Make your own. LOL. I did this one from a S&W Brazilian and made a 45LC cylinder that is cut for 45ACP and full moons. No blast shields. I haven't fired it with a bare left arm, but it doesn't bother my arm with a heavy long sleeved shirt. What you do notice is a little bit of peppering to the face as your face is much closer to the cylinder than when normally holding a revolver at arms length. Yes I adjustable sights by milling the slot in the frame.
