Saw some posts on the above, including reference to Numrich for spare parts. They have what seems to be a longish list, though unfortunately many of these items are marked "sold out". Some sources that I had obtained parts from seem to have dried up and as for recoil springs, a "wear item", I ended up having some made, I was able to furnish an unused recoil spring for the spring maker. In passing, the following might interest some. I had noticed evidence of frame battering in my M 30, looked around and couldn't find anyone who made "shock buff" type items. Perhaps I just got lucky, but it turns out that the buffer for the CZ-75, made by Buffer Technologies fits, and functions, it seems, without problems. If I understood correctly, and if the information itself is correct, I've been told that recoil springs for the CZ-75 will work in the M 30. I cannot confirm this however, though it might be worth that proverbial "college try".. As for magazines, S & W 5900 series are supposed to work, though the factory items, use of these is suggested, seem to have dried up, and after market magazines might or might not fit. Hope the foregoing helps.
