I haven't read all of the post so if this has been mentioned already. After reading the OP first thing that came to mind since the do classes there perhaps that's what the sign asking for unloaded guns, and slides locked back was for people coming in for the classes. I know the gun shop where I took my class we weren't allowed to bring guns into the classroom. We left them at the front counter with shop employee who also assisted the instructor during the shooting part of the class.
