    Strange round black marks found on most S&W Revolvers?

    At first I thought these were stains and tried to polish one out. Then discovered they were put there on purpose, and were on both sides of the frame. Also on other guns shown.

    What are they, and what purpose do they serve?? One person told me he thought they were there to represent screw placement in earlier version guns?? Personal preference, I would just as soon not have them on there. Can anybody enlighten me on this??

    I've never seen anything like it on any S&W I've owned or shot

    They aren't pins running through the frame?

    They are pins...Titanium, I believe. I just read about that a couple of weeks ago. I might remember the metal incorrectly, but they are pins.

    They use them in the lightweight "Airlite" Scandium frame guns.

    Those are the studs that the trigger, hammer, and cylinder stop ride on. All S&W revolvers have them. They are pressed into the frame during manufacture, then "dressed off" to match the frame contours. The reason you can see yours is due to the dissimilar metals used. That is either an alloy or Scandium frame; the studs are tool steel. Most chrome-moly or stainless guns use similar metal in these studs, so they don't show up as prominently. If you find them aesthetically objectionable, you're out of luck.

    I'm glad no one beat you up too bad; it was a reasonable question. At least you didn't ask about the "frame crack" (sideplate seam)...
