About this product
Polymer Action Enhancement Kit for Glock® – Gen 3/4 by Apex Tactical. Fits Glock.
Ships to all 50 states. Available nationwide.
The Apex Polymer Action Enhancement Kit for Glock® Gen 3 and Gen 4 pistols delivers a refined trigger feel with a noticeable reduction in pull weight and travel distance. This drop-in kit combines three precision components: the Apex Polymer Action Enhancement Trigger with a Gen 3 trigger bar, the Apex Ultimate Safety Plunger, and the Apex Performance Connector. Together, they provide a practical upgrade for shooters who want a smoother, more consistent trigger without the need for complex gunsmithing.
Key performance improvements:
- Reduces trigger pull weight by approximately 1 lb. from factory specifications
- Shortens pre-travel, overall travel, and reset distance for faster follow-up shots
- Smoother uptake and reset with a crisp, clean break
- Center-mounted pivoting safety maintains factory safety values and reliability
- Direct drop-in replacement parts — no fitting or permanent modifications required
- Trigger bar finish may vary (Matte Nickel or Bright Nickel finish)
Real benefits for California gun owners: This kit is designed specifically for Glock® Gen 3 and Gen 4 models, which are common on the California Roster. The drop-in installation means you can upgrade your trigger without altering the pistol’s internal safety mechanisms. The reduced pull weight and shorter reset make it easier to maintain accuracy during range sessions or defensive practice, while the factory-tested safety plunger ensures consistent operation under live-fire conditions.
Fitment notes: Compatible with all Glock® Gen 3 and Gen 4 pistols in 9mm, .40 S&W, .357 SIG, .45 ACP, and .380 ACP (including models G17, G19, G22, G23, G26, G27, G31, G32, G33, G34, G35, G36, G37, G38, G39, G42). Does not fit Gen 5 models. The kit uses a Gen 3 trigger bar, so it works as a direct replacement in Gen 3 frames and also fits Gen 4 frames with the included trigger housing pin. No additional adapters or spacers required.
