Ruger one hole sight

[AL45]

Is anyone familiar with the Ruger one hole peep sight from Warren Outdoor Products? Apparently it can be mounted on a Ruger Blackhawk. Some who have used them say it improves accuracy and speeds up target acquisition.

Generally speaking that is true but you'll also find that some Ruger's & BFR's will need a front sight change, as the one-hole sight sits just a tad higher than your factory notch and your revolver just might not have enough elevation adjustment to bring the POA and POI together.
