Heck, I live in NY and cannot think of a gun shop that makes people disarm before they enter. First of all, in nY I guess that would be illegal in some places, for instance NYC. If you have a permit you have a permit to carry not to leave it in your car. Certainly it would at least be a major liability. Imagine a dirt bad finding out that anyone going into a gun store must be unarmed. A few things could happen. If the bad guy wants to rob the store, he has only employees to worry about for the most part. Second, if he is without much courage as are most, then maybe he will hit the easier target, all the cars of people he saw go into the gun shop within the last five minutes. Heck, if he was watching he even knows where you stashed your gun. Now if he gets your gun out of your car who is at fault? First of all, you are for leaving it there but, some of the onus likely will fall on the gun shop owner (almost guaranteed in civil court).That is a plainly ridiculous requirement.
As far as what someone said about unloading at the range, I never unload my carry firearm at the range, only those that are meant to be fired while there. My carry piece stays on my hip (unless I am shooting it too but even then it does not get unloaded). Then again, no one is telling you not to enter with a firearm, and no one prevents you from ultimately loading it and firing it. So the analogy of the range to the prohibitive gun shop does not hold water.
I would have walked away from that gun shop, gone to another, bought all of my supplies there, gone to a Kinkos, made a photocopy of my receipt, then brought the photocopy back to the people in the 'no guns' gun store so they could see the business they lost by their rule which they obnoxiously posted next to a poster of the enemies of our rights. That sign next to the other was no funny coincidence. I find many gun store owners to be in it only for the buck and, not at all to help support our right to have firearms. I recently stopped using a guy who required me to show my creds to buy a certain caliber of pistol ammo. I have been shopping at his store for years, he knows I am a fed, yet he demands to see my creds when I buy 32 Auto because, according to him, it is a bad guy round. I can buy a case of 9mm from him without showing any ID, but noit 32 auto.
Not much by the way of customer relations. I found a friendlier source, that is also less expensive. Guess where I shop now. Think about that gun shop owner, he thinks and espouses that 32 auto is a bad guy round! What does that do to boost the craziness of the anti-gun nuts? What does that say about his knowledge or lack of knowledge aboiut bad guys and guns and ammo? What does that say about what he really thinks of his customers? I shop elsewhere now and, he can take the 32 Auto and sit on it.
The thing that gets me is that many of you here seem to put up with, or even support, stuff like this from gun shop owners. Sure htey can run their shops as they please, but if it would not please most of their customer base (and the customers let them know this) then you would see how quickly that rule would change. People have to let these shop owners know, in polite but certain terms that such is not acceptable. If they hear it enough, and if they see a dropoff in customers who return, they will change that kind of a rule.
All the best,
