I am planning a road trip to Denver soon and plan on CCW'ing with my AZ permit.  Is there anything I need to know like mag limits or special laws in Denver itself?

I am going to the University Hills / Glendale area on I-25 and S. Colorado Blvd. Also I will probably go up towards Moab and then take I-70 east as I imagine that snaking up from Durango might be really questionable roads this time of year.

Thanks for any help

Even though Denver proper is a liberal dump, there's no real nasty restrictions on CCW there.  The magazine law really only affects purchasing new mags, not ones you already own.

I would suggest you review CO's carry laws at the following link.

Like the fly said. However I'll add that Denver city and the surrounding metro cities are particular about open carry so try to be sure it doesn't peakaboo. You won't be arrested but I've known 2 people who were detained for a minor slip

The major change from AZ you will need to be aware of are no firearm signs dont mean anything legally. They need metal detectors and security screening everyone at the enterance.
