Smith & Wesson Rear Sight Height Chart

graphic

The Bowen Classic Arms Rough Country rear sights for Smith & Wesson revolvers are available in three heights that correspond closely to the factory-supplied sights, well within the operating ranges of the respective rear sights. The factory sight heights are usually cited for just the blades rather than the whole sight body/blade assembly. Bowen Classic Arms sight heights are the working heights.

The S&W heights and corresponding Rough Country heights are as follows:

S&W .126 uses BCA .370
S&W .146 uses BCA .385
S&W .160 uses BCA .400
S&W .196 uses BCA .430

To select the Rough Country sight for your gun, use the chart below.

Please note: There are hundreds of Smith & Wesson models and variations with more on the way very day so this chart may never be complete. Some of the PD-series guns are equipped with V-notch rear sights but also with fiber-optic front sights which will probably work better with square-notch/white-outline rear sights. As time permits, we'll try to develop a conversion chart for these models.

A glaring exception to the Old-Style/New-style standards are some of the Model 625-5, Model 29, and Model 629 DX-Classics , which have a hybridized setup employing Old-style sight parts on New-style receivers. These sights must be made on a custom one-off basis.

* Factory sight height does not have direct correlation. Selecting most appropriate blade will depend in on actual front sight height.

** Factory height lies outside the range of known correlation. Please call our parts line for assistance in selecting the appropriate part. (865) 981 8869
