These replacement iron sights feature a glowing focus-lock ring front sight for fast target acquisition in any light condition, plus a U-notch rear with a contrasting orange ring. The front sight is encased in a protected TFO capsule that houses both tritium vials and a fiber-optic rod, providing consistent visibility from dawn to dark.\u003c\/p\u003e\u003cp\u003ePrecision CNC-machined from steel, these sights are designed as a direct drop-in replacement for factory Glock 42 sights. Installation requires a sight pusher tool or professional fitting. The rear sight features an angled edge for emergency one-handed slide racking. The tritium inserts are Swiss-made with a rated lifespan of 12+ years, and the fiber-optic rods gather ambient light during the day for maximum brightness without batteries.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Tritium Fiber-Optic Hybrid Night Sights\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSight Configuration:\u003c\/strong\u003e 3-Dot with Focus-Lock Front Ring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFront Sight:\u003c\/strong\u003e Green Tritium + Green Fiber-Optic with Orange Ring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRear Sight:\u003c\/strong\u003e Green Tritium with U-Notch and Orange Accent\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTritium Lifespan:\u003c\/strong\u003e 12+ Years\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction:\u003c\/strong\u003e CNC-Machined Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecial Features:\u003c\/strong\u003e Angled Rear for One-Handed Cocking\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearm:\u003c\/strong\u003e Glock 42\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Sight Pusher Tool Recommended\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRUGLO","offers":[{"title":"Default Title","offer_id":47940223598847,"sku":"TG13GL3PC","price":133.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/1296330.jpg?v=1766554814","url":"https:\/\/doublestackstore.com\/products\/truglo-brite-site-tfx-pro-for-glk-42","provider":"Double Stack Store","version":"1.0","type":"link"}
