Sounds like BS to me. All kinds of hammer guns don't have a safety. A rebounding hammer is a safety. Most CO's wouldn't know one end of a gun from the other.Actually there is or so the CO's I worked with told me? If a CO determines in his estimation that your firearm is in unsafe working condition they can seize the firearm and a few I worked with me told me a gun without a working safety falls in the category of a gun in disrepair.
