I've been to The Gun Store a bunch of times. They have a decent selection of handguns ( but they aren't in top-top shape, but acceptible ). It's not a bad place to go if you are contemplating purchasing a handgun and want to try out a wide variety to help decide on which type of gun you want, since most other places won't/can't let you shoot a whole bunch of guns before purchasing. I never asked about fully auotmatic weapons there, though. They must get an awful lot of "newbies", but seem to be fairly tollerant of them ( which definitely is not true of most gun shops ).
In LV, there is some pretty heavy advertising directed at japanese tourists; since there gun laws are soo strict over there it's apparently a pretty big attraction for them ( although the places aiming at that market segment appear to be priced significantly higher ).
