What Is a Glock 43 Slide?

A Glock 43 slide houses the firing pin assembly, extractor, and sights, and it works with the barrel and recoil spring to cycle the pistol. Because the Glock 43 is designed for concealed carry, its slide is lightweight, slim, and easy to manipulate—making quality and fit especially important.

Buyers often choose between:

• OEM factory slides

• Complete replacement slides

• Custom and optic-ready slides

Each option serves a different purpose depending on use and budget.
