I've been to three indoor ranges here, two frequently and the third only once. All three allow shooters to carry guns, but the guns have to stay holstered until you're on the firing line in your booth. None of the three ranges prohibit drawing in their rules, though I didn't do so at the range I visited only once. The two ranges I visit frequently have never had a problem with me drawing. One of them also has programmable turning targets, which is nice for reaction shooting and testing oneself when drawing.
