Built around XS's F8 philosophy—front sight focus in all lighting conditions—this set pairs a tritium-powered front dot with a shallow-V rear notch for quick target acquisition under stress. The front sight glows in low light without batteries or charging, while the rear sight's matte black finish eliminates distractions. Designed for defensive shooting, these sights prioritize speed over precision at typical self-defense distances.\u003c\/p\u003e\u003cp\u003eMachined from steel with a rust-resistant finish, the F8 set installs in standard Glock dovetails. The front sight features a protective ring around the tritium insert to prevent damage during holstering or daily carry. The rear notch is wide enough for fast alignment but shallow enough to keep your eye on the front dot. Sights are sold as a complete set for Glock 20, 21, and 29 models (large-frame 10mm\/.45 ACP). Professional installation recommended for proper fit and zero.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Tritium Night Sight Set\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFront Sight:\u003c\/strong\u003e Tritium Dot (Green)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRear Sight:\u003c\/strong\u003e Blacked-Out Shallow V-Notch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSight Picture:\u003c\/strong\u003e F8 (Front Focus)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Steel with Rust-Resistant Finish\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Models:\u003c\/strong\u003e Glock 20, 21, 29\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Dovetail Mount (Gunsmith Recommended)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUse Case:\u003c\/strong\u003e Defensive \/ Concealed Carry\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"XS Sights","offers":[{"title":"Default Title","offer_id":47940869521663,"sku":"XSSGL-F007P-5","price":109.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/1314857.jpg?v=1766567594","url":"https:\/\/doublestackstore.com\/products\/xs-f8-night-sight-for-glk-20-21-29","provider":"Double Stack Store","version":"1.0","type":"link"}
