Product Description Introducing the Zaffiri Precision Integrated Blowhole System (IBS) Complete Upper Slide for the Glock 19 Gen3. Zaffiri Precision took their time-tested ZPS.1 slide design and seamlessly blended it with the Blowhole Compensator, allowing you to effectively manage propellant gases for flatter, more controlled shooting. Achieve the performance benefits of a compensated setup without requiring a threaded barrel. Machined from a single billet of 17-4 stainless steel with tight tolerances, this slide delivers enhanced accuracy and reliability. Finished in a bold Flat Dark Earth coating with a Gold TiN barrel finish, this slide is as visually striking as it is functional. Cut for an RMR footprint, it accepts any optic using the Trijicon RMR mounting standard.
