SIG Pro


The SIG Pro is a series of semi-automatic pistols 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. Offerings in the series are chambered in.40 S&W,.357 SIG, or 9×19mm Parabellum. , only the SP 2022 variant was still listed on the SIG Sauer website. The SIG 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.

Variants

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

First generation

These offerings feature a proprietary SIG accessory rail. 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.
  • SP 2340 – chambered in.357 SIG or.40 S&W.
  • SP 2009 – chambered in 9×19mm.
  • * One model features a manual safety and shortened trigger.
  • SPC 2009 – compact version of the SP 2009, chambered in 9×19mm.

    Second generation

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