The following quotes are borrowed from iCarryUtah.com:
Keep in mind that if a sheeple gets scared, they WILL call 911. They won't say that they saw a man with a gun in a holster. They will say they saw a man with a gun. After the "telephone game", that will most likely be interpreted by the responding police as a "man waving a gun around and scaring people".Open Carry IS Legal in Utah - however, there is a big difference between the abilities of CFP holders and non-CFP holders. There is also the matter of wisdom in the matter. IF YOU HAVE A CONCEALED FIREARM PERMIT - you can also open carry a fully loaded firearm. You give up the advantage of surprise, and can attract unwanted attention.
There is also the matter of LE response. Unfortunately, our myriad and copious number of laws has created the situation that no LEO knows ALL of the laws they are charged to enforce. This includes the laws relating to firearms. While most SHOULD show up, see someone acting peaceably with a holstered firearm, and walk away - there are some that will react as if they are observing a felony in progress. Do you really want to go there? While you should not have to worry about this, the sad reality is that you do. The Utah State Constitution is preemptive - (Utah) open carry is legal throughout the state, and no subordinate municipality can detain you simply for carrying a holstered sidearm in plain sight.
Be aware that Utah has a rather unusual definition of "unloaded" (which is the only way you can OC in Utah without a CFP).Also be aware that your Oregon CFP/CCW (assuming that you have one) is not valid in Nevada or Colorado. Enjoy your trip!Utah unloaded" means the gun will be in such a condition that it will require two separate mechanical actions to cause the gun to fire. In Utah, a round in "firing position" = loaded. If semi-auto, no loaded round in chamber but magazine may be loaded. (rack slide = one action plus pull trigger = 2 actions). A cocked and locked 1911 is considered loaded, and therefore illegal without a CFP. If a revolver, the chamber under the hammer AND the next one in rotation must be empty. This gets you around the loaded firearm definition in Utah (if the chamber under the hammer has a round, then TECHNICALLY there is a loaded round in firing position even though PHYSICALLY and FUNCTIONALLY that round won't fire as the trigger will first rotate the cylinder). Two pulls of trigger = two actions. This leaves you two down on a revolver, and at a further disadvantage. On this one, don't expect the average patrol officer to understand the direction of rotation on the cylinder. Many of them have never handled a revolver before. Just be prepared, and again, ask yourself if you really want to go there.
