Icarus Precision Omega Slide for G43 43X 21121 BLK Complete
Product Description
The Icarus Precision® Omega Complete Slide for the GLOCK® G43 and G43X in Black (SKU: 21121-BLK-Complete) is an elite, American-machined carry upgrade engineered to redefine recoil management and mechanical precision on slimline 9mm concealed carry handguns. Designed to provide competition-grade flat-shooting dynamics within a duty-ready concealment footprint, the Omega slide incorporates an advanced forward expansion port chamber that redirects expanding combustion gasses upward, significantly dampening muzzle flip and accelerating follow-up shot split times without requiring a clumsy, threaded muzzle compensator.
Precision CNC-machined in the United States from premium, heat-treated 17-4 PH billet stainless steel, the Omega slide delivers structural endurance, tight slide-to-frame tolerances, and long-term wear resistance. The exterior is treated with a battle-proven matte black protective finish that resists sweat corrosion, severe holster friction, and harsh bore cleaning solvents. Aggressive, deep-milled forward and rear cocking serrations—complemented by beveled tactile slide cuts—provide a secure purchase for one-handed press checks, emergency rack manipulations, and clearing malfunctions under extreme weather or high-stress conditions.
Shipping completely assembled and range-ready, the 21121-BLK-Complete package includes a match-grade 9x19mm barrel optimized for the Omega port architecture, a full internal slide completion kit with a hardened striker and extractor, and a factory-tuned captured recoil spring assembly. The optic pocket is precision CNC-milled to the industry-standard Shield RMSc / Holosun K footprint, allowing micro red dot sights (such as the Holosun 407K, 507K, and EPS Carry) to sit directly on the slide floor. This low-profile direct-mount configuration provides a natural point of aim and co-witness capability with standard-height combat iron sights.
*Armorer Bench Notes & Real-World Staging Guidance:*
Fitment Matrix: Direct drop-in fitment for factory GLOCK G43, G43X, G43X MOS, and G48 lower receiver frames. Also fully compatible with aftermarket slimline frames (SCT Manufacturing SCT43, Polymer80 PF9SS, Palmetto State Armory Micro Dagger). Optic Footprint: Cut for Shield RMSc / Holosun 407K/507K/EPS Carry footprints. Optic mounting screws should be torqued to 12–15 in-lbs using medium-strength blue threadlocker. Never use excessive screw length on the right-side optic screw to avoid impinging upon the extractor depressor plunger channel.
- Ensure the host firearm is completely clear, magazine removed, and chamber visually and physically verified empty.
- Field strip the legacy slide from the host GLOCK frame by pulling down the takedown levers and depressing the trigger while sliding the upper off the frame rails.
- Apply a high-grade synthetic gun lubricant to the interior frame rail slots, barrel hood, locking lug, and disconnect ramp of the Icarus Precision Omega slide.
- If mounting an optic, install the sight directly onto the machined RMSc pocket using the appropriate length M3 or 4-40 screws, torquing evenly to 12–15 in-lbs with blue threadlocker.
- Slide the complete Omega assembly onto the host frame until the slide lock engages, and conduct a manual dry-fire function check verifying trigger reset, firing pin safety plunger depression, and slide-lock hold-open on an empty magazine prior to live-fire staging.
Key Features
- Integrated Ported Expansion Chamber: Vents combustion gasses upward to substantially reduce muzzle flip without an external threaded compensator.
- 100% Pre-Assembled "Complete" Setup: Includes match barrel, full internal parts kit, striker assembly, and captured recoil spring guide rod.
- Precision 17-4 PH Stainless Steel: CNC-machined from solid billet aerospace-grade stainless steel for maximum tensile yield strength.
- Direct-Mount Shield RMSc / Holosun K Cut: Mounts popular micro red dots directly to the slide floor for ultra-low co-witness sightlines.
- Aggressive Omega Serrations: Deeply machined front, rear, and top serrations guarantee positive weapon manipulation in wet or muddy environments.
- Duty-Grade Protective Black Finish: High-hardness surface coating provides extreme resistance to holster wear, scratches, and salt corrosion.
