    The black grip module is glass-reinforced polymer with molded SIG SAUER logos. A MIL-STD-1913 accessory rail with four slots is integrated into the dustcover for mounting compatible accessories.

    Markings and packaging details include "NEWINGTON, NH, USA" on the pistol and a factory case label dated January 17, 2022. The magazines are steel-bodied and marked "MADE IN ITALY." The mfg part number is 320C-9-B and the UPC is 798681505951.
