My M-27 yoke broke ....the tube that the cylinder slips into broke off at the junction where it meets with the other part of the yoke. I do not shoot many heavy loads. Most .357 Mag loads are at under 1,100 FPS and with 158 SWC cast bullets. Has anyone else had this issue? I will be contacted S & W and hopefully they will repair it. My Ruger SS BHK .357 has shot many more rounds with only a few transfer bars breaking.
