I went to Discount Firearms (about a 20min walk from the Venetian behind the Fashion Mall) just for the range, they didn't have much in the way of store stock on items we could bring through the boarder. I was looking for a real Blackhawk serpa holster for my Glock17, they mostly had Beretta M92 ones. But I did get to fondle a bunch of guns. They had this S&W pee shooter, I can't remember what model. Could easily fit into one's pants pocket while remaining concealed, a private security worker bought it up. Problem is that for some reason S&W didn't ship them with mags.
EDIT: Ah, found it.
They were apparently selling like hot cakes, DF got like 5 in and gone in less then 2 weeks.
