A friend of mine found a good deal on one of these in 380acp. My question is if it's "modular" what part would he need to go to 9mm? Would it just be a barrel and mag? The only kits I see are for pretty much everything except the trigger group and cost more than he paid for the gun in the first place.

Caliber change in the P250 is usually accomplished with an 'X-change kit' which includes a barrel, a slide with recoil spring, a magazine or two, and the plastic grip frame.
The plastic grip frame is the same for 9mm, 40S&W, .357Sig, .380, and .22. The frame is different for 45acp.
In addition to changing the caliber you can also change the gun from subcompact, to compact, to full-sized. You can mix and match, too - running a compact slide over a subcompact frame is a popular combination.
Finally, the grip frames themselves come in three different hand sizes - small, medium, and large.
Sig designed this wonderful system and then, as you pointed out, stupidly made the price of the X-change kits far too high. The whole concept fails if the price of the kit is comparable to the price of a brand new pistol, but I never took a marketing class so maybe I'm missing something.
So, to answer your question, you'll need a barrel, a slide with recoil spring, and a magazine. Or you can get an Xchange kit, and just sell the duplicate plastic grip frame on ebay.
It's expensive but at least you don't have to go through an FFL.
Very informative. Thanks for the detailed response.
Slide and mags. The .380 slide has a lot cut out to get it to run. Was literally one google search my dude.
Also a barrel.
Tried google first thanks for the info
