Assembled Combat Window Slide for Glock 43/43X — Burnt Bronze RMSc

Burnt bronze cerakote combat window slide for Glock 43 and Glock 43X frames, function-tested and shipped fully assembled. The Shield RMSc footprint optic cut accepts Holosun 507K, Shield RMSc, and Sig Romeo Zero — verify your optic's mounting pattern before installing. The top window aids cooling and showcases the installed nitride barrel.

Fit and Compatibility:

• Glock 43 and Glock 43X OEM frames
• Not compatible with Glock 48 (longer slide rail length)
• 9mm Luger only

What's Pre-Installed:

• Combat window slide in burnt bronze cerakote
• Shield RMSc footprint optic cut
• Black nitride 9mm replacement barrel
• 3CR Tactical slide completion kit (extractor, striker, springs, channel liner)
• Standard height polymer sights

Break-In: Apply lubricant to the slide rails and barrel hood before the first shot. Run 200 rounds of 124-grain or heavier ammunition before stepping down to lighter loads to let the action settle and confirm reliable cycling. Torque optic mounting screws to manufacturer spec before live-fire.

Optic Mounting Hardware

• Cover plate screws: 6-32 × 1/3″
• Optic mount screws: 6-32 × 7/16″

For optic installation, use the mounting kit included with your optic (Holosun, Trijicon, Sig, Vortex, etc.) — manufacturer kits have the correct torque spec, head shape, and threadlocker matched to that optic. The dimensions above are for reference when sourcing a replacement cover plate or aftermarket hardware. A cover plate is not included with this slide.
