I could swear that, in the past, I've seen a Ruger DA revolver in 44 mag with a 4" barrel. It was like a non-super Redhawk or something. Or was I just hallucinating? I was just looking at the Ruger website, did a caliber search for all 44 magnum, and the only da revolvers in 44 are Super Redhawks with miles long barrels. (i.e. 7 to 9 inch barrels).
