    I've seen it on a number of modern revolvers, though not Ruger. My old S&W 686 doesn't have it, but a newer model I have does.

    The raised area you refer to is the cylinder stop. It keeps the cylinder from moving rearward when it is out of the frame. ( as in during ejection of the empty brass)

    ^^^^^^^^^

    What he said. S&W cylinders are retained by the crane and frame. When the crane is removed from the gun, they slide right off.

    Correct, but technically, it's called the frame lug. The cylinder stop is the doohickie that keeps the cylinder from rotating.

    Older Smiths use a smaller tab that's pressed into the frame. AFAIK, the newer lugs are part of the frame, and non-replaceable. You don't want to damage it. :cuss:

    The change was made in 1997 I believe. The prior method of pressing a cylindrical lug into the frame and then machining it to blend into the frame window was stopped, and cnc'ing this much larger piece out of the frame was instituted.

    Thanks, all, and especially Oro. I'm familiar with the tabs, but didn't know why Smith changed the entire side of the gun. I wonder if it was function or fashion?

    It was done to cut costs. Not to improve the revolver. Just like all the other "innovations". :rolleyes: ;)

    Cost while retaining function.

    It is easier and more accurate to machine it as part of the frame than to drill a hole, press in a separate piece and than hand fit that piece to the cylinder

    Spot-on.

    One thing we seem to sometimes not think about.......

    We all like to look at older guns that were put together with lots of intricately machined parts, and we see this as quality. But........

    Modern technology allows many things to be done in ways that are not only simpler and more cost effective, but also stronger and more precise.

    Forging processes today can turn out a blank that very closely resembles the finished product, versus the less-precise methods of yesteryear that required tremendous amounts of milling on the rough-forged piece.
