Extractor Depressor Plunger & Spring – Gen 5 – Part #100026254

Restore crisp, reliable extraction on your Gen 5 slide. The Extractor Depressor Plunger/Spring – Gen 5 (Part #100026254) is a precision replacement assembly engineered to maintain proper extractor tension, drive consistent case pull, and support dependable ejection cycle after cycle. Whether you’re refreshing a high-round-count pistol, completing a slide build, or stocking critical spares for your armorer’s bench, this Gen 5–spec plunger and coil spring help keep your gun running cleanly and confidently.

Why this Gen 5 extractor plunger/spring matters

• Consistent extractor tension: The matched plunger + coil spring apply steady pressure to the extractor so it bites the case rim and holds it through the entire rearward stroke.

• Cleaner ejection pattern: Proper extractor tension aids predictable, repeatable ejection, reducing stovepipes and weak throws that complicate diagnostics.

• Gen 5 geometry: Dimensioned for Gen 5 slides to support the revised firing pin safety, extractor design, and bearing interface typical of 5th-generation pistols.

• Precision manufacturing: Hardened steel plunger with a corrosion-resistant finish and a tempered coil spring provide long service life and stable tension over time.

• Armorer-grade spare: Small parts fail the hardest to find. Keep one labeled 100026254 in every range kit to minimize downtime.

Tip: If your ejection has drifted (e.g., cases dribbling over the slide or pelting your forehead), refresh the extractor depressor plunger/spring along with the recoil spring assembly and ensure your extractor claw is debris-free.

Ideal use cases

• Preventive maintenance on pistols used for training, carry, or competition

• Troubleshooting extraction/ejection anomalies without replacing the entire extractor

• Slide builds/rebuilds after refinishing, Cerakote®, or optics cuts

• High-round-count fleet service (range programs, agency/department upkeep)

Compatibility

• Designed for Gen 5 pattern slides in 9mm and other Gen 5 chamberings that share the same extractor plunger system.

• Always confirm your model, caliber, and extractor bearing spec before installation.

What’s included

• Extractor Depressor Plunger (Gen 5) – steel

• Extractor Plunger Coil Spring – tempered
  (Extractor bearing and extractor itself are not included.)

Installation overview (armorer best practices)

1. Make safe: Unload and visually/physically verify the chamber and magwell are empty.

2. Remove slide backplate: With the slide off the frame, depress the striker sleeve and gently control spring pressure as you slide the backplate down.

3. Extract small parts: Lift out the striker assembly, then capture and remove the extractor depressor plunger/spring from its channel.

4. Clean & inspect: Degrease the plunger channel; check the extractor claw and bearing for debris or wear.

5. Install new parts: Insert the new spring and plunger (plunger toward the extractor). Reinstall striker, compress assemblies, and slide the backplate up until it locks.

6. Function check: Verify striker block, trigger reset, extractor travel, and safe dry-fire. Live-fire confirm with your duty/defense ammo.

If you’re not familiar with slide internals, consult a certified armorer. Small parts are under spring tension—wear eye protection and control components during removal/installation.

Maintenance tips

• Replace small springs/plungers at regular round-count intervals (many armorers audit at 5k–10k rounds, depending on use and environment).

• Keep the extractor claw and plunger channel free of carbon and unburnt powder.

• Avoid heavy grease in the plunger bore—light oil or dry film lube is sufficient.

Symptoms a fresh plunger/spring can help solve

• Erratic ejection (forward, straight up, or inconsistent)

• Spent cases dropping back into the chamber area

• Intermittent stovepipes with otherwise in-spec ammo and recoil springs

• Weak extraction after slide refinishing or long intervals between cleanings

FAQs

Q: Will this fit earlier generations?
A: It’s engineered for Gen 5 slides. Earlier generations may use different plungers/bearings—match parts to your generation.

Q: Do I need a new extractor too?
A: Not always. Many ejection issues resolve with a clean extractor channel and a fresh plunger/spring. Inspect the extractor claw for chips/round-off before reusing.

Q: Lube or run dry?
A: Use minimal lube—a light film only. Excess oil can collect debris in the plunger channel.

Q: Do I need threadlocker anywhere?
A: No threadlocker is used for this assembly; ensure the backplate fully locks and passes function checks.
