I am very fond of the 940s and own several
I have rechambered my 940s for 38SUPER. Of course they can still fire all the other shorter cartridges . . . 38ACP, 9x21, 9MM Parabellun, 380ACP and more.
I also have some of the Performance Center 940 Specials. They are chambered for the much more powerful 356TSW cartridge.
While that asking price is high, I do not think it is WAY High. These do not turn up that often. 940s were only made for about a decade. The production was not as limited as some might assume, it is just that folks that own them tend to keep them. 940s were made for about a decade in both 2" and 3" configurations
Extra moon clips are not a problem, I think that even S&W still lists them on their site. If not, there are several other sources.
I have a butt load of moon clips.
The night before going shooting I will load up 20-30-40 or more so I do not fiddle with them on the firing line.
