Hi V, actually, you should install the new original NOS I'm sending and hopefully it will work for all? The Mausers had a dedicated purpose built magazine made in Holland just to fit their Luger, and I'm sure Mauser designed their mag catch to be copasetic with the mag as well...??.. Anyway, the replacement will certainly tell you one way or the other, where the tolerances differ.. Best to you, til....lat'r.....GT...
