This DTT Stiffler Manufacturing Lionheart complete slide kit delivers enhanced recoil management for Glock 17 Gen 1-3 platforms. The slide features a black nitride finish providing resistance to wear and corrosion while maintaining a sleek aesthetic. The kit includes a ported barrel crafted from durable 17-4 stainless steel, designed to improve muzzle rise control during rapid fire. The slide parts kit includes a 13 lb reduced recoil spring, optimizing slide cycling for a more manageable shooting experience. This complete slide kit integrates precision components for reliable cycling and improved control, making it well-suited for those customizing G17 Gen 1-3 builds with performance-focused components that combine functionality with robust design.
This Lionheart complete slide kit includes all essential upper components engineered for enhanced recoil management and reliable cycling. The black nitride slide finish provides resistance to wear and corrosion while creating a sleek, professional appearance. The ported barrel is crafted from 17-4 stainless steel—a high-strength material known for exceptional durability—and features barrel ports that vent propellant gases upward to counteract muzzle rise. This design helps keep the muzzle flatter during firing, enabling faster sight realignment and quicker follow-up shots in rapid-fire scenarios. All components are machined to exacting tolerances for proper barrel lockup, extractor engagement, and reliable extraction across various 9mm ammunition types.
The 17-4 stainless steel ported barrel is the centerpiece of this kit's recoil management system. The barrel ports allow propellant gases to escape upward as the bullet exits, creating downward pressure that counteracts the natural tendency of the muzzle to rise under recoil. This reduction in muzzle rise helps shooters maintain sight picture through the firing cycle and acquire the next target more quickly—particularly valuable in competition shooting, rapid-fire drills, and dynamic shooting scenarios where speed matters. The 17-4 stainless steel construction provides superior strength and corrosion resistance while maintaining dimensional stability even under sustained fire. The ported design works synergistically with the included reduced recoil spring to create a balanced recoil management system.
The included 13 lb reduced recoil spring optimizes slide cycling for use with the ported barrel configuration. The reduced spring weight complements the ported barrel's gas venting by allowing the slide to cycle smoothly with the reduced pressure from vented gases. This balanced system maintains reliable cycling while contributing to the overall reduction in felt recoil and muzzle rise. The reduced recoil spring helps ensure consistent ejection and feeding while working in harmony with the ported barrel to create a more manageable shooting experience—particularly beneficial during extended shooting sessions or when transitioning between multiple targets quickly in competition or training environments.
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. Ported barrels may increase noise and muzzle blast; use appropriate hearing protection. Test function with your chosen ammunition to ensure reliable cycling with reduced recoil spring. Use appropriate eye and ear protection during all shooting activities.
