Warren Tactical Series-Sevigny Competition Sights for 9mm and .40 FNH FNS and FNX Pistols
Rear Sights- Plain black
- .125” wide notch
- .150” wide notch
Front Sights- Plain black and Fiber Optic
For most FNS and FNX pistols and ammunition we recommend .220” tall fronts. Point of impact (POI) with most 115 grain and 124 grain ammunition should be at or slightly above point of aim (POA) at 25 yards. We have found heavier weight bullets, 135 grain and 147 grain, will hit slightly higher than 115 grain and 124 grain with the .220” tall fronts at 25 yards.
- .105” wide x .220” tall
- .115” wide x .220” tall
- .105” wide x .240” tall*
- .115” wide x .240” tall*
We recommend a .240” tall front only if experiencing greater than a 3” point of impact with a .220” tall front at 25 yards.
There has been mixed POA/POI feedback for the respective front height selections. Our recommendation is the .220” because it is better for the bullet impact to hit slightly high at a given distance than to hit low.
Additionally, the shorter front will offer correction for those experiencing an unusually low POI with their pistol. Our goal is to help FNH customers get the best results with their respective pistol and ammunition.
All sight ratios allow for fast acquisition and precise alignment when engaging at speed.
Taylor your selection based on personal preference and type of shooting.
- .150” wide rear notch with a .115” front- Best for practical shooting, speed steel and target shooting. Fairly open sight picture.
- .125” wide rear notch with a .105” wide front- Best for practical shooting, speed steel and target shooting. Slightly tighter sight picture than the .150” rear/.115” front.
- .125” wide rear notch with a .115” wide front- Best for PAR-time shooting sports and target shooting. Tightest sight picture.
