Hello all. N00bie here, been lurking for some time. Great site. Also been devouring all I can read about guns/shooting/safety/etc. Going to pick up my 21SF Gen3 (CA resident = no Gen4) after I get off work and intend to hit the shop's indoor range as soon as I take delivery. Other than safety rules and specific range rules (eg, this range has a no double-tap, no rapid fire rule), what range etiquette points should I bear in mind. Hypothetically, if you are a veteran shooter and you see me take the stall next to you, you're thinking: "I hope this rookie does/doesn't ________________." What are those thoughts? Any tips appreciated. I wouldn't want to unknowingly break any unspoken rules; piss anyone off; and I don't intend to break any safety rules.
