Ameriglo SG301 i-Dot Night Sight Set for SIG Sauer - Green Tritium LumiGreen Outline Front / Green Tritium Rear

The Ameriglo SG301 i-Dot Night Sight Set brings Ameriglo's distinctive dot-over-dot aiming concept to SIG Sauer pistols. By stacking a single front tritium lamp over a single rear tritium dot, the i-Dot layout creates a clean vertical sight axis that the eye picks up faster than a conventional three-dot pattern - the kind of speed advantage that matters when presentation time is short and lighting is poor.

Both lamps are charged with green tritium for continuous, battery-free illumination that stays bright in dim rooms and total darkness. The front sight is wrapped in Ameriglo's LumiGreen outline for an extra hit of visibility against dark backgrounds, while the rear sight uses a snag-resistant green tritium single-dot notch for an uncluttered sight picture.

Sight housings are machined from steel and finished in black to stand up to daily carry, repeated draws from a holster and full-power pistol recoil. The SG301 is cut for SIG Sauer pistols that take #8-height front and #8-height rear dovetails, making it a direct replacement for the factory iron sight pair on most popular defensive-size SIG slides.
