The kit includes a threaded barrel crafted from 416R stainless steel with resilient black nitride coating for improved wear resistance and 1/2x28 thread pitch for suppressor and muzzle device compatibility. The kit comes with a black oxide thread protector and O-ring for secure barrel protection when accessories are not attached. This complete slide kit integrates precision components for reliable cycling and consistent accuracy, making it well-suited for those customizing G17 Gen 1-3 builds with durable aftermarket components that blend functionality with understated aesthetics.
This Lionheart complete slide kit includes all essential upper components engineered for reliable cycling and consistent performance. The black nitride slide finish provides enhanced surface hardness and corrosion resistance while creating a sleek, professional appearance. The threaded barrel is crafted from 416R stainless steel—a premium barrel material known for exceptional bore life and accuracy retention—and finished with matching black nitride coating for improved wear resistance. The black nitride finish on the barrel penetrates the surface of the steel rather than coating it, resulting in a finish that won't flake or peel even under hard use. The kit includes a black oxide thread protector with O-ring for secure barrel protection when suppressors or muzzle devices are not attached. All components are machined to exacting tolerances for proper barrel lockup, extractor engagement, and reliable extraction across various 9mm ammunition types.
The 416R stainless steel threaded barrel with black nitride finish delivers both durability and functionality. The black nitride coating provides superior corrosion resistance, enhanced surface hardness, and excellent wear resistance—particularly valuable for threaded barrels that may see repeated suppressor or muzzle device installation and removal. The 1/2x28 thread pitch is the industry-standard threading for 9mm suppressors and muzzle devices, ensuring compatibility with a wide range of aftermarket accessories. The matching black finish between slide and barrel creates a cohesive, professional appearance appropriate for defensive, duty, and range applications. The included black oxide thread protector with O-ring provides secure protection for the barrel threads when accessories are not installed, with the O-ring ensuring the protector stays firmly in place during shooting.
The Lionheart complete slide kit combines functional durability with understated aesthetics through matching black nitride finishes on both slide and barrel. The black-on-black configuration creates a professional, cohesive appearance while the nitride finishes deliver enhanced protection against wear, corrosion, and environmental exposure. The threaded barrel allows shooters to attach suppressors (with appropriate adapters for the Glock platform) for reduced sound signature or install compensators and other muzzle devices for recoil management. This blend of functionality and aesthetics makes the kit well-suited for gunsmiths and builders who value both reliable performance and clean, professional appearance in their G17 builds.
Follow safe handling practices and manufacturer instructions at all times. Ensure compliance with all applicable federal, state, and local laws. Verify proper headspacing and component compatibility before assembly. Confirm all internal components are correctly installed and functioning before live fire. If mounting a suppressor, use appropriate adapter/booster for the Glock platform to prevent baffle strikes. Ensure muzzle devices are properly mounted and torqued to manufacturer specifications. Remove thread protector before attaching suppressors or muzzle devices. Use appropriate eye and ear protection during all shooting activities.
