I have plenty of experience in OC situations, Rich B. from the Connecticut forum can attest to that. I use to be a major OC advocate and pusher for OC training at PDs in Connecticut. So rant away with what you would do. I've been in some pretty sticky OC battles.
I'll try to avoid having the moderator smite me, but here goes...
Since you appear to be seasoned, I'd do the following:
1) File a records request for everything related to the stop
2) File a records request for the training material officers are given with regard to individuals openly carrying
Some other questions:
What reason was given for the stop?
Were you open carrying in or near a "sensitive place"?
Was "reasonable suspicion" voiced by the officers?
In Colorado are records public or not? In other words, are the authorities permitted to only release info/video to the party(s) involved?
After you got a better picture of things (and other readers here doing the same), and because of the fact that open carrying firearms other than sidearms outside of a group setting is likely to draw attention, concern, and likely police interaction - I'd openly carry a sidearm or two instead, with the serial # on my guns taped over, and without ID.
The question in the back of my mind is "Were you stopped because of where you were carrying, what you were carrying, because of your overall appearance (or some combination), or simply because
you were OCing?"
