www.ar15.com/forums/topic.html?b=8&f=9&t=171009 I (and Ed and SP10) have been to the Rochester Gander Mountain. It had a good selection of huntin' long guns, but no black rifles. The selection of handguns was okay from what I can remember:
Glocks, but no mini Glocks on display, a Glock 17 was $ 400 (?)
Kel-tecs: I remember they had a 9mm Kel-tec that was $ 300
Smith and Wesson and Ruger Revolvers, some Berettas and some 1911s, I didn't get a good look at the 1911s though because there were a bunch of guys standing around there.
There is also a Galyans in both Rochester and Buffalo that are similar. The last I knew the Rochester Galyans had reversed their "no fun guns" rule and were stocking Glocks and some other semis, though I can't remember what.
Gander Mountain also had a pretty good selection of used long guns.
A couple of used pistols, I remember a Para-ordinance 14
