Apex Connector for Slim Frame Glock Pistols

What It Is

This is a drop-in trigger connector for slim-frame Glock pistols, designed to reduce trigger pull weight to approximately 4.5 lbs when paired with a factory trigger bar or the compatible aftermarket trigger bar. It replaces the factory stamped connector to provide a cleaner break and lighter pull without modifying the trigger housing or sear engagement. Progressive stamped from heat-treated spring steel and finished with a Nickel-Teflon coating for corrosion resistance and smooth engagement.

Install Difficulty

Level: 2 out of 5

FAQ

Will this work in my G43X MOS?

Yes. The connector is compatible with all slim-frame Glock models including the 43X MOS and 48 MOS. The MOS slide adds no changes to trigger housing geometry.

Do I need to replace the trigger bar too?

No. The connector drops into the factory trigger bar assembly. For a further reduction in take-up and overtravel, you can pair it with the aftermarket trigger bar designed for slim frames, but it is not required.

Does this affect the trigger safety?

No. The connector geometry is designed to maintain proper engagement of the trigger safety blade and drop-safety plunger. The 4.5 lb pull figure assumes all other parts are factory spec.
