Which front sight height will work with the Yost Retro rear sight?
It’s not really possible to say what front sight height will be required for every pistol as each gun can be different as there are many variables that will determine exactly what height front sight your particular gun will need. That said, the Yost Retro rear sight was designed to work with the stock front sight height on the current Colt 1911 pistols, .175″. Additionally, if your existing rear sight is the same height as the Retro rear and your gun currently shoots POA/POI then your front sight height will remain the same.
