Factory fixed tritium night sights (3-dot) are steel and dovetailed front and rear, with the rear unit marked MH3 AQ. The sight radius measures 5.8 in, supporting confident alignment in varied lighting conditions.
The serialized, removable fire control unit (FCU) carries an Exeter, NH rollmark and is housed in a textured polymer grip module with SIG SAUER molded panels. Controls include ambidextrous slide-catch levers and a reversible magazine catch for flexible setup. This pistol is the non-manual-safety configuration.
Practical slide features include front and rear cocking serrations for positive manipulation. A 4-slot Picatinny/M1913 rail on the dustcover accommodates compatible accessories. The barrel is steel, and the action is striker-fired for consistent operation.
Identified by manufacturer part number L320C-9-BSS and made in the United States, this example aligns with SIG’s Compact lineup and includes the original case and manual for straightforward ownership.
