Zaffiri Precision IBS FDE Complete Slide for G43X | Black Barrel

Zaffiri Precision IBS FDE Complete Slide for G43X | Black Barrel

The Zaffiri Precision IBS FDE Complete Slide for G43X provides a complete, performance-oriented upper built around a matched slide-and-barrel porting system. Its Integrated Blowhole System pairs a dedicated IBS slide with a Chunk Ported barrel, allowing the top port in the barrel to align precisely with the corresponding opening in the slide.

When fired, expanding gases are directed upward through the integrated port rather than straight out of the muzzle. This helps counter muzzle rise and supports quicker visual recovery of the sights during rapid follow-up shots. The entire system remains contained within the standard slide length, preserving the compact profile of the Glock 43 and G43X platform without adding a threaded barrel or external compensator.

The Flat Dark Earth Cerakote slide and Black Nitride barrel create a subdued, field-oriented appearance with strong contrast through the forward windows and top opening. The dark barrel treatment also provides added resistance to surface wear and corrosion, while the FDE slide finish offers durable protection for regular carry, training, and range use.

Machined from billet stainless steel, the IBS slide features sculpted front and rear serrations for secure manipulation from multiple positions. One window on each side reduces visual mass and exposes the matched barrel beneath, while the dedicated opening ahead of the front sight provides the necessary clearance for the Chunk Ported system.

The modified RMSc optic cut is configured for compatible slimline red dots, including the Holosun 407K and 507K, Shield RMSc, SIG RomeoZero, and similarly patterned optics. Installed blacked-out sights provide a lower one-third co-witness with many popular compact optics, and the included cover plate allows the slide to be used before a red dot is installed.
