The Meprolight Tru-Dot Adjustable Sights (brand part number 227703101) are combat-proven, self-illuminated night sights built to dramatically increase hit probability on stationary or moving targets in low light. Built for Smith & Wesson K, L, and N frame revolvers, the Tru-Dot system gives a shooter three solid dots that look and sit identically whether it’s day or night, so there’s no mental transition needed between lighting conditions for rapid, instinctive aiming. Designed as a direct replacement for standard weapon sights, they mount with only minor modification.
