Overview
This fixed rear sight is built for shooters who want a straightforward, low-profile aiming solution for concealed carry, duty, or other hard-use pistols. Its .140" U-notch and plain black blade are designed to provide a clear sight picture while staying compatible with a wide range of factory-height front sights, including fiber optic, tritium dot, and gold bead styles. Rounded, chamfered edges help reduce snagging on holsters, clothing, and gear during the draw. It is a practical choice for a pistol setup where a rugged rear sight and quick alignment matter more than added complexity.

Considerations & Trade-offs
- The .140" U-notch offers a specific sight picture that may not suit shooters who prefer a narrower or more open rear notch.
- It is a fixed rear sight, so it does not provide on-the-fly adjustment for changing loads or zero preferences.
- Fit is limited to Novak-style 65° x .500" dovetails, so compatibility depends on the pistol’s existing cut.
- The plain black rear blade is designed for a glare-free sight picture, but it does not include a contrasting rear insert or illuminated reference point.
