Genuine Glock OEM Slide Lock – Factory Fit, Factory Reliability
This part isn’t a generic copy—it’s an original Glock-manufactured slide lock with Glock’s “Universal Handguns” designation. That means it’s built to exact tolerances for consistent performance across compatible models.
Key OEM advantages:
Factory dimensions and geometry for proper fit in Glock frames
Tested by Glock to work with the company’s internal components and tolerances
Reliable engagement with the slide to help ensure secure lock-up during firing and safe takedown when needed
If you’re maintaining a defensive, competition, or duty pistol, using authentic OEM parts like SLIDE LOCK 100002687 helps keep your Glock running the way it was designed.
Wide Compatibility – Fits Most Glock Gen 1–4 Models
The Glock Slide Lock 100002687 is designed to fit Glock Gen 1–4 pistols across multiple calibers, giving it broad compatibility in one part number.

Exclusions: This part does not fit some later or specialty models, including (but not limited to) G17 Gen5, G19 Gen5, G19X, G26 Gen5, G34 Gen5 MOS, G36, G36 FGR, G42, G43, G44, G45, and G45 MOS.
Always confirm compatibility with your specific Glock model and generation before ordering or installing.
Blued Steel Construction – Durable and Low-Profile
The SLIDE LOCK 100002687 is made from hardened steel with a blued finish, giving you a part that’s both durable and discreet.
Benefits of the blued steel construction include:
Excellent wear resistance in a high-contact component
A low-glare, low-profile finish that blends with factory Glock parts
Strong, long-lasting engagement surfaces where the lock interfaces with the slide
This is a true working component, designed to handle regular maintenance cycles and thousands of rounds over the life of the pistol.
Restores Smooth Takedown and Everyday Function
A worn, damaged, or out-of-spec slide lock can make field stripping harder, feel inconsistent, or interfere with the way your slide locks into place. Replacing that part with a fresh OEM slide lock helps:
Restore smooth takedown when disassembling your Glock for cleaning
Maintain secure engagement between frame and slide during normal operation
Ensure your pistol continues to run with factory-level reliability
For shooters who practice and clean regularly, a properly functioning slide lock is more than convenience—it’s part of keeping your Glock safe, predictable, and easy to maintain.
Ideal for Maintenance, Repairs, and Custom Builds
The SLIDE LOCK 100002687 is a must-have part for:
Routine maintenance on high-mileage Glocks
Armorers and gunsmiths who service multiple pistols
Custom Glock builds where all small parts are selected individually
Owners who want a backup parts kit on hand for critical components
Because the slide lock is small and inexpensive, many shooters keep a spare ready in their range or armorer’s kit so they can quickly address wear or damage without waiting on parts orders.
Easy to Integrate into Factory or Upgraded Setups
Whether your Glock is box-stock or heavily upgraded with aftermarket slides, barrels, and trigger components, using an OEM slide lock helps ensure this critical interface remains reliable.
Plays nicely with most factory and aftermarket slide assemblies
Complements both concealed carry and competition setups
Works alongside other Glock OEM internal parts for consistent performance
Because this part maintains Glock’s original design, it’s often preferred over some non-OEM options in defensive or duty pistols where absolute reliability is a priority.
Compact, Lightweight, and Always Ready
Despite its small size and weight (only a few grams in shipping listings), the slide lock plays an outsized role in how your Glock feels and functions.
With SLIDE LOCK 100002687 you get:
A compact replacement part that’s easy to store as a spare
Minimal added weight, preserving Glock’s famously light carry profile
Confidence that this critical part is up to factory standards
