Is it legal to openly carry an air pistol?
I imagine laws for airguns are as varied as those for powder burners. Where I live, I am sure you could carry for instance a Crosman 1377 which is a fairly powerful air pistol but it looks like an air pistol.
I have Walther and Smith & Wesson air pistols which look just like firearms and I would not recommend any one carry them openly in crowded places.
Depends on where you live, but some of the cops now days will most likely shoot you and your dog any way.
