This Trijicon night sight kit replaces the factory sights on the Beretta BU9 Nano, the compact 9mm carry pistol Beretta built for concealment. It ships as a complete front and rear set, so a Nano carrier can swap both sights in one job rather than mixing components. The draw here is tritium illumination, which gives a usable aiming reference in low light without batteries or charging. For anyone running a Nano as a daily concealed-carry gun, factory sights are functional but the tritium upgrade is the standard move. You can compare other pistol options in our gun and bow sights selection.
Trijicon night sights use sealed tritium gas vials housed in aluminum sleeves, set inside a steel sight body. Tritium glows on its own through radioluminescence, so the dots stay lit in a dark room, a parking garage, or under a porch light with no external power. The vials carry roughly a decade of useful brightness from date of manufacture, which is typical of tritium illumination across the industry. This kit is cut specifically for the Beretta Nano slide, so the dovetail dimensions match without filing or fitting a generic blank. The result is a three-dot sight picture, front and rear, that aligns the same way in daylight and darkness. Carries MPN EU00038 and UPC 082442581705 for verification.
A buyer reaches for this kit when the Nano is the carry gun and the factory sights wash out in dim conditions. Tritium dots let you confirm your front sight on a target indoors at night or in the half-light around dawn and dusk, which is where most defensive shooting actually happens. Installation needs a sight pusher or a punch and a steady hand on the dovetails. If you carry a different Beretta, we also stock the PX4 Compact night sight kit and a 92FS and 96FS set from the same line.
This kit is cut for the Beretta BU9 Nano, the compact 9mm carry pistol. The dovetails are dimensioned for the Nano slide, so both the front and rear sight drop into the factory cuts without modifying a generic blank.
No. Tritium glows on its own through radioluminescence, so the dots stay lit with no batteries, charging, or light exposure. The sealed gas vials carry roughly a decade of useful brightness from the date of manufacture, which is standard for tritium across the industry.
It is a complete kit with both the front and rear night sights for the Nano. You replace both factory sights in one job rather than buying components separately and matching them up.
Installation calls for a sight pusher or a brass punch and a steady hand on the dovetails. The cuts are matched to the Nano, so no filing is required, but the press fit still needs proper tooling to seat the sights without damaging the slide.
