Wolff Recoil Calibration Pak – Extra Power Pak – XP Variable

Wolff Recoil Calibration Pak – Extra Power Variable (XP)

Precision Recoil Tuning for Your 1911

The Wolff Recoil Calibration Pak – Extra Power Variable (XP) delivers a proven, step‑by‑step solution for 1911 shooters who want to optimize recoil performance with confidence. Rather than guessing spring weights or, alternatively, purchasing individual springs one at a time, this complete kit provides multiple recoil options in a single package. As a result, you save money while, at the same time, achieving smoother cycling, improved reliability, and extended service life.

Moreover, every spring is manufactured from premium Wolff spring steel. Because of this, the kit delivers consistent performance not just initially, but over thousands of rounds.

Dial In Your Recoil System the Right Way

Simple, Step‑By‑Step Spring Selection

When the ideal recoil spring weight is unknown, this calibration pack makes the tuning process clear and repeatable. First, install the strongest recoil spring included in the kit. Next, test fire your pistol using your preferred ammunition. Then, step down incrementally through the spring weights until the pistol cycles smoothly and produces the recoil impulse you prefer.

Because of this structured approach, tuning becomes faster and more predictable. In addition, correct spring selection minimizes malfunctions while simultaneously reducing unnecessary stress on both the slide and frame. Consequently, your 1911 maintains reliable function and longevity over time.

Extra Power Variable Spring Advantage

Controlled Slide Movement from Start to Finish

Unlike traditional fixed‑rate recoil springs, Extra Power Variable (XP) springs progressively increase resistance as they compress. Initially, the slide moves freely, which promotes reliable feeding and consistent cycling. However, as the slide nears the end of its travel, resistance increases. As a result, the slide slows before contacting the frame.

Because of this controlled movement, shooters experience:

• Reduced felt recoil

• Minimized frame battering

• More consistent lockup

• Improved feeding across a broader range of loads

Therefore, this calibration pack performs exceptionally well with compensated pistols, hotter defensive ammunition, and lighter target loads alike.
