Desert Eagle Extraction Fix: Missing Spring & Stuck Ejector | Over the Gunsmith's Shoulder Ep. 34

A Desert Eagle came into the shop failing to extract and eject and the fix turned out to be two separate problems hiding behind one symptom. In this episode of Over the Gunsmith's Shoulder, Master Gunsmith Ken Brooks walks you through diagnosing and repairing extraction and ejection failures on a Desert Eagle pistol. Ken starts where every safe repair starts: clearing the magazine and chamber. Then the forensic work begins. He finds no spring tension on the extractor, bright wear marks that "don't look quite right," a chewed-up extractor pin, and a deteriorated rubbery buffer where the extractor spring should be. The spring is simply gone; someone has been inside this gun before. Rather than wait on a hard-to-source factory Desert Eagle spring, Ken digs through his spring stock and fits a replacement by trial and error, checking diameter, length, and tension, and showing why a spring enclosed on both ends is ideal. Along the way he explains extractor "moment of mass," why the hook must swing toward the cartridge so it grips the rim under recoil instead of leaving the case in the chamber. After the first reassembly the pistol still won't eject, so Ken drives out the ejector roll pin and discovers brass shavings and metal bits jamming the ejector short. He cleans it out, then relieves the ejector shoulder in the vise with a cutoff wheel, file, and sandpaper to gain more ejector throw, keeping a rounded shoulder so there's no fracture point. ✅ Safe magazine and chamber check before any work ✅ Reading wear marks to spot prior tampering ✅ Desert Eagle slide and bolt disassembly ✅ Removing the extractor pivot pin ✅ Diagnosing a missing extractor spring ✅ Fitting a replacement spring from spring stock by trial and error ✅ Why a spring enclosed on both ends is ideal ✅ Using "gunsmith glue" (grease) to hold parts during assembly ✅ Extractor moment of mass and hook geometry ✅ Clearing brass shavings and debris from the ejector channel ✅ Relieving the ejector shoulder in the vise for more throw ✅ Filing a rounded shoulder to avoid a fracture point ✅ Firing pin protrusion and safety function check This is the kind of practical, real-world gunsmithing you only learn by watching a pro do it. 🔧 Want to learn real gunsmithing from certified professionals? 👉 https://americangunsmithinginstitute....

Common Questions Answered Q: Why won't my Desert Eagle extract or eject? A: In this gun it was two issues at once — the extractor had no spring (so it couldn't grip and pull the case), and the ejector wasn't protruding far enough to kick the case clear. Ken fixed both: he fit a new extractor spring and relieved the ejector shoulder for more throw. Q: What causes no extractor spring tension? A: Here the extractor spring was missing entirely, with only a deteriorated rubbery buffer left in the channel. The chewed-up extractor pin told Ken someone had been inside the gun previously and likely removed it. Q: Can you substitute a generic spring for a factory extractor spring? A: Yes. Ken sorts through his spring stock and fits one by trial and error, judging it on diameter, length, and tension rather than exact specs. He prefers a spring enclosed on both ends because it seats cleanly without needing a captured end. Q: What is "moment of mass" on an extractor? A: It's how the extractor's material is balanced around its pivot. You want the hook to swing toward the cartridge under recoil so it grips the rim and pulls the case out — not away from it, which leaves the case in the chamber or on top of the next round. Q: How do you give an ejector more throw? A: Ken relieves the ejector's shoulder in the vise using a cutoff wheel, a file, and sandpaper so the ejector can extend further out the breech face. He keeps the shoulder rounded rather than square to avoid creating a fracture point. Q: How can you tell if a gun has been worked on before? A: Forensics. Ken points to a chewed-up pin, beat-over screw heads, fresh bright wear marks, and a missing part that should be there. Put the clues together and you can tell someone has been inside. 00:00 — Cold Open: A Feeding & Ejection Problem 00:51 — Welcome to Over the Gunsmith's Shoulder (Gene Kelly) 01:24 — The Desert Eagle: Safety Check & The Complaint 02:12 — First Clue: No Extractor Spring Tension — Disassembly 04:01 — Forensic Diagnosis: Unburned Powder & Prior Tampering 04:50 — The Missing Extractor Spring & Mystery Buffer 08:00 — Fitting a Replacement Spring from Spring Stock 12:37 — Extractor Moment of Mass Explained 16:38 — First Reassembly & Function Check: Still Won't Eject 21:19 — Pulling the Ejector: Brass Shavings & Metal Bits 26:10 — Relieving the Ejector Shoulder for More Throw 31:28 — Final Function Check & Wrap-Up
