The SIG Sauer Pro is a series of semi-automatic pistols developed by SIG Sauer in Exeter, NH, USA. It was the first polymer-frame handgun from SIG Sauer and one of the first pistols to feature a built-in universal accessory rail and interchangeable grips.
The SIG Sauer Pro was marketed as a lightweight and compact alternative to the "legacy" SIG Sauer handguns in an increasingly competitive and budget-oriented law enforcement market. It was originally developed as a .40 S&W–caliber service pistol and introduced in June 1998 with the SP 2340 model, followed shortly by a version in .357 SIG (which retained the same model designation). About one year later, a 9×19mm Parabellum variant, the SP 2009, was introduced and entered production in response to demand for the type.
All SIG Sauer handguns created since 1990 have been designed and manufactured by SIG Sauer in New Hampshire. Some are exported to SIG Sauer of Eckernförde, Germany.
The frame is made from polymer, with detachable grip panels. Grip panels can be easily replaced and are available in several different sizes and shapes.
The standard SIG Pro does not have a manual safety but it does incorporate a decocking lever (lowers the hammer without striking the firing pin), trigger-bar disconnect (disconnects the trigger when the slide is out of battery), automatic firing pin lock (does not free the firing pin until the trigger is depressed) and a hammer safety intercept notch (prevents the hammer from striking the rear of the firing pin until the trigger is depressed).
The Sig Pro comes standard as a double-action/single action pistol with 10 lb and 4.5 lb trigger pulls, respectively. Double-action only conversion kits are also available from SIG.
- SP 2340: The original pistol introduced in 1998. It has a rounded trigger guard and is chambered for .40 S&W and .357 SIG.
- SP 2009: 9×19mm Parabellum version announced in 1999.
- SPC 2009: A shorter version of the SP 2009 with a 3.58" barrel length and only available in 9 mm. It is equipped with the SIG accessory rail system and the trigger guard is rounded. This is the basis for the SPC 2022
- SP2009-9-BMS: A variant of the standard SP 2009 with a slide-mounted manual safety and short trigger. These were offered for a short time to the U.S. civilian market.
- SP 2022: A modified version of the SP 2009/2340. It entered service with the French Police, Customs, Penitentiary administration and Gendarmerie in 2002 for a planned service life of 20 years, hence the name. 460,000 rounds have been used for testing it before adoption by a sampling of future users and modifications of the SIG Pro followed to produce the 2022. It is available in 9×19mm, .40 S&W and .357 SIG. The pistol is fitted with an integral Picatinny rail instead of the proprietary rail of the other models and the front trigger guard is shaped differently so as to allow a finger hold. It can also be equipped with a threaded barrel and detachable suppressor and the fixed open sights are dovetailed into the slide.
- SPC 2022: A more compact version of the SP 2022 that is only available in 9×19mm. The SPC 2022 has a slightly shorter barrel and slide, as well as flat magazine base plates which make its grip shorter by 7 mm. It is equipped with a Picatinny rail and a finger groove trigger guard.
