Glock, Model 42 Rear Sight, .380 Auto, Slim Polymer Fixed 6.1mm Rear Sight

The slim polymer fixed 6.1mm rear sight for Glock Model 42 brings a low-profile, durable aiming reference to the subcompact .380 Auto platform, offering a subtle sightline that stays out of the way for concealed carry and tight-draw holstering while providing reliable sight acquisition on the range. Built from impact-resistant polymer, this fixed rear sight resists snags and absorbs recoil shock, making it well suited for everyday carry, training sessions, and follow-up shots during defensive scenarios. The 6.1mm width gives a narrow sight picture that pairs well with standard Glock front sights to promote quick alignment at close to moderate ranges, and its slim footprint complements the Model 42's small-frame ergonomics so holster fit and concealment are not compromised. If you run routine practice, carry daily, or need a low-maintenance sight that stands up to pocket carry and repeated use, this OEM-style Glock rear sight offers a practical upgrade for shooters who want consistent performance without altering the pistol's profile.
