I, too, prefer the unfired, NIB(new in box) firearms but in all honesty, I highly doubt most FFL holders or gun shops have/sell guns that way.
In most cases, the sales staff or counter shop clerk says; "We only sell what we display." or "That's our last one in stock."(even when they may have 8/9 in the back storage area).
I get that gun shops & staff want to sell guns and make $. It's just that some shops or FFL holders do it better than others.
If a gun shop goes under, Im 100% sure there were some issues that could have been corrected or avoided.
Maybe some savvy TFLer or gun industry expert,
The Gun Whisper ???, could do a new "unscripted" series like Spike's
Bar Rescue or Fox/BBC's
Kitchen Nightmares & help fix up some of these gun shops/ranges.
