Is this a complete kit for a bare slide?
Yes, this Upper Parts Kit includes every internal component needed to assemble a completely functional Glock 17 Gen 3 slide. You will need a stripped slide, barrel, and slide completion tool (or channel liner tool) for installation. The kit does not include the slide or barrel itself.
Will this kit work on a Polymer80 or other 80% frame?
Absolutely. This UPK is designed to work with any Gen 3 Glock 17 pattern slide, which includes slides intended for use on Polymer80, Lone Wolf, and other compatible aftermarket frames. Ensure your frame is designed for a Gen 3 G17 slide for proper function.
Are the parts OEM Glock or aftermarket?
This kit is assembled with high-quality aftermarket components manufactured to meet or exceed original Glock specifications for dimensions, metallurgy, and performance. They are designed for reliable drop-in function and long-term durability, providing an excellent value compared to sourcing individual OEM parts.
What tools are required for installation?
Installing this UPK requires some basic gunsmithing tools. A slide completion tool or a dedicated channel liner installation tool is crucial for safely installing the polymer channel liner. A set of pin punches, a small hammer, and a flat surface are also recommended for assembling the other components without damage.
