This Spectre Comp variant features a compensator that is cut directly into the slide, helping keep the muzzle flatter without adding length via a separate threaded device. The slide also includes Spectre milling with front and rear serrations, a lightening window, and a Nitron finish over stainless steel.
The 3.1-inch barrel and the flat-face trigger both wear a durable TiN coating. The trigger provides a consistent, striker-fired pull, and the pistol is configured without an external manual thumb safety.
SIG X-RAY3 day/night sights are installed, with the rear sight mounted on the removable optic cover plate. The slide is optics-ready, allowing a micro red dot to be mounted when the cover plate is removed.
The XL-size polymer grip module uses the XSeries LXG laser-engraved texture for a secure hold and accepts flush-fitting 12-round magazines. A SIG micro accessory rail on the dustcover supports compatible compact lights or accessories.
