Wolff Recoil Calibration Pak – Reduced Power – RP Variable

Wolff Recoil Calibration Pak – Reduced Power (RP) Variable – 1911

Precision Recoil Tuning for Light Target and Competition Loads

The Wolff Reduced Power Variable Recoil Calibration Pak allows you to fine‑tune your 1911 specifically for light target ammunition and soft‑shooting competition loads. From the outset, this kit removes uncertainty by giving you the exact spring weights needed to achieve smooth cycling, reduced recoil impulse, and dependable function.

Rather than guessing or relying on trial and error, this complete kit delivers a structured tuning solution. Moreover, instead of purchasing springs one at a time, it saves both time and money. In fact, it provides approximately 20% savings compared to buying each spring separately. Even more importantly, it allows you to tune your pistol progressively—starting heavier and stepping down until you reach optimal performance.

Why Use a Recoil Calibration Pak?

Eliminate Guesswork and Tune with Confidence

In many cases, selecting the correct recoil spring weight is not immediately obvious. Therefore, Wolff designed this calibration pak to make tuning simple, systematic, and repeatable.

Specifically, the tuning process works as follows:

• First, begin with the strongest recoil spring.

• Next, test your pistol using your chosen ammunition.

• Then, gradually step down in spring weight until you achieve smooth cycling, consistent lockup, and reliable feeding.

Because of this methodical approach, you avoid wasted money and mismatched springs. More importantly, you end up with a pistol that operates exactly as it should with your chosen load.
