Designed for full-size 9mm, .40 S&W, and .357 SIG Smith & Wesson M&P pistols, this Wolff 16 lb. recoil spring matches factory weight specifications.
Recoil springs are available in different weights to optimize performance, with lighter springs for reduced recoil and heavier springs for improved cycling with powerful loads.
Calibration Paks offer a range of springs to experiment with, including Extra Power and Reduced Power packs, each accompanied by factory weight striker springs.
