    If you have a 22/45 with factory sights , you need these. They make it so much easier to get on target day or night.

    No replacement of dovetail needed

    I got these FO sights today and was a little worried how to change the rear sight since this sits very tight.. Then I saw that the Williams sight and the original Ruger sight are identical, except for the fiber optics. I just needed to remove 1 screw and replace the original blade with the Williams fiber opitics blade. So: No removal of the dovetail, no hammering, no gunsmith. Great product! :-)

    Works Great

    Just finished installing these. Took a modest amount of fine filing to get the new one to slide in. No instructions included so install from right side of upper. A tip: use a small piece of scotch tape on the right-side face to protect the finish when you use a drift to seat the rear sight. They are bright and easy to quickly align.
