Glock 34 Slides, Barrels, Magwells & Upgrades
Shop Glock 34 slides, barrels, magwells, compensators, sights, triggers, and upper components from NineX19. This collection includes G34 parts for Gen 1–4 and Gen 5 pistols, with options for competition builds, optic-ready uppers, barrel replacements, and grip enhancements.
G34 Slides
Build an optic-ready Gen 3 upper with the NineX19 X1 RMR-cut Glock 34 slide. The X1 features our signature windowed design, aggressive rear serrations, and an RMR-pattern optic cut for compatible red-dot sights.
The current X1 slide is designed for Glock 34 Gen 3 configurations. Confirm the required recoil-spring assembly, internal components, and optic-mounting hardware before completing your upper.
Glock 34 Barrel Options
Browse Glock 34 barrels for Gen 1–4 and Gen 5 pistols. NineX19 Match V2 and Revolution barrels are precision machined and available in multiple finishes for factory-slide replacements and custom G34 builds.
Gen 1–4 and Gen 5 barrels are different configurations. Select the barrel specifically listed for your pistol generation rather than assuming that every G34 barrel is interchangeable.
G34 Magwells
The NineX19 Hybrid Magwell for Glock 17/34/45/47 gives compatible factory G34 frames a larger, more forgiving reload funnel without the excessive bulk of a dedicated race-gun magwell. Machined from 7075 billet aluminum, it improves magazine indexing and helps create a more consistent grip position.
Compensators, Sights and Other Parts
Additional Glock 34 upgrades include compatible compensators, tritium sights, triggers, slide back plates, and upper components. Compatibility varies by generation: the NineX19 Gen 1–4 trigger does not fit Gen 5 pistols, while the Herrington Arms HC95 compensator is intended for compatible Gen 5 configurations.
Generation Compatibility
G34 slides, barrels, recoil-spring assemblies, triggers, magwells, and certain internal components are not universally interchangeable across generations. Review the generation and installation requirements on each product page before ordering or assembling your pistol.
