✅ Why Use a Recoil Calibration Pak?

Sometimes the correct spring weight is hard to determine. Therefore, Wolff created this kit to remove the guesswork.

Here is the simple tuning process:

First, install the strongest spring.
Next, test-fire your pistol with your chosen ammo.
Then, step down one spring at a time until cycling feels smooth and controlled.

Because of this method, you avoid wasted money on the wrong springs. More importantly, you get a pistol that runs clean, flat, and reliable.
