Glock 47739 9Mm Fits 19 Gen4 Black Steel
The Glock 47739 is a factory replacement barrel engineered for the Glock 19 Gen4 pistol. If you're maintaining your Gen4 or looking to refresh a worn barrel with Glock's own precision manufacturing, this steel barrel delivers the same reliability you expect from the factory. Glock barrels are cut to exacting tolerances and built to handle thousands of rounds without compromise—whether you're training at the range, carrying for duty, or shooting competition.
This is genuine OEM hardware, not an aftermarket alternative. That means it's designed to function seamlessly with your Gen4's existing components and maintains the same performance envelope Glock pistols are known for. Replacement barrels are a smart maintenance item for high-round-count shooters or a way to extend the life of a well-used firearm.
Black steel construction is standard Glock issue—durable, corrosion-resistant with proper care, and built to last. Whether you're doing routine maintenance or planning ahead, having a quality factory barrel on hand makes sense.
