Product DescriptionXS Sights F8 Night Sights are engineered for rapid front sight focus in all lighting conditions. A large, high-contrast front sight with an orange photoluminescent ring surrounds a green tritium vial, while the wide-notch rear sight features a green tritium lamp to speed alignment in low light. The rounded base of the rear notch draws your eye to the top edge for proper sight alignment, and the rear sight overhang helps reduce glare. A robust ledge on the rear allows onehanded slide manipulations. These sights install easily with hand tools or a sight pusher and fit common holsters. Compatible models include Sig Sauer P320, P229, P228, P226, P225; Springfield Armory XD, XDM, XDS, XDE; and FN 509.Product Highlights Green tritium front with high-visibility orange ring for fast daytime and lowlight acquisition Green tritium rear in a wide notch to enhance front sight visibility Rounded rear notch and overhang reduce glare and guide focus to the sight tops Rear sight ledge enables reliable onehanded slide manipulations Easy installation using hand tools or a sight pusher; fits common holsters Specs Product Type: Handgun night sight set Model: F8 Night Sights Front Sight: Green tritium with orange photoluminescent outline Rear Sight: Green tritium, wide notch Housing/Finish: Metal housing, matte black Compatibility: Sig Sauer P320, P229, P228, P226, P225; Springfield Armory XD, XDM, XDS, XDE; FN 509 Installation: Install by hand or with sight pusher tool UPC: 647533045773 MPN: SI-F012P-5 Brand: XS Sights Disclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
