✅ Why Use a Recoil Calibration Pak?

Sometimes, the correct spring weight is not obvious. Therefore, Wolff designed this kit to let you test and tune with confidence.

Here’s how it works:

First, start with the strongest spring.
Next, test your pistol with your chosen ammo.
Then, step down in weight until you get smooth cycling, solid lockup, and reliable feeding.

Because of this process, you avoid wasted money and poorly matched springs. More importantly, you get a pistol that runs exactly the way it should.
