Glock Gen5 G19 / G19X / G45 / G47 Dual Recoil Spring Assembly - 39310 - UPC 764503037887
Product Description
The Glock Gen5 Dual Recoil Spring Assembly (39310) is an official factory OEM replacement component designed specifically for Glock's Gen5 compact and full-size 9mm pistol platforms—including the G19 Gen5, G19X, G45, and G47. Engineered to exact factory specifications, this dual-spring guide rod assembly regulates slide velocity, mitigates felt recoil impulse, and guarantees reliable cycling across all factory 9x19mm ammunition loadings.
Featuring a high-tensile steel inner guide rod surrounded by dual nested spring coils and a durable polymer housing end cap, the 39310 recoil assembly slows down slide travel dynamics during extraction and counter-recoil. Replacing high-round-count or worn recoil assemblies with genuine factory OEM units prevents frame battering, eliminates failure-to-feed (FTF) malfunctions, and restores crisp, factory-original lockup and timing.
Drop-in ready with zero gunsmithing required, this assembly is stamped with factory identifier "1-7" on the face. Whether performing routine scheduled armorer maintenance after 5,000+ rounds or restoring stock reliability to your primary carry sidearm, the Glock 39310 Recoil Spring Assembly delivers uncompromising durability and performance.
*Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix: Direct factory fit for Glock G19 Gen5, G19X, G45, and G47 9mm models. Note: Designed specifically for Gen5 recoil channel dimensions; NOT compatible with Gen1, Gen2, Gen3, or Gen4 Glock models.
- Ensure the firearm is completely clear, safe, and unloaded before field stripping.
- Remove the slide assembly from the frame and compress the recoil spring assembly slightly forward to clear the barrel crescent lug.
- Seat the round polymer base of the new 39310 assembly cleanly into the lower step notch of the barrel lug, ensuring centered alignment before reassembling the slide onto the frame.
