As a resident of Missouri, I am no expert on Kansas law. Please do not take anything I say to be legal advice.
Now that I have disclaimed any perameters as to my legal authority, please allow me to exercise my common sense authority. Whether this has anything to do with law is irrellevant. It is merely my opinion and should be taken that way.
What is the point of carrying an unloaded firearm?
Without bullets, it is unable to be used for it's intended purpose: To propell a chunk of metal at a high velocity. Without this chunk of metal inside your firearm, it is physically unable to be puked out the end of the barrel.
Without bullets, your gun is very similar to a snow globe, Christmas tree ornament, Playboy centerfold, diamond ring, or hunk of tasty cheese: Very nice to look at, but unable to propell a chunk of metal at a high velocity.
Without bullets, your gun does not protect your life. It merely appears to be able to do so. Much more dangerous than even being unarmed as you will be more of a target, but a target with the same capability as an unarmed person.....roughly the same as a person carrying a hunk of tasty cheese: Unable to shoot back.
Therefore I'm merely speculating that Kansas law would encompass being able to carry a loaded gun, as an unloaded gun has no purpose whatsoever other than to make a person more likely to be shot in a dangerous situation.
Take no legal advice from my response, but please take some common sense advice from it. If Kansas law does turn out to prohibit openly carrying a loaded gun, you'd be better served by obtaining a permit and carrying concealed as the gun would then be able to be loaded and actually useful in saving your life.
