Rival Arms RA2A231G Night Sights for Glock 42/43/48 - Green Tritium Orange Ring Front, Green Tritium Black Ring Rear

The Rival Arms RA2A231G night sights for Glock 42/43/48 are purpose-built replacements designed for shooters who demand reliable target acquisition in low-light conditions. These tritium night sights feature a green tritium front sight with an orange ring and a green tritium rear sight with a black ring—a classic high-visibility configuration that works equally well in daylight and darkness. Whether you carry a compact Glock 42, the slimline 43, or the newer 48, these sights deliver the same rugged dependability you'd expect from a reputable sight upgrade.

Tritium-based night sights eliminate the need for batteries or charging; the tritium capsules glow continuously, making your sights visible in complete darkness without a flashlight. The contrasting ring colors (orange front, black rear) help your eye naturally align the sight picture quickly, which matters when every millisecond counts. For defensive carry, home defense, or low-light training scenarios, this is the kind of no-nonsense upgrade that pays dividends the moment you need it.

Installation is straightforward—no gunsmith required—though proper sight pusher tools make the job easier. The RA2A231G is engineered for compatibility with Glock's standard slide design across these three popular compact and subcompact models. If your carry gun currently wears factory plastic sights, upgrading to tritium night sights is one of the most practical and cost-effective improvements you can make.
