RaginRog,
No need to remove the grips. The serial # is AFP2279 and dates your revolver to 1984.
686 (no dash) started production 1980.
686-1 was introduced 1986.
Do not hold me to the following but the recall for the 586's and 686's was the mid 1980's and those that were "fixed" received a M stamped on the frame opposite the yoke either above or below the serial number as best I remember. Supposedly, back in the day, Federal brand .357 magnums had soft primers and upon firing they would deform rearwards binding up against the firing pin bushing area. Rumor has it that many S&W 586 and 686 no dash revolvers without modifications have fired plenty of .357 magnum loads without problems. One of the guys I shoot with has had no problems with his 586 no dash shooting .357 magnum loads.
