Hey guys did a search but couldn't find an answer for sure.
I have a P250C in 40 S&W, which I really like.
Looking at a P320C in 9mm.
Can I exchange barrels and mags between the two frames.
In other words, can I put my 40 barrel from the 250 in the 320 chassis?
Thanks for the help, and sorry if it's been asked before.

I don't see why you can't. I would bring the barrel to your FFL and see. I think you'll pique their interest in where they'll try to fit it in the p320.

My only concern is heaspacing. Though I think they're reamed out the same.

I think I figured it out.
40 and 357 can do a barrel swap.
9mm to either of the above also needs a slide assembly.

Correct.

The .40 and .357 barrels are interchangeable but have a larger OD than the 9mm. They will not fit in the slightly smaller muzzle bore on a 9mm slide.
