Frequently Asked Questions

What are the main differences between the GS Fast Trigger carry and competition versions?

The carry version typically includes a factory minus connector (around 4.5-5 lbs) and a 4.5 lb striker spring, aiming for a 4-4.5 lb pull. The competition version features a 3.5 lb connector and lighter striker springs (4 lb and 4.5 lb), targeting a pull weight of 3-3.5 lbs for faster shooting.

What is the benefit of the NP3 coating on the GS Fast Trigger's trigger bar?

The NP3 coating provides self-lubricating properties and a very low coefficient of friction, reportedly lower than gold titanium nitride. This enhances the smoothness of the trigger bar's movement within the firearm, contributing to a better trigger feel.

How does the adjustable trigger stop on the GS Fast Trigger work?

The trigger stop is an adjustable set screw located in the rear of the trigger housing. It limits the rearward travel of the trigger bar after the striker is released, reducing over-travel and allowing for quicker manipulation and potentially faster follow-up shots.

What are the advantages of the steel trigger housing pin included in the GS Fast Trigger kits?

Factory Glock Gen 5 firearms often use a plastic trigger housing pin. The included steel pin is more robust and is anodized black, preventing it from bending over time, which can occur with the plastic version and potentially affect trigger movement consistency.
