This guide details the installation of the Glock Performance Trigger into a .40 S&W Gen 5 Glock pistol. A critical step involves swapping the ejector from a 9mm to a .40 S&W variant to ensure proper function. The process includes detailed disassembly and reassembly of the Glock frame, highlighting the differences in ejectors and the importance of correct installation for achieving a lighter trigger pull.

Quick Summary

To install the Glock Performance Trigger in a .40 S&W Gen 5 Glock, you must swap the 9mm ejector for a straight .40 S&W ejector. This is crucial because the 9mm ejector's curve can interfere with the larger .40 caliber casing, potentially causing dangerous malfunctions.

Frequently Asked Questions

Can the Glock Performance Trigger be installed in a .40 S&W Gen 5 Glock?

Yes, but it requires a critical modification. The standard Glock Performance Trigger is designed for 9mm. For .40 S&W Gen 5 Glocks, you must swap the 9mm ejector for a .40 S&W ejector to ensure proper function and safety.

What is the main difference between a 9mm and a .40 S&W Glock ejector?

The primary difference is their shape. The 9mm ejector has a curve or bend to reach the smaller casing, while the .40 S&W ejector is straight because the larger casing diameter requires a different angle of engagement for reliable ejection.

How do you disassemble the frame of a Gen 5 Glock for trigger work?

First, ensure the firearm is unloaded. Pull the slide back slightly, then pull down on both sides of the slide lock lever to release it. Remove the slide, then drive out the trigger pin and the plastic trigger housing pin. Remove the locking block and slide stop.

What is the typical trigger pull weight of a stock Gen 5 Glock?

A stock Gen 5 Glock typically has a trigger pull weight ranging between 5 to 5.5 pounds straight out of the box. The enhanced performance trigger aims to reduce this significantly, often to around 3 to 3.5 pounds.

What are the benefits of installing a lighter trigger pull on a Glock?

A lighter trigger pull requires less force to activate, which helps minimize unintentional movement of the firearm during the shot. This leads to a more stable sight picture and can improve overall shooting accuracy, especially during rapid fire.
