s one of the flagships of B&T, the APC PRO line represents a breakthrough in customization and modularity on a pistol-caliber platform. Every component is of the highest quality, and is meticulously machined and fitted with the Swiss-made precision that B&T is known for. The APC PRO itself is equipped with several major upgrades such as enhanced lower receiver ergonomics and a side positioned bolt hold open/release. The APC PRO also sports a non-reciprocating, auto-folding charging handle to reduce the risk of snagging on loose clothing/equipment. At the heart of the APC system is the hydraulic shock-absorbing buffer system which greatly mitigates recoil and enhances overall accuracy.
