i just watched a video on you tube and the guys lcr did not have the upper screw to hold it together, also the cylinder screw stuck out past the frame and not flush like others i have seen. do ya'll know when ruger changed them?, my 9mm was made in december 2015 and has the upper screw and my cylinder screw is flush. his was the snub not the 3 inch and his was the 22lr model. thanks
