Build-Your-Own Windowed / Ported Slide Kit for Glock 19

Build your own windowed ported slide kit Glock 19 and get the exact compensated, weight-reduced upper you’ve always wanted.

First, you select the window layout — side windows only, top window, or full hybrid. Then you choose porting — dual top ports, side ports, or barrel-only. After that, pick your optic cut (RMR, 507C, DPP, ACRO, RMSc, or multi). Next, decide on Cerakote — over 30 colors or raw/DLC finishes.

You also customize the barrel — ported, threaded, TiN gold, fluted, or color-matched. Finally, select sights — suppressor-height steel, night sights, fiber optic, or none. We install every internal part, the correct recoil assembly, and live-fire test your exact build-your-own windowed ported slide Glock 19 before shipping.

Because you control every detail, your finished upper drops straight onto any Gen 3 or Gen 5 Glock 19 (or P80) and runs perfectly from round one.

What you customize:

• Window style & placement
• Port pattern & location
• Optic cut (or none)
• Cerakote or specialty finish
• Barrel type & coating
• Sight height & style
• Full assembly + live-fire test
