There's also TargetMaster, on 202, right near the PA/DE border. They allow drawing from holsters on their indoor range.
They do not allow drawing from a holster unless you are Law Enforcement and they know you. The lanes have a big metal shelf attached to them to prevent drawing. If you try and they see you you will be thrown out.
Years ago I used to shoot there, and even with this rule I found it to be e dangerous place due to untrained folks being there, and lack of range supervision.
TM has an annoying no-winchester white box policy, though. So if you go there, be sure to bring something else, or you'll have to pay their higher-than-average prices for ammo. (They also prohibit blazer)
