$50.99
Smith & Wesson N-Frame Adjustable Rear Sight Body – Model 27 Style
Part# N27kit162 | Model 27 Fine Checkered / Crosshatched Tang | Tang Width: 2.09"
This is a used rear adjustable sight body only — no blade, elevation screw, windage screw, or stud included. Parts are needed to complete a rebuild. Inspect the photo carefully and verify the 2.09" tang measurement matches your firearm before ordering.
This sight body features the distinct, classic Model 27 crosshatched/checkered pattern on the top of the tang, offering that highly sought-after vintage look and excellent glare reduction. It shares the exact same physical dimensions, screw spacing, and height as a standard factory N-kit, making it a direct mechanical drop-in fit for a wide variety of S&W N-Frame revolvers.

How to Find Your Model Number
Swing out the cylinder and check behind the yoke on the frame. Model numbers were introduced in 1957–58. If no model number is present, your revolver may pre-date 1957. Contact us with your serial number and we can help identify the correct part.
