Sig Sauer P320 X-Five Legion X-Change Kit 9mm Luger 5" 17-Rd Black Nitron

The Sig Sauer P320 X-Five Legion X-Change Kit is a factory-engineered caliber exchange package that upgrades an existing P320 into the X-Five Legion configuration in 9mm Luger without purchasing a second serialized pistol. The kit installs onto the customer's P320 fire control unit (the serialized component, not included), so this listing is sold as a factory accessory kit and does not require its own FFL transfer.

At the heart of the kit is a complete 5" stainless steel bull barrel mated to a Black Nitron slide that is cut for reflex optics and topped with a fiber optic front sight and an optic-adjustable rear sight. The grip module is Sig's signature TXG tungsten-infused polymer, whose added mass tames felt recoil and drives the pistol flat for fast follow-up shots. An X-Five magwell, grip weight, and 12lb recoil spring assembly round out the chassis.

Two 17-round 9mm magazines are included to feed the upgraded package. The P320's serialized fire control unit is the only major component not included, making this a true caliber exchange and upgrade kit rather than a complete firearm. Right-hand configuration. Brand New from Sig Sauer, made in the USA.
