From David's website:
Quality made in the USA, these sights stay where you set them!
Mahan sights are precision made from a billet of 6061 aluminum stock and black anodized for anti glare and corrosion resistance. They will not shift like the stock plastic Hi-Point sights and are adjustable for windage and elevation. They will fit all four models of Hi-Point pistols (.380, 9mm, .40, and .45).
The design intent is to provide precision pointing as well as rapid target acquisition. These sights are 100% American made on 100% American made machine tools.
