I'm not in favor of mixing alcohol and guns.
If the guns must be secured in the vehicle before being served...I'd think thieves would target the parking lot.
OK,I'll try to play devil's advocate for balance.
In my state (Colorado) my understanding (I'm not a lawyer) is you can be in a bar ,concealed carry, and have a drink in front of you. Supposedly, you might be legal having a beer with a green chili burrito plate. The legal limit for being armed is the same as the legal limit for being impaired to drive. I think thats a .04 BAC. Its also my understanding Law Enforcement has the discretion to take your firearm and permit regardless if BAC if you have been drinking.
It can certainly be argued that a drunk driving a Suburban is as dangerous as a drunk with a gun. Neither are good.
Not everyone who sips a beer is drunk. If you serve alcohol to the public,somebody will get drunk.
If it were my Indoor Range I would not do it. Insurance,potential lawsuits, anti-gun press, public nuisance petitions, and the potential of gun shot wounds...
I can't see a way to make it a good idea.
Maybe,if an entrepeneur owned a corner lot/mini strip mall, there could be multiple businesses. One Suite,or bay,could be an indoor range. On the same lot, there could be a gas station / convenience store/liquor store.
