George Tahanian, member, from CA, United States, asked on September 07, 2021

What is the difference between the short, middle , and long spring? Mine just came in and I can’t figure out why there’s 3 kinds of springs

Expert Answer
A
Answered by Hunter, Gear Expert, from OH, United States, on January 25, 2022

The DPM Recoil Rod Reducer System for Glock has a different springs for the user to determine which spring works best for them. "This system works due to the multi spring intricate rod (three 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. Also accompanying this system are two separate springs so the shooter can fine-tune the weapon for his/her personal standards. The longer spring (more coils) is stronger and has a heavier pound rating than the shorter spring."

What are the lbs ratings on the springs? I have a Glock 23 and want to use which ever spring is closer to 17-18lbs standard spring that comes with gun

Expert Answer

Answered by Ryan Tarczynski, Gear Expert, from IL, United States, on December 17, 2020

Unfortunately, the manufacturer does not provide poundage or tension specifications for any of the DPM units on their website and that you would need to contact DPM directly to see if they can provide those values.
