The SIG Pro is a series of semi-automatic pistols manufactured by SIG Sauer in Exeter, New Hampshire.^[8]^[9] It became 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.^[10]^: 78 Offerings in the series are chambered in .40 S&W, .357 SIG, or 9×19mm Parabellum. As of March 2020^[update], only the SP 2022 variant is still listed on the SIG Sauer website.^[11] The SIG Pro was marketed as a lightweight^[12] and compact alternative to the "legacy" SIG Sauer handguns in an increasingly competitive and budget-oriented law enforcement market.

Variants

There have been two generations of SIG Pro offerings, with five total variants.^[13] The below are each hammer-fired semi-automatic pistols operating in double action / single action (DA/SA), with a decocker and without a manual safety, unless noted otherwise.

First generation

These offerings feature a proprietary SIG accessory rail.^[13] It was originally developed as a .40 S&W caliber service pistol and introduced in June 1998, followed shortly by a version in .357 SIG. About a year later, a 9×19mm Parabellum variant was introduced and entered production in response to demand for the type.^[10]^: 78

SP 2340 – chambered in .357 SIG or .40 S&W.^[14]
SP 2009 – chambered in 9×19mm.^[15]
- One model (P2009-9-BMS) features a manual safety and shortened trigger.^[16]
SPC 2009 – compact version of the SP 2009, chambered in 9×19mm.^[16]

Second generation

These offerings feature a Picatinny rail, and a trigger guard that is visibly different than the first generation variants.^[13] The design was selected in 2002 as a new service pistol for French police, intended to have a 20-year service life (until 2022), hence the model number.^[17]

SP 2022 – chambered in 9×19mm, .357 SIG or .40 S&W.^[18]
- Some models (such as E2022-9-BSS-MS) are available with a manual safety.^[19]
SPC 2022 – compact version of the SP 2009, chambered in 9×19mm.^[20]
