No range that I frequent, and I frequent quite a few, would permit you to enter the range with a loaded gun in a holster - any holster - if that's the gun you plan to shoot that day. If you're carrying a concealed handgun that you're not going to shoot they don't know, they don't ask, they don't care. All range guns have to come inside unloaded and in cases. The only range(s) that will permit loaded weapons in holsters, that I know about, anyway, are:
1. Any competition range, but even then you don't show up wearing your loaded weapon. You can walk around all you want, for instance, at a cowboy action range/match with your guns strapped on but they damned well better be unloaded.
2. Training ranges for any kind of self defense courses where you train to shoot from cover, at close quarters, or even long distance practice shooting at goblins, and EVEN THEN you don't show up with loaded guns in holsters.
Anyone know differently?
