Williams target pistol Firesights feature a unique click adjustment design for both windage and elevation adjustments.  This unique design provides a crisp click when adjusting the sight, so the shooter is aware of each click adjustment for precision accuracy.  These sights also feature Williams high visibility fiber optic design for precision shooting in low light scenarios which is perfect for dim shooting ranges or out in the field hunting.  Every sight is CNC machined out of high grade aluminum and steel for a sight that holds true in all shooting scenarios.  All Williams products are USA made.
