I want to go to a large gun convention. I have read that they usually have good deals on 50 rd PS90 mags and since I still only have one, I need to get more. I know Shot show is the place to be, but it is only for FFL people according to their website, so normies like us can't get in. The local ones here in WA are small, about 60 tables that I have seen on the internet, plus I don't know which ones are actually real good. Anyone know of any comparable shows that are open to the public? I don't mind traveling.
