The Ed Brown EVO series pistols allow the user to change the front sight, much more easily than the traditional dovetail setup. We have seven different front sight options to suit any need. Front sight height is 0.180″. Includes screw. We recommend our EVO front sight change kit, available for purchase separately, which includes the correct TP6 Torx+® wrench, spare sight screw, and purple Loctite®.
