Got a box of mags at an auction, and trying to figure out what Smith two of them for. Wish I could post pics, but can't right now, have to find another hosting site. A 45 ACP fits perfectly, both have a single row of witness holes, marked for 8 rounds. No caliber marked on either. Orange follower. Both have a small 2 stamped by the baseplate. The plastic baseplates have a tiny S&W in a groove. They are too big for a 1911. Any help appreciated. Thanks!
