The HiViz GLFD21 FastDot H3 sight set transforms target acquisition speed on Glock pistols with its high-contrast red fiber optic front sight and green tritium rear configuration. This combination delivers exceptional visibility in both daylight and low-light conditions without requiring batteries or external power sources.
What Makes This Different
The FastDot system uses a larger, more visible fiber optic rod compared to standard three-dot configurations, creating faster sight alignment through improved contrast. The green tritium rear sight provides a subtle glow that won't overpower the bright red front dot, while the H3 tritium intensity ensures 12-year visibility in darkness. This asymmetrical color setup reduces confusion during rapid target engagement.Key Features
