Originally produced for police and government contracts, this Pro-series pistol left the factory under a law-enforcement allocation and is now available to the public only through secondary channels. Its Agency Vault provenance adds collectability while guaranteeing genuine duty-grade build standards.
The serialized stainless-steel fire-control unit is the core of SIG’s modular system, allowing caliber or grip-module swaps without additional paperwork. Out of the box, it wears the X-Series full-size medium grip module with an extended beavertail, deep trigger-guard undercut, and aggressive molded texture for confident control.
A flat-faced X-Series trigger offers a straight press with an approximate 90-degree break, helping shooters achieve consistent, repeatable shots. The reversible magazine release supports left- or right-hand operation.
The carbon-steel slide is Nitron finished for corrosion resistance and sports both front and rear cocking serrations. Its factory Pro optic footprint accepts the SIG ROMEO1 PRO, ROMEO2, and Leupold DeltaPoint Pro without adapter plates, streamlining red-dot installation.
Tritium-powered X-RAY3 sights pair a high-visibility green front ring with a serrated two-dot rear, delivering a clear sight picture in daylight and darkness alike. Three 17-round magazines provide ample on-board capacity for range, duty, or home-defense roles.
