Glock 17 Gen 3 Slides, Barrels, Magwells & Upgrades
Shop Glock 17 Gen 3 slides, barrels, magwells, sights, triggers, and upper components from NineX19. This collection includes individual G17 Gen 3 parts and coordinated slide-and-barrel combinations for competition, range, carry, and custom pistol builds.
G17 Gen 3 Slides and Ported Combinations
Choose the NineX19 X1 for an optic-ready slide featuring our signature windowed design, aggressive rear serrations, and an RMR-pattern optic cut. For an integrated ported upper, the Vapor combines a ported slide and matching barrel engineered to work together as a coordinated system.
G17 Gen 3 Barrel Options
Browse Glock 17 barrels in standard and threaded Match V2 and Revolution configurations. These Gen 1–4 barrel options are available in multiple finishes for factory-slide replacements, compensator-ready builds, and customized pistols.
Select the required finish and threaded or non-threaded configuration on the individual product page. A threaded barrel is required when installing a compatible thread-on compensator.
Glock 17 Gen 3 Magwells
The NineX19 Magwell for Glock 17/34/45 provides a larger, more forgiving magazine opening while maintaining a practical profile. Machined from 7075 billet aluminum, it improves magazine indexing and helps support a consistent grip during reloads.
Triggers, Sights and Upper Components
Additional upgrades include the NineX19 Gen 1–4 trigger, blackout tritium sights, slide back plates, and other upper components. Review each product page to confirm fitment and determine whether additional parts are required for installation.
Generation Compatibility
Gen 3 slides use generation-specific recoil-spring and slide-component specifications. Slides and certain internal components are not universally interchangeable across Glock generations. Confirm that each slide, recoil-spring assembly, trigger, magwell, and internal component is compatible with your Gen 3 pistol before ordering.
