.357 SIG in .40 S&W USPc mags??

[guy293]

Did a search, but wondering if anyone knows if 357 SIG rounds will fit and cycle in the .40 cal H&K USPc mags??

Thanks

They should. Wouldn't use them for self defense though.

they are the exact same mags for the .40/.357 for the USP-C with the exception of the stamp on the mag which says .40C or .40 compact or .357. otherwise identical.

I read over at HKPRO that the mags are different.

IIRC, the consensus was that you could reliably use .40 ammo in the .357 mags, but not the other way around.

(Keep in mind this is internet rumor working here, so??)

I'm holding out for 12 rnd .357 SIG mags for my USPc. I wish HK would get crackin on making standard cap mags.
