Sig Sauer competition pistols and match parts support P226, P229, P320 X5, P365, and Legion builds from first-round zero to the last stage of a major. The P320 X5 Legion remains a strong Carry Optics or Limited foundation, with its weight-forward X-Series format, optic-ready slide options, and modular grip system. P226 and P229 pistols continue to serve USPSA Production and IDPA shooters who want a hammer-fired trigger system and established match support, while P365 components cover compact-platform needs. Stock Sig Sauer factory parts alongside flat triggers, grip modules, guide rods, springs, magazine components, sights, holsters, and competition upgrades from respected aftermarket makers. Legion-oriented parts help refine trigger reach, grip texture, balance, and reload access without losing the platform's familiar controls. Verify the exact pistol generation, caliber, slide cut, grip module, and magazine pattern before selecting hardware. P320 X5 builds can be configured around an optic, division-legal magazines, and recoil tuning; P226 and P229 setups can stay focused on Production or IDPA compliance.
