Product Description The Shadow Systems 5" Threaded Spiral Fluted Barrel in Bronze is a match-grade upgrade engineered for shooters who demand both precision and reliability. Designed to fit the Shadow Systems DR920, MR920L, and Gen 5 Glock G17, this barrel features carefully refined geometry that promotes more consistent lockup without compromising function. The fully supported chamber is rated for hot +P ammunition as well as lead bullets, offering broad compatibility with mainstream commercially available 9mm loads.
