I wouldn't bother for a uniform copper. Its also not a big stress for you right now, however if someone is going to be alone with me in my home when I unlock the cabinets and hand him multiple rifles, shotguns etc. to check, I think it is appropriate to ensure they are who they say they are. It feels the responsible thing to do. Given you are applying not renewing, I guess its less of a worry at this point.
I also make them tea and biscuits and we have a good chat about stuff - it certainly doesn't pay to be rude - but polite and security conscious is, I think, appropriate.
