About the Sig Sauer P290RS Recoil Reduction Spring Rod by DPM Systems:
Will Fit: Sig Sauer P290RS .9mm
The DPM Mechanical Recoil Reduction System is a direct replacement for the stock recoil rod and does not change the configuration of the gun.
This system works due to the multi spring intricate rod (3 springs) and controls the functionality of the gun. The third spring which is contained within the rod controls the movement of the slide so it never rams on the frame.
Included with the system are two external springs, allowing the user to fine-tune the weapon to their personal preferences. The longer spring (with more coils) provides greater strength and a higher pound rating than the shorter spring.
**As we lead the evolution of recoil reduction technology, products may change versions (new design with different springs, with or without plugs, washers, etc.) without any prior notice.**

The DPM Sig Sauer P290RS recoil spring system works due to its multi spring rod design (three springs) by producing an advanced recoil reduction technique by gradually slowing the slide down before impacting the frame of the pistol using Spring No. 1 (see fig. below) and Spring No. 2. The third spring (Spring No. 3) which is contained within the rod itself controls the movement of the slide so it never rams on the frame.


*Dimensions of the spring are the same as the original.
