Dawson Precision Glock sight sets pair front and rear units pre-selected for accurate point-of-impact at USPSA field course distances. Fiber-optic fronts in calibrated heights with matched fixed or adjustable rears take the calculation out of sight selection — each set is built for specific Glock models and power factors. No mismatched dovetails, no elevation compromise. The choice of Production and CO Grand Masters for over two decades. Fast same-day shipping on most orders at Shooters Connection.
