Proctor Y Notch Sights are designed to be Fast Accurate Easy. The main premise behind the design is allowing fast easy vision with less room for sight misalignment. The Y shaped notch allows fast vision and target acquisition and makes it very easy to visually center the front sight in the rear notch for optimal sight alignment. The sights have a black nitride finish, which is extremely corrosion and rust resistant and also provides very nice visual definition to the sights.
This is a rear sight only for 1911 or 2011 with Novak rear sight cut. Fitting is required and should only be done by a competent GUNSMITH
However due to the variations in manufacturing of 1911 and 2011 pistols I cannot guarantee what height front sight will work.
