I searched but didn't find my answer so here's a HK rookie question.
I saw a local ad for a lnib used P2000 .357 at a pretty decent price. With the .357 phased out will there be a problem getting magazines in the future? I've seen ads for .357 mags and for .40 mags so I'm guessing the .40 mag doesn't work with the .357 SIG.
