Parts & Accessories
Choosing Glock parts
Most upgrades fall into a few buckets: parts that change how the pistol shoots, parts that change how you aim, and the small internals that keep it running. Decide what you want to improve, then match the part to your model and generation.
Slides and barrels
An aftermarket slide or barrel changes weight, sight cuts and accuracy, and is a common first step toward an optics-ready or match-grade build. Confirm the cut and generation match your frame before ordering.
Sights and optics mounts
Iron sights, night sights and optic mounting plates are the fastest way to aim faster in any light. Pick sights that suit your use, whether that is a crisp competition setup or high-visibility night sights for carry.
Magazines and small internals
Magazines, springs, pins and connectors are the consumables that keep a Glock reliable over thousands of rounds. Keeping spares on hand means a worn part never sidelines your pistol.
How Glock parts ship to you
Most parts and accessories are components, not firearms, so they ship straight to your door with tracking and need no dealer. The one exception is a serialized frame or receiver, which is legally a firearm and must ship to a licensed dealer. Delivery details are in our Shipping Policy.
Glock parts questions
Will these parts fit my Glock?
Fit is by model and generation, which every listing states. A Gen 3, Gen 4 and Gen 5 do not always share the same slides, barrels or internals, so match the part to your exact pistol.
Do Glock parts need an FFL?
No, with one exception. Slides, barrels, sights, magazines and internals ship directly to you. Only a serialized frame or receiver requires transfer through a licensed dealer.
Are these OEM or aftermarket?
Each listing states whether a part is factory Glock or an aftermarket brand, so you can choose stock reliability or an upgraded feature to taste.
