I've taken the Range Safety course and the Pistols 101 course at my local range. I have the membership, 1000 rounds of range ammo, and the desire to learn how to do this safely and well.

Is it worth mentioning that it's my first time to the Range Officer or should I just keep it to myself? All my mags are loaded because that just seems like good etiquette but I don't know. Do people stand there and load mags when they're empty?

Going alone, how long is a normal session? I'm only bring a Glock 19 and half a dozen mags, which I don't think will take me that long to go through. Is there some etiquette for how long you can (or should) take up a bay?

I just feel like there are so many unspoken things that I don't know. Or am I overthinking the entire thing?

edit so much excellent advice here. Thank you so much. I feel better about the whole thing.
