5 1/2 stainless ady sight bisley bought it about 2 weeks ago and brought it right to my gunsmith for an action job and a belt mountain pin. Just got it back last night now its to the range to give her a try. Now I have the .44 to keep the .45 company. As a side not I just got my .475 back from SK grips he fit my stag grips to the frame. He does a great job I also have a set of french walnut stocks on my .500 he made and they are beautiful!!!
