I really enjoy using the range, and I'm grateful that we have it available to us. I'm also grateful to the ROs and RSOs that help provide a safe environment for all of us.
That being said, I don't believe they are volunteers... and since we're (indirectly) paying for them, we have the right to expect a certain minimum level of service; to my mind, that includes a courteous attitude. You CAN be courteous and firm at the same time. I've never had a negative interaction with any of the RSOs, and have been courteously corrected on a couple of occasions when they've been concerned about minor details of what I was doing. No problem with that. On the other hand, I have seen RSOs deal with shooters from a perspective of "you're an idiot, and I've got power, so I'm going to make you feel little and stupid." Not OK.
Regarding leaving a loaded magazine on the shooting bench when going downrange... I agree 100% that it is MORE safe to not have loaded magazines on the bench while folks are downrange. I think the risk of something bad happening when there's a loaded magazine on the bench is very small, but it's even smaller when there no loaded mags on the bench. That doesn't make it a range rule. If you want it to be a rule, post it on the signs with the rules, and if it applies to the handgun side, it should equally apply to the rifle side (you seriously think it's more difficult to pop a loaded mag into an AR than into a Glock?). "Range commands," to me, means "approach the bench, handle firearms, and commence firing," "complete your firing," and "cease fire." So that means, IN MY OPINION, that "don't leave a loaded mag on the bench during a cease fire" is neither a range rule nor a range command; it's an RSO/RO enforcing a personal preference... which is OK, but if it's my first time to the range, don't expect me to know about it and don't treat me like an idiot if I inadvertently violate that non-rule.
Summary: NOBODY benefits when ANYBODY starts flipping attitude. Let's treat each other with respect and have a safe (1st priority), fun (2nd priority) time.
