Wow. That escalated quickly. Just for clarification, this is a factory dao. No bobbed hammer. It has no single action notch. Even if you pull it back manually. My understanding is these pistols were built specifically for law enforcement, although I have no proof. It was bought through a company called J&g sales & I know they sold a **** ton of them. It's a beautiful gun. All stainless. 4in barrel in 38 special. I've already found a hammer for it through numrich for 60 bucks. Just gonna change it & see what happens.
