"gb_in_ga, did you see the previous discussion of 10mm revolvers? "
Yes, of course I did. The subject has come up fairly often over the years. First, they aren't all that common. Second, the ones that do exist only exist as large, heavy frame revolvers. Third, I really, really, really don't like using moon clips.
None of those issues exist for the .357 Mags.
Ok, I'll give that the reason why they aren't all that common is that they aren't all that popular, and that part of the reason why they aren't all that popular is that they aren't all that common. Yeah, that's self referential. Recursive. But I still like having the options of having the round available in small and medium frame revolvers as well as large. And I still don't like moon clips. Oh, and because 10mm revolvers aren't at all common, neither are their moon clips -- which are required for use. Yeah, you can probably order them -- for now at least. Who knows what the future might bring?
