Some of the earlier Ruger Mark II’s (bull barrel) had the lug w/ the two knurled grips on the sides that was RIVETED on. I saw a failure of one with facial impact & blood resulting. Funny, the Walther TPH was one of the best .22lr pistols made. But it was expensive so it wasn’t that popular, and its very hard & expensive to find a magazine for one!
