Your Questions Answered
What ammunition does this slide run best with?
Based on our handling and customer feedback, this slide runs flawlessly with standard 115gr and 124gr FMJ ammunition. We did note one instance of a hiccup with a specific 147gr subsonic load during testing, so for optimal performance, we recommend sticking with common range ammo weights.
Is this compatible with an OEM Glock frame?
Yes. This slide is machined to Gen 3 specifications and is designed as a direct-fit component for a Glock 19 Gen 3 frame. It should also fit many aftermarket frames built to the same spec. Always confirm compatibility with your specific frame manufacturer.
What parts do I need to complete this slide?
This is a stripped slide assembly. You will need to source and install a barrel, recoil spring assembly (RSA), and sights or an optic plate to complete it. We stock these components separately if needed.
