Slim 9 Booster Springs (6-Pack)

Fine-tune your Slim 9 for reliable cycling across a wider range of 9mm handguns.

Each Slim 9 comes standard with our 5-coil spring, designed to cycle reliably with most 9mm pistols. Some handguns, however, may require a lighter spring for proper function.

The Slim 9 Spring Six-Pack includes three standard 5-coil springs and three lighter 3-coil springs, giving you options to match your suppressor to different host firearms.

We recommend that you replace your spring every 1,000 rounds or once per year for the best performance.
