You dont know i have the Cowboy perk but im not sure and i dont see why it wouldnt be cuase it is a revolver
It
should apply....as revolvers in game that are modeled on current day revolvers (.44 Magnum, Mysterious Magnum, Hunting Revolver, Sequoia) get it, not to mention the futuristic That Gun....but it doesn't. The Police Pistol is modeled on the Colt Police Positive Special, a popular police sidearm designed in the 1920s. I suspect they didn't apply the Cowboy perk to it as they felt it would be too effective on the Ghost people. I wish they would fix that, as well as fix how it has no rear sight notch when you're using iron sights. As a weapon, I've found it to be quite effective against people, feral ghouls and smaller critters, especially using FHPs.
