Glock Factory Dual Recoil Spring Assembly – Fits Glock 29 / 30 / 36
Genuine OEM Captive RSA • Improves Return-to-Battery & Felt Recoil Management
Part Number: 8063
Keep your compact big-bore Glock running like it should. The Glock Factory Dual Recoil Spring Assembly (8063) is a genuine OEM, captive recoil spring and guide rod unit designed for Glock 29 (10mm), Glock 30 (.45 ACP), and Glock 36 (.45 ACP) pistols.* If your slide isn’t returning with authority, you’re seeing erratic ejection, or your current spring has high mileage, this direct-replacement assembly restores factory timing, reliable return-to-battery, and smoother impulse—especially helpful on the heavier-recoiling 10mm and .45 ACP models.
*Always verify your exact model and generation (e.g., SF/Gen3/Gen4). Recoil spring assemblies are model- and generation-specific; this listing is for the configuration designated to fit Glock 29/30/36 as provided by the manufacturer’s part reference 8063.
Why Choose the OEM Glock Dual Recoil Spring Assembly
Factory-Correct Timing & Lockup
Dual, captive spring design delivers the preload and travel Glock engineered for consistent cycling and dependable return-to-battery.
Tuned for Big-Bore Compacts
Built to handle the sharper recoil curve of 10mm Auto and .45 ACP, helping reduce muzzle dip on return and improving shot-to-shot rhythm.
Drop-In Reliability
Captive guide-rod design makes replacement fast, clean, and tool-free—no chasing loose springs across the room.
Consistent Ejection & Feeding
A fresh RSA can help resolve nuisance issues like stovepipes, sluggish ejection, or inconsistent slide velocity caused by worn springs.
Genuine OEM Quality
Manufactured to Glock’s specifications for materials, spring rates, and longevity—no guesswork or tolerance stacking.
Key Features & Compatibility
Product: Glock Dual Recoil Spring Assembly (Captive)
Part Number: 8063
Compatibility: Glock 29 (10mm), Glock 30 (.45 ACP), Glock 36 (.45 ACP)
Construction: Captive dual-spring system on a hardened guide rod
Function: Manages slide velocity, reduces felt recoil, and ensures positive slide return
Important Fit Note: Glock recoil spring assemblies vary by generation (Gen3/Gen4) and specific frame variants (e.g., SF). Always confirm your pistol’s model, generation, and slide length against the part number before purchase. Not designed for Gen5.
Signs You Need a New RSA
Slide feels “mushy” on return or fails to close with authority
Erratic ejection or intermittent stovepipes with quality ammo
Noticeable increase in felt recoil after high round counts
RSA shows visible wear, set length loss, or damage
Installation (Quick Guide)
Unload & Verify Clear: Remove magazine and physically/visually check the chamber.
Field Strip: Remove slide from frame; take out barrel and old recoil assembly.
Install New RSA: Seat the dual recoil unit on the barrel lug with the rear leg properly indexed.
Reassemble: Install barrel and RSA into slide; mount slide to frame.
Function Check: Rack the slide several times; confirm smooth travel and positive return-to-battery. Perform a standard safe dry-fire function check.
If you are unsure about model/generation compatibility or installation, consult a qualified Glock armorer.
Maintenance Tips
Service Intervals: Replace the RSA at manufacturer-recommended intervals or sooner on high-round-count pistols and heavy loads.
Keep It Clean: Wipe carbon and debris from the slide channel and RSA during routine cleanings.
Run Light Lube: A thin film on the guide rod contact points is sufficient—avoid heavy oil that attracts grit.
Frequently Asked Questions
Q: Will this work in all G29/G30/G36 variants?
A: It is intended for Glock 29, 30, and 36 per OEM part 8063, but generations and SF variants can require different assemblies. Verify your exact pistol details before ordering.
Q: Can a worn RSA cause feeding or ejection issues?
A: Yes. A fatigued spring can alter slide velocity, leading to inconsistent ejection and failures to feed/return. Replacing the RSA often resolves these symptoms when ammo and magazines are known-good.
Q: Is this a complete captive unit?
A: Yes—the spring(s) and guide rod are integrated for quick, tool-free installation.
Q: Will this change my trigger pull?
A: No. The RSA affects slide movement, not the trigger mechanism.
Q: Do I need to replace other parts at the same time?
A: It’s smart to inspect mag springs, extractor, and striker spring during maintenance, but it’s not required for RSA replacement.
