Restore or upgrade the cycling performance of your SIG P320 X-Five Legion with this recoil spring assembly matched to the X-Five Legion platform and tuned to a #12 spring rate for 9mm configuration. The assembly includes a heat-treated recoil spring manufactured to precise specifications and a precision guide rod (available in hardened steel with a stainless option depending on SKU).

Specifically selected for the X-Five Legion’s heavier slide and competition setup, the #12 rate helps ensure consistent spring compression, correct timing, and dependable return-to-battery action under high-round counts and demanding use. Ideal for competition shooters, range use, and armourer maintenance, this assembly reduces timing-related malfunctions and improves extraction/ejection consistency when paired with factory or Legion-spec barrels and slides.

Installation is direct for those familiar with striker-fired slide disassembly; always follow manufacturer instructions and perform a full function and safety check after fitting. If you run a suppressed barrel or non-standard slide/barrel combinations, verify compatibility and consider consulting a qualified gunsmith. Sold as a complete assembly (spring + guide rod).
