Will a hk usp compact 357 sig mag work with 40 S&w ammo? I have a 40 cal usp compact and can get a good deal on some 357 sig mags if they will work.

My understanding is that they are the same. I used 357 mags in my compact 40 without any issue.

USPC .40 and .357 SIG mags are exactly the same. Use either interchangeably with complete confidence.

They will work flawlessly.
Now all you need is a 357Sig barrel.
I shoot 357Sig in my 40 compact magazines and haven't had any problems at all.
