Rival Arms Tritium Night Sight Set for Glock 42/43 - 3-Dot Green

The Rival Arms Tritium Night Sight Set for Glock 42/43 brings dependable low-light performance to two of the most popular concealed-carry pistols on the market. This three-dot night sight system uses tritium luminous elements to keep your sights visible in complete darkness—ideal for defensive shooters who train after sunset or need to be ready any time of day. The green tritium vials provide the quick target acquisition and sight picture consistency that matter when speed counts, whether you're at the range, in competition, or depending on your gun for personal protection.

Built by Rival Arms, these sights pair a white front sight ring with a black nitride finish on the rear sight, giving you a classic high-visibility setup that works in daylight and low light alike. The white ring on the front sight helps you drive your sight picture in bright conditions, while the tritium glows when the sun goes down. The nitride-finished steel construction is corrosion-resistant and tough enough for hard carry and frequent training.

Drop-in compatible with both the Glock 42 (.380 ACP) and Glock 43 (9mm), these sights are purpose-built for the micro-compact platform. If you run a G42 or G43 and want better low-light capability than factory plastic sights, this is a straightforward, proven upgrade.
