The Apex Tactical 102173B Action Enhancement Kit is a drop-in trigger upgrade designed specifically for Glock 43, 43X, and 48 slim-frame pistols. If you carry a compact Glock daily or shoot one competitively, this kit replaces the factory trigger assembly with a carefully engineered performance alternative that keeps your gun running to factory spec while delivering a noticeably crisper, more predictable trigger press. It's a direct swap—no gunsmithing required—and every part is made in the USA at Apex's Phoenix facility.

What sets this kit apart is the combination of a smoother uptake, reduced travel, and a crisp break that lands between 4.5 and 5.0 pounds. The Type 3 trigger features distinctive chamfered corners and decorative cuts on the visible sides, giving your gun a finished look that matches the performance upgrade. The included trigger bar and performance connector work together to smooth out the factory reset and keep you faster and more accurate on successive shots. The center-mounted safety maintains factory safety standards, so you're not trading reliability for tuning.

This kit is engineered only for Gen 3, Gen 4, and Gen 5 Glock 43, 43X, and 48 frames made by Glock. It will not function in the G42 (shorter trigger bar geometry), and it is not compatible with non-Glock frames, including clones. Install it in a genuine Glock slim frame and you'll have a trigger that feels like a custom job at a fraction of the cost.
