Leon is a jerk in many ways, and always has been.
He violates his merchant agreement with Visa/MC/Amex by charging extra on a gun the second he finds out you're not handing him cash.
His range fees are ridiculous.
He and his staff care more about sucking up to Metro to try selling MP5's than they do about regular customers.
He does everything short of saying "we will not do an FFL transfer on a gun you don't buy here" by charging 10% of the value of the firearm + additional fees if you have a gun mailed to his shop.
He and his staff have always been anti-OC. This isn't really any kind of recent change.
Go anywhere else in the valley for better prices and service. The Gun Store, American Shooters, Spurlock's, etc.
P.S. On the original topic, one of the main instructors at The Gun Store for their CCW course is a Clark County Sheriff who is rabidly anti-OC and goes out of his way to rail against it and threaten people with being "thrown on the 120 degree pavement" if "caught" OCing by Metro.
He also erroneously teaches that "no guns" signs carrying the force of law in Nevada (which they do not). Finally, his attitude reminds me a lot of the DEA agent in Florida with the "I'm the only one in this room professional enough to..." type garbage.
They're cheap, and you can fulfill the state requirement, but don't expect to be dazzled with all the useful information.
