How to replace your fiber optic strand
Pistol Sights w/ Dovetail
Once factory front/rear sights are removed, clean all surfaces on the slide and within empty dovetails. Use an alcohol based solvent to clean all gun oils and residues before installing new Williams sights.
!!! NOTE:: Aluminum sights will buckle and bend if not properly fitted. DO NOT use a sight pusher on aluminum sights!!!
With the slide locked securely in a vice with protective wood to prevent damaging the slide. Place the front/rear sight in the dovetail by hand to determine how much fitting will need to be done. Make sure the sight is going in the correct direction. The part of the sight with the exposed fiber optic showing will be pointed towards the shooters eye.
To determine how much fitting will be needed. The leading edge of the front/rear sight dovetail should be able to be inserted by hand about halfway into the pistol slide’s dovetail. If the sight’s dovetail does not then using a fine file, remove a thin layer of the dovetail on the bottom of the sight. Do NOT over file! Only remove a small amount at a time until the sight dovetail can be inserted half way in the pistol dovetail.
Once front/rear sight fitting is complete and placed in dovetail. Use a brass or nylon sight punch to insert the sight the remaining distance. The front/rear sight should be center within the slide for optimum shooting accuracy. Use calipers to verify.
