Well, I was thinking about it, and the 10mm MPP should really be firing 9mm rounds (or even crappy 8mm like the Nambu). It doesn't look beefy enough for 10mm. Of course, there's way too many references to it IC to make retroactive changes. For the record, the Type 28 and 28A GSPs are no longer produced either; the 28B, hoever, is still being made and would be the most likely candidate to replace the 28 MPP.
The Free 10mm Pistol Offer is still limited to one per soldier.
