[ARCHIVED THREAD] - USP Compact .40 / 357 SIG

Posted: 10/21/2009 5:04:42 PM EDT

Fairly recently I bought a USP compact in .40 and I was curious if it would be compatible with .357 SIG if I picked up a new barrel. I am thinking it would be but I am not 100% sure. Any help would be appreciated, thanks!

All that's needed to convert a USPc 40 to .357 sig is a new barrel. Mags and all other parts are the same.

This.

I'm waiting for a barrel as well.

That's great to hear, thanks for the info fellas. Now this question might sound stupid judging from the previous posts. Today I was at my local range and they had some used HK USP compact mags in .357 SIG. I am guessing these would work with .40 since .40 works with .357 SIG. Thanks again!

IIRC, HK doesn't make USPC's in 357Sig anymore, just the barrels every now and then, so all you are going to find are ones either used or NIB at a distributers warehouse or a dealer.
