The SIG Pro is a series of
semi-automatic pistols developed and manufactured by
SIG Sauer in
Exeter, New Hampshire. 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.[8]: 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.[9] The SIG Pro was marketed as a lightweight[10] and compact alternative to the "legacy" SIG Sauer handguns in an increasingly competitive and budget-oriented law enforcement market.
These offerings feature a proprietary SIG accessory rail.[11] 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.[8]: 78
One model (P2009-9-BMS) features a manual safety and shortened trigger.[14]
SPC 2009 – compact version of the SP 2009, chambered in 9×19 mm.[14]
Second generation
These offerings feature a
Picatinny rail, and a trigger guard that is visibly different than the first generation variants.[11] 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.[15]
SP 2022 – chambered in 9×19 mm, .357 SIG or .40 S&W.[16]
Some models (such as E2022-9-BSS-MS) are available with a manual safety.[17]
SPC 2022 – compact version of the SP 2009, chambered in 9×19 mm.[18]
