XL Optic Complement 3-dot sight set combining tritium illumination with white outlines — designed to complement an optic-ready slide where the irons need to be visible co-witnessed with the red dot. Tritium gives you night-visible dots; white outlines give you fast daylight pickup.

Specs:

• Reticle: 3-dot tritium + white outline
• Front sight height: .315"
• Rear sight height: .394"
• Configured for taller-than-standard slide cuts to co-witness with red dot optics

Co-witness behavior: Tall front and tall rear means you'll see the iron sight picture through the red dot window — gives you a backup aim point if the optic fails. Pair with an RMR or similar optic on a Glock or compatible pistol with optic-ready slide.
