The Sig Sauer 9/40/357 Compact Medium Grip Module in black (brand part no. GRIP-MOD-C-943-M-BLK) is a grip module for the P320 and P250 compact. Sig Sauer sets it up for 9mm, .40 S&W and .357 SIG, in a medium grip size. You install your P320/P250 firing control unit into it, which converts the pistol to a compact in those calibers. It requires the 9mm, .40 or .357 SIG slide and barrel. It is a straightforward way to change the size of a P320.
