Assembled Glock 43 / 43X Compensated RMSc Slide — Nitride Barrel

Drop-in compensated slide assembly for Glock 43 and Glock 43X frames. The integrated top-port compensator redirects exhaust gas upward to flatten muzzle rise and reduce felt recoil — meaningful gains on a subcompact 9mm where every bit of control matters. Ships built and function-tested in our Florida shop, ready to mount on your frame.

Frame Compatibility

Fits OEM Glock 43 and Glock 43X frames. Verify clearance with aftermarket frames before ordering.

Finish

Black cerakote slide body with a black nitride 9mm crown-cut barrel.

Features

• LFA Pro Comp Combat slide profile with integral top-port compensator
• RMSc optic footprint — fits Shield RMSc, Holosun 407K / 507K, and similar micro red dots
• Tall co-witness polymer sights, usable with or without an optic
• Full-length 9mm crown-cut barrel, black nitride finish
• Slide internals and recoil assembly pre-installed
• Recommend an optic-manufacturer screw kit over generic 6-32 hardware for proper torque spec

Break-In Note

Run 124gr or heavier 9mm during the first 200-round break-in window. Lighter 115gr loads may not fully cycle until the comp and recoil system seat in. After break-in, use whatever load groups best.
