Spring-Loaded Bearing (LCI) for Glock® — Extractor/LCI Detent
SKU: 100002724
Restore crisp extraction and a positive Loaded Chamber Indicator (LCI) with the Spring-Loaded Bearing (LCI) for Glock® (100002724). This tiny but critical detent lives inside the extractor depressor plunger assembly, working with the extractor spring to set proper extractor tension and to actuate the LCI extractor tab. The result: reliable case control, more consistent ejection, and a clear tactile/visual LCI cue when a round is chambered.
Whether you’re refreshing a high-mileage slide, troubleshooting erratic ejection, or completing a build to LCI-spec, this bearing is a low-cost upgrade that pays reliability dividends.
Why Choose the LCI Spring-Loaded Bearing
Restores Positive Extractor Tension
Worn or deformed bearings can cause sluggish extraction or weak ejection. A fresh LCI-profile bearing helps return your Glock® to factory-style timing.
Supports the Loaded Chamber Indicator
Designed for LCI extractors, this bearing interfaces with the extractor/spring stack so the extractor’s LCI shelf can signal a chambered round (where equipped), aiding both tactile and visual checks.
Cleaner, More Predictable Ejection
Proper spring preload and alignment help reduce brass-to-face and erratic patterns—especially noticeable on high-round-count training guns.
Drop-In Small Part, Big Impact
Quick to install during a slide service and inexpensive to keep on hand in any armorer kit.
Key Features at a Glance
Part Type: Spring-Loaded Bearing (LCI style) for Glock®
SKU: 100002724
Function: Sets extractor spring preload and supports LCI extractor actuation within the extractor depressor plunger assembly
Construction: Precision-formed bearing with smooth exterior for consistent movement
Use Cases: Preventive maintenance, reliability refresh, slide builds to LCI spec
Compatibility Note: Glock® uses caliber- and generation-specific spring-loaded bearings (LCI vs. non-LCI). This part is the LCI variant. Always verify your pistol’s model, caliber, generation, and extractor style (LCI or non-LCI) before purchase. Mixing non-matching bearings and extractors can impair function.
Signs You Need an LCI Bearing Refresh
Erratic ejection or weak extraction after high round counts
Mushy feel in the extractor system during diagnostics
LCI tab fails to present clearly with a chambered round
Recent parts swaps with mixed-source components
High-Level Installation Overview
Unload & Clear: Remove magazine; visually & physically verify an empty chamber.
Strip the Slide: Remove the slide from the frame per the manual.
Disassemble Plunger Assembly: Capture the extractor depressor plunger spring, then withdraw the original spring-loaded bearing.
Install New LCI Bearing: Assemble with the correct orientation into the plunger/spring stack designed for LCI extractors.
Reassemble & Check: Reinstall extractor and striker components, then do a function check (extractor tension, dry cycling, and LCI presentation) before live fire.
If you’re new to Glock® slide internals—or working across generations—have a qualified armorer verify orientation and compatibility.
Maintenance Tips
Keep Channels Clean: Carbon and grit in the extractor channel/plunger tunnel can hinder movement. Clean during every deep service.
Use Minimal Lube: Heavy oil in striker/extractor channels attracts debris. Run these areas almost dry.
Replace Related Wear Parts: Consider a new extractor spring when you replace the bearing; inspect the extractor claw and plunger head for wear.
Frequently Asked Questions
Q: What’s the difference between LCI and non-LCI bearings?
A: The LCI bearing is profiled to work with LCI-style extractors that provide a tactile/visual chamber indicator. Non-LCI bearings are shaped differently and should not be mixed with LCI extractors.
Q: Will this fit all Glock® models?
A: Not universally. Bearings vary by caliber and generation. Confirm your exact pistol (e.g., 9mm, .40, .45 GAP, etc.) and LCI extractor usage before ordering.
Q: Can this fix brass-to-face?
A: Often it helps by restoring correct extractor tension. Also inspect extractor, ejector, and recoil spring for a complete solution.
Q: Do I need special tools?
A: A bench block and Glock-size punch make the job easier. Eye protection is recommended—spring tension is involved.
Q: Will it change trigger feel?
A: No. This part influences extraction/ejection and LCI function, not the trigger system.
