Glock 40 S&W Gen 4 Trigger Housing w/ Ejector Review

Let’s Talk About Glock 40 S&W Gen 4 Trigger Housing w/ Ejector

The Glock 40 S&W Gen 4 Trigger Housing w/ Ejector – it’s a seemingly small part, but crucial for the reliable function of one of the most popular handgun platforms in the world. Glock pistols are renowned for their simplicity, durability, and, above all, reliability, which hinges on components like this trigger housing functioning flawlessly. I’ve spent years customizing and maintaining various firearms, and I’ve learned that even the smallest part can make or break the performance of a weapon.

A friend of mine was experiencing erratic ejection issues with his Glock 22 Gen 4. The empty casings were hitting him in the face, a sure sign of an ejector problem. Rather than sending the whole pistol back to Glock, he asked if I could take a look.

Upon inspection, I discovered a hairline crack in his trigger housing, right where the ejector is seated. This explained the inconsistent ejection. So, a replacement Glock 40 S&W Gen 4 Trigger Housing w/ Ejector became a necessity.

My first impression of the replacement part was positive. It looked identical to the original, a testament to Glock’s commitment to consistent manufacturing. Other aftermarket options exist, some with “enhanced” ejectors, but for this repair, I wanted to stick with the OEM part for guaranteed compatibility and reliability. No disappointment here, just a feeling of confidence that this would solve the problem.
