Wow! If only the Russians could have adopted such an adjustable sight for their commercial models.No, the Chinese adjustable rear sight is almost the same as the fixed sight. It has a very small rear blade that is adjustable only for windage and two tiny screws to do so. In photos they are at times hard to tell apart. In a profile photo, look for the tiny screw under the blade. The Makarov in my photos has the fixed rear sight.
