My M-27 that I bought new in 1989 has a broken yoke. The tube that the cylinder rides in broke off from the frame on the yoke. I have fired 15,000 rounds through it, mostly .38 Specials. It sports a 8 3/8" barrel. Has anyone else had this happen? I have larger caliber S & W N frame revolvers; kind of surprising that the M-27 woudl be the one that has a broken yoke.
