Designed, machined, and tested by ZRTS, this sight is a drop-in replacement for any Sphinx SDP rear sight. We call this a hard use/duty sight as it’s billet steel machined with a ledge for racking and a U-notch for fast target acquisition. Ears of the sight are bobbed at 45 degrees to reduce snags and to direct your eyes to the center of the sight. We matched the rear curve of the slide for a perfect, clean fit. Fit and finish is on par with the Swiss pistols themselves! Works with our Sphinx SDP fiber optic front sight OR factory front sight. Available with 50LPI serrations or smooth.
Fits: SDP Compact, SDP Duty, SDP Subcompact!
Will also fit 1911s with Novak rear cuts!
