Built and function-tested in our Florida shop. Starting with a Live Free Armory (Melbourne, FL) Black Cerakote RMSc-cut stripped slide blank for Glock 43 / 43X chambered in 9mm, we install the tall polymer sights and 3CR Tactical internals before each unit ships. Barrel is NOT included — bring your own 9mm Glock 43 / 43X barrel to complete the upper.

Specs

• Slide: Black Cerakote, OEM-profile with rear serrations
• Optic cut: RMSc footprint (sub-compact red dots)
• Iron sight cuts with tall polymer sights pre-installed (suppressor-height profile, lower-1/3 co-witness with most RMSc optics)
• Internals: 3CR Tactical slide completion kit installed (firing pin, extractor, channel liner, recoil rod)
• Built and shipped from Florida

Fitment

• Glock 43 (single-stack 9mm, 6-round)
• Glock 43X (10-round flush-fit 9mm)
• Drop-in install — no fitting required
• Not compatible with Glock 48 (longer slide profile)

Optic Compatibility — RMSc Footprint

• Holosun 507K
• Shield RMSc
• Sig Romeo Zero
• Trijicon RMRcc
• Vortex Defender CCW

Tall pre-installed sights provide lower-1/3 co-witness with most RMSc-pattern red dots.

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. Hardware is not included with this slide.

What's Included

• Assembled slide with internals (firing pin, extractor, channel liner)
• Tall polymer iron sights (front + rear, pre-installed)
• Recoil spring assembly

What You'll Need

• 9mm Glock 43 / 43X barrel — required, sold separately
• Glock 43 / 43X frame
• RMSc-footprint optic (optional)
• Lube / firearm-safe oil for break-in

Each slide requires a brief break-in period. Apply lube to wear surfaces before first range session.
