Description
The factory Glock trigger gets the job done, but most folks who put rounds downrange want a little more from it. The Apex Polymer Action Enhancement Kit is one of the most popular ways to fix that. It's a full drop-in package that replaces the factory polymer trigger, connector, and safety plunger with matched Apex components, so you get a noticeably better feel without any permanent changes to your pistol.
The kit bundles the Apex Polymer Action Enhancement Trigger with a Gen 3 trigger bar, the Apex Ultimate Safety Plunger, and the Apex Performance Connector. Together those parts smooth out the uptake and reset, trim down pre-travel and overall travel, and give you a crisper break. You're also looking at roughly a one pound reduction in pull weight compared to stock, which is enough to feel the difference right away but not so light that it changes how the gun carries. The center-mounted pivoting safety keeps the factory safety values intact, so the trigger stays safe to run day in and day out.
What the Apex Action Enhancement Kit Fits
This one is built for standard-frame Gen 3 and Gen 4 Glocks: the G17, 17L, 19, 22, 23, 24, 26, 27, 31, 32, 33, 34, and 35. It's not made for Gen 5 pistols, and it won't work in the 10mm, .45 ACP, or .45 GAP models. If you've got a common 9mm or .40 Glock from the Gen 3 or Gen 4 era, you're in good shape.
Installing the Apex Polymer Trigger Kit
All three parts are true drop-in replacements, so no fitting or gunsmithing is required. Anyone comfortable with a basic Glock takedown and a punch can knock it out in a sitting, and plenty of owners report it's a straightforward job. If you're not comfortable working on your own gun, a gunsmith or armorer can handle it quickly. Worth noting: the trigger bar finish can arrive in either matte nickel or bright nickel, so don't be surprised if the shade varies from photos.

Frequently Asked Questions
Will this Apex trigger kit fit my Glock 19 Gen 4?
Yes, the kit is made for standard-frame Gen 3 and Gen 4 Glocks, and the G19 is right in that lineup. It also covers the G17, 17L, 22, 23, 24, 26, 27, 31, 32, 33, 34, and 35. Just make sure your pistol is a Gen 3 or Gen 4 and not a Gen 5.
Does the Apex Action Enhancement Kit work in Gen 5 Glocks?
No, this kit is designed for Gen 3 and Gen 4 pistols only and will not work in Gen 5 models. It also does not fit the 10mm, .45 ACP, or .45 GAP Glocks. If you're running one of those, you'll want a different Apex option.
Is this kit hard to install?
Not particularly. All three parts are direct drop-in replacements with no fitting or gunsmithing required, so if you're comfortable field-stripping your Glock and using a punch, you can handle it. If you'd rather not do it yourself, any gunsmith or armorer can install it in a few minutes.
How much does the Apex kit change the trigger pull?
You'll see roughly a one pound drop in pull weight versus the factory setup, along with reduced pre-travel, shorter overall travel, and a shorter reset. The break comes out crisper and the uptake feels smoother. The center-mounted pivoting safety keeps the factory safety values in place.
