Glock Slimline Trigger System (G43/43X/48)

The Trigger Shark slimline kit is the cheapest way to get an adjustable trigger into a Glock 43, 43X, or 48. It pairs a polished and mechanically modified trigger bar with a polymer shoe that has been laser-textured for grip and had its safety tab slightly trimmed to soften the press. The bar modifications target the drag where the bar rides over polymer and steel inside the frame, which is where the factory slimline trigger picks up most of its grit.

The hex screw is what separates it from a plain shoe-and-bar swap at this price. The kit ships with a hex key and a hex bit so the shooter can set reset and over-travel rather than accepting whatever the part arrives at. Trigger Shark also sells a separate slimline kit with a connector and a distinct G42 trigger, so check which product you are ordering: this row is the shoe-and-bar kit for the 9mm slimline guns.
