I went to one yesterday morning in Greensburg, PA.
New gun prices were high, military surplus were too.
Things like parts, accessories, magazines, holsters, and reloading gear could be had at decent prices. Alot of stuff at around the best price you'd find on the net but by buying there you dont have to pay shipping so it made it a good deal.
Didnt buy anything, almost bought a Spikes stripped lower for $99 which is $10 over what spikes sells them for, but I wouldnt have to deal with shipping cost to a FFL and fees. Might go back tomorow and get one.
Oh I saw a very cool thing. The local county's Sheriff's dept set up a stand where you could fill out your application, they'd do backround check, take your picture AND issue you a PA License to Carry Firearms (CCW permit) on the spot!!
Very nice, friendly sheriff and deputies, I picked up a free guide to PA gun laws from them.
PA residents had to live in Westmoreland county to apply for permit and I think they were even doing out of state residents as well. If I lived in that county I'd vote for that sheriff every election!!! Very cool!!
