Aiming a pistol under normal daylight conditions and hitting the target requires minimum effort. But. . . , under low light conditions, standard sights become ineffective. FBI statistics indicate that 80% of officer shooting injuries take place in low-light or no-light conditions. Painting three white dots on the sights offers only marginal improvement. Meprolight's solution is to supplement or replace the painted white dots with small self-contained tritium lights that enhance shooter capability under low-light conditions.
Meprolight Tru-Dot models offer a handgun sighting system for improved rapid instinctive aiming which requires no transition from day to night use. Day and night, the shooter's aiming reference are three solid dots, identical in appearance and location under all light conditions.
