The name magna identifies the style of grip in which the wood comes up over the sideplate and frame, rising to the height of the frame knuckle right behind the trigger. Your gun might also have come with target stocks, in which the wood follows a semicircular upper curve from the frame knuckle down to the rear trigger guard junction with the frame.

The following guns are not K-22s, but they show the types of stocks I mentioned.





The K-22 is a K-frame gun (or midsize), so you are looking for K-frame magnas or target stocks of the proper era. N-frame stocks are too large and J-frame stocks are too small. Old stocks can be found on Ebay, Gunbroker, and in the classified section of this forum.
