The Lionheart Ported Nitride Barrel Slide Kit is a high-performance upgrade for Glock 19 Gen 1–3 pistols, built for faster follow-up shots and reliable function. It features a 4.6" stainless steel barrel with a black nitride finish for enhanced durability and corrosion resistance. The ported barrel design helps reduce muzzle rise, improving control and speed during rapid fire.
The included Viper Slide, finished in eye-catching gold Cerakote, is cut for RMR optics and comes with a pre-installed aluminum cover plate for flexibility right out of the box. A 14 lb lightweight recoil spring ensures smooth cycling, while the short sight assembly kit provides improved target acquisition. Compatible with OEM Gen 1–3 Glock frames, the Lionheart kit offers a balanced blend of competition-ready performance and everyday reliability in one complete package.
