When the dude at the counter found out we had suppressors he immediately demanded to see our paperwork. It wasn't a problem, we both had it, but my buddy was kind of azz whipped by it. The guy said "I need to see your paper work right now". Jeff said "you don't need to see it". He said "yes I do". So, Jeff showed him his paperwork while explaining that the only ones we're required to show paperwork to are ATF agents & Law Enforcement.
Who's right, Jeff or the Range employee?
Have you ever been asked to show your stamps?
If we didn't have them with us, then what?
Asked to leave? Turn us in?
Honestly, if you are shooting a Class III firearm and don't have a copy of your paperwork with you, I think that you are asking for a boatload of trouble one day. My opinion, nothing more.
As to your question, every time I have shot at H&H with Class III I have had to show my paperwork to them. Now, I just hand it to them before I ask for a lane.
The first time it happened, I asked them about it. Other than it being their range and their rules, I was told that it was for both the range's protection and mine.
If they have seen my paperwork and verified the serial numbers, they know my firearm is legit. And if anyone else asks them about "the guy on lane 15 with a machine gun", they explain that it is legal and they have verified it as such.
They also explained that if someone were to call the cops and report a machine gun being fired, they could and would intercede before the SWAT team showed up and pulled you off the lane.
I know that several times when I have been there, I have drawn a bit of a crowd in the observation areas (as well as on the lanes) and on more than one occasion, the front desk had to explain to a lookie loo that there was nothing illegal about what I was shooting.
Yeah, the guy at the front might have been a bit more "customer friendly" when requesting your paperwork. At the same time, you guys might have been more proactive in showing it before being asked. This might have been a case of you guys hearing something that wasn't meant, and the front desk guy seeing something he didn't really see.
I keep a laminated copy of my forms in the gun case with the gun during transport or in a notebook. I am more than happy to show copies of my forms, especially if it opens an opportunity to educate folks about Class III ownership.
