Glock sight sets pair matched front and rear units calibrated for competition use across Production, CO, and IDPA divisions. Dawson Precision sets dominate at the GM level for a reason — height combinations are dialed for standard and major/minor power factor loads, and fiber-optic fronts paired with notch rears deliver fast, repeatable sight pictures at USPSA field course distances. Sets eliminate the guesswork of mismatched aftermarket combinations. Fast same-day shipping on most orders at Shooters Connection.
