Product DescriptionXS Sights tritium night sights deliver a traditional 3dot, notchandpost sight picture designed for fast, confident shooting in both bright and low light. The rear sight is blackedout to boost contrast against the highvisibility front, which uses Ember Glow Dot technology to absorb ambient light and shine in dim conditions. Tritium lamps in the front and rear provide a reliable glow for sight alignment, while the durable CNCmachined steel construction and userfriendly installation make this set a smart upgrade for Glock smallframe pistols.Product Highlights Tritiumpowered front and rear lamps for lowlight visibility Highcontrast front with Ember Glow Dot for rapid target acquisition Blackedout rear with antiglare features to enhance frontsight focus Durable CNC steel housing with rear ledge for onehand slide manipulation Easy installation with hand tools or sight pusher; backed by a 10year warranty Specs Brand: XS Sights Manufacturer Part Number: GL-R012P-6G UPC: 647533046459 Sight Type: Tritium 3dot night sights, notch & post Front Blade Width: 0.145 in Rear Notch Width: 0.170 in Overall Height: 0.215 in (front), 0.320 in (rear) Material: Steel with tritium lamps; Ember Glow Dot front Installation: By hand or sight pusher tool Compatibility: Glock 17/17L/19/26/34 (9mm); Glock 22/23/27/24/35 (.40 S&W); Glock 31/32/33 (.357 SIG); Glock 36 (.45 ACP); Glock 38 (.45 GAP) Disclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
