I'm curious if anyone has ever had any problems using a suppressor at a public range ... in a state where they're legal of course. Have you ever been questioned by LE, range officers, other shooters, etc? Suppressors aren't that common so I could see a trip to a public range turning into a circus. I'm not sure if the majority of LE officers know the law (federal and state) regarding suppressors so I wouldn't expect them to immediately demand to see a tax stamp. I would imagine that they'd have some questions though, assuming they're at the range.
