Glock Internal Parts

This section covers the small internal components that keep a Glock pistol running, from firing pin springs and locking blocks to the trigger connector and slide stop lever. Combat Armory stocks 90 parts across these subcategories, priced from $1 to $49.99, including higher-volume lines like the 63 thread protectors and complete lower and upper parts kits.

Typical parts include the Combat Armory Trigger Housing With Ejector For Glock, the Extended Magazine Release for Gen 1-3 Glocks, and the Magazine Release Catch Spring For Glock. Most small parts, such as springs, pins and detents, are sold individually so you only need to replace what actually wore out or broke on your pistol.

Confirm your Glock generation before ordering, since some internals such as the magazine release and trigger housing differ between Gen 1-3 and Gen 4-5 frames, and an incorrect part will not seat or function correctly once installed on your pistol.
