Make sure your Glock 19 is unloaded and then safely field-strip the firearm. Then, remove the recoil spring, barrel, firing pin, and extractor assemblies before cleaning and inspecting all parts.

The Glock 45 uses a slide that is essentially the same as the Glock 19 Gen 5 slide.

With a wide variety of slide cuts and optic cuts for your slide, we offer a ported barrel option with ported slide options as well.
