DPM System, Walther PDP

Recoil-damping locking spring from DPM for Walther PDP

This DPM recoil spring is designed to use 3 specially designed springs for damping.

The third spring, integrated in the spring guide rod, creates additional counterpressure shortly before the bolt hits/in the locking block, which slows the bolt down.

This is clearly noticeable after installation, even when empty and manually reloading the pistol.

The DPM system offers the following advantages:

• Increase in the service life of the weapon or reduce wear due to lower load
• Reduction of recoil
• General improvement of repetition behavior and thus avoidance of feeding problems
• Better control of the pistol and thus faster firing sequences
• When using a red dot sight, the service life is increased as it is also subjected to less stress
