1981, the first year of L frame production. In fact, IIRC 586 serial numbers started at AAB or AAC, so you have one of the first ones made.Serial # AAC1XXX, 586 no dash#
FWIW S&W recalled all no-dash and some -1 L frames because some firing pin bushing holes were oversized, which can cause primers to backflow into the hole and lock up the gun. Older repaired guns were stamped with a big "M" inside the yoke cut, although AFAIK S&W has stopped "M"-stamping recently repaired guns. (Some guns were also "M"-stamped at the factory.) If your 586 hasn't been "M"-stamped, you might want to send it back in, but if you've been shooting it for years without problems, it might not need the recall repair because not all L frames were affected.
