I was thinking about this the other day. I know there have been similar threads on here in the past, but it's been a while. What is the main characteristic that you like to see in a gun shop? Are you looking for the latest and greatest, just released MagPul or Daniel Defense products? Bulk ammo in stock, or a lack of variety, and absolute rock bottom prices?
Personally, I want good, friendly people behind the counter. Beyond that, I want to see a lot of used guns in stock. Not really because I think I can get a great deal on them, but because I like old guns. I can't go order a pre- '64 Winchester, or an Ithaca model 37, or a Savage 99, but I might find one used somewhere. The last few I've purchased haven't been because I was actively looking for whatever it was, but because I just stumbled across one at the right time.
