The P320-XFULL’s performance stems from its stable 5-inch bull barrel and low bore axis, which directly manages recoil impulse for faster follow-up shots. Chambered in 9mm, it balances capacity with manageable ballistics. The modular Fire Control Unit (FCU) is the serialized component, enabling legal frame swaps and caliber conversions, making this a versatile platform for both competition and defensive training.
