Description

Fits ALL Ruger Mark Series Pistols (see notes below)
Ruger “LITE” is still a Mark series pistol

V-Blade with White Line (Black .125″ ships on most Mark Pistols)
Adjustable for elevation and windage

Very early “Standard” pistols had a narrower rear sight dovetail, it is obviously smaller than later models, no measuring should be required to verify if comparing any MK2, MK3 or MK4

If your pistol has a NON-Adjustable rear sight, you will most likely need a taller front sight if installing this adjustable rear sight.
