As is the case in most states.
Here in Colorado, all gun show sales are already required to be subject to background checks, so there is no "gun show loophole".
Notice that the language has changed now, though. It's no longer the "gun show loophole", it's the "background check loophole".
ALL private sales are in the cross-hairs.
Full registration being the goal (for starters).
Yeah, well, apparently not so in CentralCal. You try that in someplace like say, San Jose or Santa Clara, not only will the cops come over and harass you for Driver’s Licence, Registration, Proof Of Insurance (”You drove here, didn’t you? Show it. Came on the bus? Did anyone see you get on or off it to verify?”), other Photo ID, Firearms Dealer’s Certificate, and a Concealed Carry Permit to name just a few, if you give them any attitude then they threaten to arrest you “on suspicion of being a drug dealer”. Really.
