Made to fit Gen4 Glocks and interchangeable for Right and Left hand shooters.

This is an excellent item that will make it easier and faster to perform magazine reloads. Because the push button is larger, you don't have to alter or change your grip to depress the Magazine Release button! That means you'll be faster changing the magazines and, also, you'll be faster and more accurate for the next shot!

Machined from durable anodized aluminum, easily installed in minutes!

You can engage this snag free Extended Aluminum Mag Catch without breaking or changing your grip. And, it feels a lot better on your thumb! Highly recommended for all shooters. Will not interfere with concealment or duty holsters.
