Bingo! Nickel magazine has the spring guide rising from the base. I didn't catch that last night. Both the base and the pin are very snug, so much so that I would think it was factory and had never been disassembled if you hadn't told me otherwise. There is no marring on the pin, and the base is immobile. There is a slight amount of up-down wobble on the blued magazine. I'd say about .5mm. When I press on it, it gives off a slight "click" which is more noticable than visable movement.
Anyway, thanks for the clarifications. I don't think I am going to bother disassembling the nickel mag to right it. If it feels as tight as it does, whose to say it wasn't Unterscharfuhrer Johann Schmidt-Schultz himself that didn't do the mod one boring day during the Sitzkrieg of '39-'40? Or maybe it was Brad McBackbacon back in the '50's when he bought this thing for $25 from some vet down the block who needed the money to buy that new Chevy? All I know is it's that way now. The mag is tight and seems to function well, so I'm not messing with it.
Thanks again for the info.
