That should be any and all info that you really need as for the CCW ordeal. As for legal policy on carrying it should be in there as well, but you can carry weapons in your car but you cannot have them loaded at anytime they are in the vehicle. Gun rack is preferred to eliminate any issues during a simple traffic stop. If you dont have you guns in plain sight and/or fail the officer of your weapons from the very beginning it can lead to issues you dont want to deal with, so if you dont have a rack the best offer you can do is "place both hands on the steering wheel before the officer gets to your car, when he gets there let him know right off the bat that you have weapons in the car"
This is just simply for the posession of the firearms which you DO NOT need a CCW for.
As for shooting places in northern colorado its very minimal due to needing a membership and everyone is tight to let theirs go due to the recent election decisions. y our best bet if you know anyone that owns land you can shoot on that land just as easy as shooting at a range.
My mom happens to file and approve all of the CCW paperwork for the county sheriff so if you have any questions regarding this topic that the website does not inform you or that you have questions about. Lemme know and i can give you my mothers ext. so that you can speak with her.. She will prolly be more reasonable then you calling Larimier sheriff or CBI or anyone around denver area.
Anyways lemme know if you need anything, and i hope that info is helpful for you.
