Action Enhancement Kit for Slim Frame Glock®

Description

Your slim frame Glock® deserves a trigger that keeps up with Arizona conditions—dust, heat, and hard use. The Action Enhancement Kit for Slim Frame Glock® from Apex is built for shooters who demand reliability when the mercury hits 120°F and the air is thick with fine desert dust. Priced at $135, this drop-in kit delivers a measurable performance upgrade without gunsmithing.

This kit pairs the Apex Action Enhancement Trigger (with trigger bar) and an Apex Performance Connector. Together, they reduce pre-travel, overall trigger travel, and reset distance—giving you a shorter, more controlled stroke. The break is a clean rolling pull at approximately 4.5 lbs., with smooth uptake and a positive reset that helps you stay on target during follow-up shots. The center-mounted, pivoting safety maintains factory safety values, so your carry gun stays safe.

Every Apex trigger kit is drop-tested from 6 feet onto concrete in 27 orientations, plus an additional 6 drops each at high (120°F) and low (0°F) temperatures. That means this kit is proven to function in the extreme heat of an Arizona summer and the cold of a high-desert winter night. Direct drop-in replacement parts require no fitting—just swap them in and head to the range.

• Drop-in installation — no filing, sanding, or professional fitting required. You can install this kit in minutes with basic hand tools.
• 100% manufactured in the USA — right here in Phoenix, AZ, so you’re supporting local manufacturing and getting parts built for the same climate you shoot in.
• Suppressor-friendly performance — the reduced reset and smooth break help you manage recoil and stay on target, making this kit ideal for suppressed shooting where trigger control matters most.
• Heat and dust tolerant — the drop-testing and robust design mean this kit handles the fine grit and high temperatures that Arizona shooters face.
