The Ruger SR1911 equipped with a factory cut front sight dovetail require a front sight with the correctly dimensioned and engineered dovetail to fit properly. The best front sight on the market is made by Dawson Precision and I am pleased to offer it to compliment my rear sight product line. The DP sights are machined from hardened steel and are serrated 50 lpi to enhance daylight visibility. They are offered in a height of .200" with a width of .125".
Important Note: Please read the "Do I need a new front sight" topic located in all of the sight category sections for details on how to select the correct height for your pistol.
