Great Service, gun laws suck

OCG is great. I've ordered 2 320's from them previously and their processing and shipping is fast. The 320 series is a great series of pistols. I can't really tell you much about this current pistol. Although it was processed and shipped quickly, my FFL dealer is going to have to sit on it for a couple weeks until I get my new "federally compliant" ID card. Despite the fact I have LEO credentials and my old Drivers License worked well on the 4473 for years, apparently, the Feds aren't quite sure I'm a US citizen and eligible to pick up my new pistol. Thanks for the professional courtesy BATFE, and thank you California for completely debasing the identity of your citizens.
