I am in charge of an indoor range at a private club in Brooklyn, NYC, NY. We have about 200 members.
We are not a turnkey club. For some one to get a key, they must take a range safety course that is given twice a year. They must take this regardless of other qualifications that they may have. They also must come down to the club and shoot with me or shoot while I am on the range (more than once or twice). I make it a point to know, personally, how some one who wants a key handles a firearm.
So far.....it's been 20 years.....there have been no issues.
The club also has a rule that allows a member to bring a friend in to shoot - once.
After that, if the friend likes to shoot, they are free to join the club.
