Are P320 barrels interchangeable with P250, for example, would a P320 356 Sig barrel work in a P250 40 cal of the same grip module size? Thanks!

Just to clarify numbers, you mean .357 SIG and .40 S&W, right? Everything I've read leads me to believe they'd be a direct swap, although I've never actually done it. It's really the slide size rather than the grip module size that matters. (That might sound like a distinction without a difference, but some people put full-size slides on compact grip modules, for example.)

Yes, I believe the barrels, recoil assemblies, and grip modules are interchangeable.

Yes, you can swap the .40 and .357 SIG barrels on all SIGs. You can use the .40 or .357 SIG mags with .40 or .357 SIG ammo, but only .40 mags with .40 ammo.

Could you clarify? The last part seems to contradict the first part, but maybe I'm reading it wrong.

I believe the 357Sig marked mags have a taper that prevent use with 40 ammo.
Mags marked 357Sig/40S&W work with both calibers.

I've not seen P320 mags marked solely 40 or 357, though. All the ones I had were marked with both calibers

He may be referring to the P226 mags. I have a few that are marked as 357 Sig only.
