Armorer951,
Thank you for your knowledgeable answer. I have heard several different scenarios as to fitment. From cylinder bore too small, barrel and forcing cone too tight, and lockup. Good to know a 686 cylinder will fit. Nice Look. Did you have to do anything with the yoke and ejector rod and star ??? I would love to try this approach based on your hands on experience.. I will look for a cylinder in .22 mag. NICE JOB on that project, Congrats.!! I wish I had that kind of knowledge...Would S&W sell me a #686 cylinder with rod and star. ??? Any help and advice will be greatly appreciated.. Thanx again for your help... Best; George K.
