    As a machinist, my best guess would be by looking for any hint of a seam down the center of the part and/or a hint of a nib, or removal thereof, somewhere on said part.

    Honestly though, if the manufacturer did a proper job, you will probably never be able to tell.

    Dull appearance and a lack of case colors and is hollowed out on the back side of the bow of the trigger. Began to show up in the late 1990s on some models. May be avoided by purchasing good examples of revolvers of earlier manufacture.

    The revolver in my avatar photo dates from 1926, is a Military & Police .38 Special and doesn't have any MIM parts.

    Methinks the 686 made its debut around 1980, so that should be the no-dash model vintage. I'm quite sure that predates the appearance of MIM parts at S&W.

    Also, I'm almost positive all the S&W revolvers with MIM hammers do NOT have hammer mounted firing pins like the older forged hammers did. MIM isn't strong enough for that I'm told.

    Good point.

    I've heard that the MIM wasn't suited to hammer mounted firing pins as well. MY 1998 vintage Model 642-1 has an MIM trigger but a case hardened hammer with a hammer-mounted firing pin. Came that way. With the side plate removed the revolver's hammer may be manipulated to cock as it still has a perfectly serviceable singled-action sear. Weird.

    Didnt S&W go with MIM parts, around 1998-1999, Or somewhere close to that date?

    If it has a lock above the cylinder release then you got MIM. Also if you look at the trigger and hammer many times the MIM parts have a slight hint of a line straight down the middle.
