I recently picked up a Sig 250 in .380 with the med sized compact frame. I was wanting to know will a subcompact frame for a 9mm interchange with the .380? I have looked around and found no other frames mentioning the 380 only 45, 9mm and 40.

Yes - I have a .380 and had a 9mm - the grip modules are interchangeable as long as the module is for a 9mm/.357/.40. I think the .45 FCU and grip modules are different - but I'm not sure about that. I really like my .380, I was able to get a total of four Ital mags for it before the supply dried up.

Thanks for the info.

Yes, a subcompact 9mm grip module will work with a P250 .380 Compact.

The P250 Owners Manual shows that a .380 Compact uses the same length slide and barrel as a .380 Subcompact. The .380 Compact grip module is actually cut back to the length of a subcompact slide.

This isn't true, unless it's changed since I bought mine. It is true for the 320.

The 250 .45 grip module has a wider mag opening, but all the other calibers interchange. The firing mechanism is the same for all.
