A question for you folks.... did all the Mark II (Target Models) have screw retainers for the barrel catch or did some have pins? I have seen in Gordon's book one that appears to have a pin but no mention of it in the text. Similar no mention of a pin in John's Encyclopedia. However I have a Stoeger Mark II that appears to have a pin.... but it's just as feasible that the screw in both examples may have been sheared off...

All the best,
Jimmie
