Keep your Diamondback DB9 running smoothly with this outer recoil spring, designed to absorb recoil and stabilize the cycle.

This outer recovery spring is an original part compatible with the Diamondback DB9 pistol in 9 mm caliber. It is part of the dual spring system that equips this compact model, and ensures the absorption of part of the recoil energy during firing. Positioned around the guide rod, this outer spring works in tandem with the inner spring to regulate the travel of the slide and maintain a fast, smooth closing.

  • Type : Outer recoil spring
  • Position : Around the guide rod, external part
  • Material : Treated spring steel
  • Treatment : Anti-relaxation thermal / black or stainless steel finish
  • Voltage : Calibrated according to DB9 specifications
  • Mounting : Direct with original guide rod
  • Lifespan : 3,000 to 5,000 cycles (manufacturer's recommendation)

Role of the outer spring on the DB9

The Diamondback DB9 uses a dual-spring recoil system: an inner (center) spring and a longer outer spring . The latter plays a crucial role in regulating the slide during recoil, absorbing shock and ensuring smooth closure. A weakened outer spring often results in harsh recoil, incomplete cycles, or irregular ejection.

Material and performance

Made from heat-treated spring steel , this component is designed to retain its shape and tension despite rapid and repeated bending stresses. Heat treatment prevents loss of elasticity and extends service life even under heavy use.

Replacement and compatibility

100% compatible with all generations of DB9 pistols. It is recommended to replace the outer spring at the same time as the inner spring to ensure optimal operation. Simple installation without special tools.
