A tritium front lamp provides 24-hour illumination, while the yellow photoluminescent outline absorbs ambient light for instant target acquisition in varied lighting. The wide U-notch rear sight allows rapid sight alignment under stress.\u003c\/p\u003e\u003cp\u003eThese sights are purpose-built for the Glock 21 (.45 ACP) and install using a standard sight pusher tool. The front sight features a taller profile to clear suppressor-height optics when co-witnessing. Steel construction with a matte black finish resists corrosion and wear from holster draw cycles.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Tritium Night Sights (3-Dot)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTritium Color:\u003c\/strong\u003e Green\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFront Outline:\u003c\/strong\u003e Yellow Photoluminescent\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRear Sight Design:\u003c\/strong\u003e Wide U-Notch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSight Height:\u003c\/strong\u003e Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Models:\u003c\/strong\u003e Glock 21\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction:\u003c\/strong\u003e Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Matte Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Requires Sight Pusher Tool (Front \u0026amp; Rear)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Trijicon","offers":[{"title":"Default Title","offer_id":47940659478783,"sku":"TRGL104Y-600545","price":143.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/1308737.jpg?v=1766564990","url":"https:\/\/doublestackstore.com\/products\/trijicon-hd-ns-for-glk21-ylw-outline","provider":"Double Stack Store","version":"1.0","type":"link"}
