The P250’s modular design centers on a serialized stainless-steel fire-control unit, with the EXETER, NH marking adjacent to the FCU window. This design approach provides a durable stainless receiver core within a polymer grip module.
The full-size configuration uses a 4.7-inch barrel and a stainless-steel slide finished in Nitron. The slide has rear cocking serrations and fixed, contrast-style sights: a dovetailed front blade with a white dot and a dovetailed rear square-notch.
The black polymer frame includes a full-length MIL-STD-1913 accessory rail on the dust cover for mounting compatible lights or other accessories. The pistol operates with a double-action-only trigger and an internal hammer-fired system.
Two steel magazines are included, one 14-round and one 10-round, each with witness marks and stamped "MADE IN ITALY." Stated capacity is 14+1 with the 14-round magazine.
This P250 is part of SIG Sauer’s discontinued P250 family (discontinued by 2017) and is U.S.-made. Core materials include a stainless-steel receiver (FCU), a stainless slide with Nitron finish, and a polymer frame in black.
