Tanfoglio springs for Stock II and Limited platforms covering mainspring and recoil spring kits used to tune DA/SA pull weight and reliability for USPSA and IPSC competition. Brands include CGW and Tanfoglio factory, offering reduced-power mainsprings that lighten double-action trigger pull while maintaining reliable primer ignition across a range of competition ammunition. Recoil spring kits cover a range of weights matched to major and minor power factor loads, letting shooters keep the slide cycling reliably without excess battering on the frame during a high-round-count match weekend. Spring kits with multiple weights let shooters fine-tune DA pull incrementally rather than guessing at a single reduced-power spring, which matters when chasing a specific trigger feel within Production or Limited division rules. Compatibility covers Stock II, Limited, and Gold Custom platforms sharing the CZ-pattern action architecture. Whether you're lightening a DA trigger for competition or tuning recoil spring weight for a specific load, spring selection is foundational to both reliability and trigger performance on a Tanfoglio.
