It's in Mesquite, NV, not Las Vegas. I've been there. Mesquite happens to be almost exactly the midpoint between Salt Lake City UT (where I live) and Valencia CA (where my Dad lived until 2 years ago). So we'd meet up in Mesquite twice a year for many years.
As Mesquite is in Nevada, the primary employers in town are four big casinos. Gambling invites people who lose at gambling and find themselves financially inconvenienced. G&G is basically a pawn shop serving this clientele, with a full range of steel string and electric guitars from $79 to $7900. They had one CG there, a Yamaha for $100 or so. I've zero interest in weaponry, but just from looking at the wares offered they go from purse-size pistols to handguns to hunting rifles to anti-tank defense systems. They also have some jewelry, watches, and so forth, but their main stock in trade are the guns and guitars.
