I've found Staters are really good on this stuff for the most part. I had a similar 'encounter' where I was pulled over for speeding (yes, I was :?) and he asked if I had a firearm in the car. I told him yes and where it was. He then told me to please keep my hands visible and asked me how he knew to ask about it and I responded with "Because I have a CPL on record?..." and he said "No, because of the Open Carry pamphlets in your back seat." (Now, my CRX doesn't have a back seat, but that's where they were stashed, behind my seat)
But, he let me off with a warning to slow it down and never disarmed me.
Now, admittedly, we did disagree about Open Carry and ended up agreeing to disagree, but otherwise it was a good stop. I wasn't going to push the OC issue when I was only getting a warning for something I had done.
