The Truglo TG131S2 is a fiber-optic front and rear sight set engineered for Sig Sauer P-Series pistols. It uses traditional fiber-optic elements to create bright, contrasting aiming points — a red front dot paired with green rear dots — for quick sight acquisition in variable lighting. The sights are CNC-machined from steel and finished with Truglo’s Fortress coating for durable corrosion resistance. The concealed fiber design reduces visibility to the target while maintaining high visibility for the shooter, and the snag-resistant profile is compatible with standard holsters.
