Glock's collection of Slimline handguns are some of the most popular concealed-carry guns on the market today, and Apex Tactical has the perfect trigger-upgrade option available for these easily carried guns in the form of the company's Action Enhancement Kit designed for slim-frame Glocks. Each Apex Tactical Action Enhancement Kit includes the company's enhanced trigger, trigger bar and Apex Performance Connector. All of the components are direct, drop-in replacements of the factory trigger components, and the improved parts provide a smoother trigger pull with reduced trigger travel, a shortened reset and a crisp, clean break. Overall, owners of Glock®Slimline pistols can expect to see an improved trigger-pull weight of 5.5 pounds with the Apex Action Enhancement Kit, and the center-mounted pivoting safety on the Apex trigger ensures that all the safety elements included in the OEM Glock®pistol are preserved. This kit is designed for use on the Glock®G43, G43X and G48. It cannot be used on the Glock®G42.
