I recently acquired a .357 Magnum Model of 1950 (pre-27), SN S96XXX that I like quite a bit and shoots well except for one serious flaw - a bulged chamber (not really noticeable with the naked eye on the outside of the cylinder, but brass won't extract, and a straight edge held along the top of the chamber on the outside of the cylinder reveals the flaw.) I even had .38 SPL brass fail in the suspect chamber via longitudinal splitting, so there's no question in my mind it's a bulged chamber. So it's an N-frame 5-shooter for now. I'm looking for a replacement cylinder, or maybe a complete cylinder-extractor-yoke assembly. Question: would parts from a M27 or M28 possibly do the trick? Not so hard to find as a cylinder from a pre-27. If so, would a recessed cylinder be an easier install? I realize some fitting may be required to make this all work.

Thanks!

I think I would contact Smith & Wesson's repair shop to see if they have a cylinder and would fit it. I don't know if this was a defect or caused by a hot reload. You might want to try Numrich Arms for a parts search. Also, I have heard Pinnicle Guns or something close rechambers cylinders, so that might be another lead. Good luck.

Yes, they would. But if you get a 27-1 or later cylinder you will need the ejector rod also as they are left hand thread. Yours has a right hand thread. Don't get one for a 27-3 or 28-3 or later. Those do not have the recessed chambers and you will have excess slop when you open the gun. The cylinder stop on the frame will not be the right length.

great points, tennexplorer, the potential issues with the cylinder stop location being off by the thickness of the rim of the case for non-recessed cylinder and thread direction conflict had not occurred to me. Sounds like you may have done this before - Thanks.
