Wolff Recoil Calibration Pak – Ultra Light Reduced Power Pak

Wolff Ultra Light Reduced Power Recoil Calibration Pak – 1911 (Ultra Light Variable)

Precision Recoil Tuning for Ultra‑Light Loads

The Wolff Ultra Light Reduced Power Recoil Calibration Pak provides 1911 shooters with a precise and dependable solution for tuning pistols that run ultra‑light target loads or competition ammunition. When standard recoil springs prove too heavy, this kit offers a clear and effective alternative. Rather than guessing spring weights, you can systematically dial in the exact recoil setup your pistol requires for smooth, reliable cycling.

With this calibration pak, the tuning process becomes both logical and repeatable. You begin by installing the strongest spring in the set and then work downward. As a result, you quickly determine the lightest spring that still produces clean feeding, full lockup, and safe, consistent function. In addition, purchasing the complete kit saves money compared to buying individual springs one at a time.

Ultra‑Light Variable Spring Advantage

Smooth Cycling with Controlled Slide Speed

Each recoil spring in this kit features a variable‑rate design. Initially, the spring offers reduced resistance, allowing the slide to move freely with low‑energy ammunition. As the slide continues rearward, however, resistance gradually increases, slowing the slide near the end of its travel.

Because of this progressive resistance, recoil feels softer and more controlled. At the same time, sight recovery improves and overall handling becomes more predictable. Additionally, the variable‑rate design helps reduce frame stress and slide impact, even when running ultra‑light recoil springs.

Added Safety with Extra‑Power Firing Pin Springs

Beyond recoil tuning alone, this kit also includes three extra‑power firing pin springs. As a result, ignition timing remains safe and controlled, even when lighter recoil springs are installed. Therefore, you gain improved cycling performance without sacrificing reliability or safety.

---

How to Use

To begin, install the strongest recoil spring included in the kit. Next, test fire your pistol using your chosen ammunition. If cycling remains sluggish, move down one spring weight and test again. Continue this process until you reach the lightest spring that still cycles smoothly and locks up reliably.

By following this step‑by‑step method, you achieve consistent results while minimizing trial and error.
