The SIG Sauer P250 is a semi-automatic pistol made by SIG Sauer of Exeter, New Hampshire. The SIG P250 can be chambered in .22 Long Rifle .380 ACP, 9×19mm Parabellum, .357 SIG, .40 S&W, and .45 ACP. The P250 chambered in 9×19mm Parabellum was introduced to the North American market on November 7, 2007 followed by the .45 ACP compact model in February 2008 at the SHOT Show. The last of the models were introduced in late 2009.

In early 2014, the SIG P320 was introduced. This striker version of the P250 continues the modular format and shares several of the same components as its hammer-fired sibling including magazines and grip frames.

As of January 25, 2017 the only available caliber for the P250 on both the SIG Sauer website and their online catalog is the P250-22 Nitron Compact .22 Long Rifle. Exchange kits can convert the P250 from .22 Long Rifle to 9mm, .357 SIG, .40 S&W and .45 ACP.

The P250 pistol is a short recoil operated, locked breech pistol. It uses the SIG Sauer locking system in which an enlargement of the chamber locks into the ejection port on the slide.

A key feature of the pistol is its modular design. The main module of the P250 is an internal stainless steel frame fire control unit which consists of the integrated fire control group (trigger, hammer and all necessary linkage and springs), ambidextrous slide release (one on each side of the pistol), ejector and four slide rails. This steel receiver unit is used in every P250 grip module, top end, and chambering combination and is inserted into the grip frame module and held in place by the axis pin of the disassembly lever. The firearm's serial number is on the fire control unit instead of the grip module. The fire control unit allows the operator to interchange differently-sized slide assembly or top end modules and polymer grip frame modules and trigger shoes and (limited) chambering conversions to adapt the gun to the individual user and address different needs.
