These sights are for Magnum Research 1911's that have MR1911 engraved on the slide.
Is there really a difference with Dawson Precision sights? You bet there is! While other sights give off a hazy glow making it difficult to focus, DP sights offer you the sharpest picture. We counterbore the blade so the optic is recessed. This subtle difference focuses the light in the sight making it not only brighter, but clearer. A fully cradled optic provides a longer optic lifespan.
