Talking to the police will result in you being given ambiguous information at best and totally wrong information at worst.
You're right that you can't OC in Denver city/county limits (they are one in the same) but elsewhere in the state you may OC freely except for federal buildings, school property and municipal property which is posted against OC. Colorado law doesn't care how you carry your handgun, chambered or not.
You MAY have an LEO encounter eventually but its by no mean guaranteed. Simply OCing a pistol is certainly not grounds for anything like disturbing the peace. In order for charges like that to stick you have to be actually doing something to try and scare people, like waving your gun around.
Carry a voice recorder when you OC and carry with confidence and you will likely not have any issues. Please keep in mind that the encounters you read about on the forum are the exception because "I carried my OC gun today and no one noticed/nothing happened" threads would get boring real quick.
Read, read, read and read the threads in this forum and please ask questions that you might stiill have unanswered but know that carrying a handgun around Colorado is a non-issue throughout 99.9% of the state.
