Trijicon designed this HD XR Front Sight for Sig Sauer 9mm/.357 Pistols as the next level of advanced target identification and engagement at increased distances. This thinner sight post allows shooters to have a larger field of view that enhances their ability to identify targets, expedite engagements, and see hits at longer distances. The device features a green battery-free tritium phosphor lamp surrounded by a photoluminescent yellow outline disk. For durability, the lamp is encapsulated in an aluminum cylinder with a silicone rubber cushion, and covered with a sapphire window. The window acts as a beam-shaping lens and protects the lamp from solvents that are commonly used to clean firearms.

    Q: 9. do this expire like the x rite color checker?

    A: The packet comes with a sticker recommending to replace it after 18 to 24 months. If you can keep it in its pouch like a vampire keeps to his coffin when not in use, it should be OK from fading for longer than that. I suppose it depends on whether you have it out constantly in the light or not and how roughly it is handled. It's sturdy but the surface must be protected.
