I have a 250 compact in 9mm.
Picked up .40 caliber compact exchange kit (came with 10 rounders).  Shopping for normal free state mags now.
I thought that the .40 mag for 320 carry / 250 compact frame took the same mag?  But looking into it, the p250 is (was) 13 and 320 is 14.

Is the 320 carry grip longer in .40?  So the 320 mags will extend out a bit on my 250?  Or were they able to stuff another round in there with newer mag version?

It also doesn't help that Sig changed the frame nomenclature compact to carry.  

I have 320 9mm carry mags that fit and work just fine in the 9mm config.

BTW love this pistol... I shoot revolvers as the good Lord intended and this is the  smoothest DA pull I know of.

So... I find comfort in the fact that if Trump has to work so hard to go to Heaven, then there is a shit load of Democrats that have no f-cking chance to go anywhere but HELL. Sometimes it is entirely appropriate to kill a fly with a sledge-hammer.

Ah, thanks.  I had an old man yelling at the clouds moment.

So, Sig added a grip/frame size with the 320.

I would assume that one of these would make the 14 round mags fit nicer.  Caliber wasn't specified in the description that I could see.

I googled for an image showing what I am looking for but did not find one.

I believe the carry gives you one more round of .40 than the compact.
