I'm shopping for insurance at the moment, and considering my options. I've always increased the firearm coverage on my renters/homeowners policy through my primary insurer. While they've never asked me for details or serial numbers, the company I switch to might request them, and I don't like the idea of giving that information out. I've heard there are multiple offerings from the NRA and others, which don't request a list. How do you insure your firearms?
