Does anybody have a set screw that secures the rear sight on a Lightweight Single Six or know what size it is & where I might buy one ? I appreciate any help offered .
Thank you ,

Just pulled and measured mine, .113 x 40. So 4-40. Use a .050 Allen wrench. Oh yea, it's .135 long. The screw could be as long as .220. Hope this helps you out. Take care
