Optimize cycling and reliability in your SIG P320 X-Five Legion with this recoil spring assembly matched to a #14 spring rate for 9mm. The kit includes a heat-treated recoil spring manufactured to precise specifications and a precision guide rod (hardened steel, stainless option depending on SKU). The heavier #14 rate is tuned to control the Legion’s heavier slide mass, improve timing, and maintain consistent return-to-battery under demanding competition or high-round training conditions.
Engineered for drop-in compatibility with factory X-Five Legion slide and barrel combinations, this assembly helps reduce premature unlocking, improve extraction/ejection consistency, and resist spring fatigue during extended use. It’s ideal for competitive shooters, armourers, and owners who run high round counts or require a stiffer spring rate for specific setups.
Installation is straightforward for those experienced with striker-fired slide disassembly; always follow manufacturer instructions and perform a complete function and safety check after fitting. If you use suppressed barrels or non-standard slide/barrel combinations, verify compatibility or consult a qualified gunsmith before installation. Sold as a complete assembly (spring + guide rod).
