According to the Open Carry map/Utah info:
Utah allows unlicensed open carry of a firearm that is at least 2 actions from firing. For example, a semi-auto may have a full mag but the chamber must be empty. Permit holder may open carry as well, but their firearms may be fully loaded.
So, if this is correct, you could carry your Glock openly, magazine loadedbut with an empty chamber. Unless you have a CCW. Then you could carry fully loaded.
IMHO, carrying with an empty chamber is better than not carrying at all. Just train a bit with drawing and jacking a round in.
