The Compact PRO configuration delivers a balanced carry size with its 3.6 in barrel and compact grip module, while retaining a 15+1 capacity in 9mm Luger. The polymer frame is finished in black with molded texturing and SIG medallions for a secure, consistent hold.
The slide is matte black with front and rear serrations for confident manipulation. It is optics-ready and ships with a two-screw cover plate installed. Factory tritium night sights include a green-dot front marked TG-H3 and a matching tritium rear for clear, low-light aiming references.
Controls are straightforward and duty-focused, including ambidextrous slide-catch levers and a standard curved trigger. A MIL-STD-1913 accessory rail on the dust cover supports common weapon-mounted lights or other compatible accessories.
At the core is SIG Sauer's modular, serialized stainless-steel Fire Control Unit, paired with a stainless-steel receiver. Markings include the frame legend "NEWINGTON, NH, USA," and the magazines are stamped "MADE IN ITALY." Two 15-round magazines are included.
