ISMI Recoil Spring Kit For SIG P365XL & X Macro 3.7" – 13lb, 15lb, 17lb, 20lb Chrome Silicon

Tuning your SIG P365XL or X Macro for different loads?

This ISMI recoil spring kit from NDZ Performance has you covered.

You get four different chrome silicon springs: 13lb, 15lb, 17lb (which is stock weight), and 20lb.

They're designed for the 3.7-inch barrel models like the P365XL, X Macro, and Spectre.

Made in the USA from high-quality chrome silicon, these springs will last.

Just swap them out depending on whether you're shooting standard pressure, +P, or suppressed.

They don't fit other models, so make sure you've got the right SIG.
