I can't speak to the Massachusetts gun laws and the likelihood of guns being added to the roster, but I do carry a P30 a fair amount. I'm 6' 190 so I guess I'm medium build-ish. Concealment has never been an issue with the P30. It carries well OWB or IWB, just be aware that the grip texture is pretty rough so I never carry it against bare skin. I carry the P30 more in cooler months when I can go with layered clothing.
You'll hear guys on here tell you to get both, and in this case I do recommend it. The P2000SK is the perfect summer carry gun. It can just disappear under just a t-shirt. Finding one in .357 SIG is going to take a little time though. If you find one and get a P30 in .40 then you can use the same magazine in both pistol (P30 magazines will fit in the P2000 series.)
Are any USP series guns on the roster?
