The B&T APC9K, made up of the highest quality, meticulously machined components fitted with the Swiss-made precision that B&T is known for, brings a new level of performance and adaptability to the APC platform.

At the heart of this pistol’s operation is a hydraulic shock-absorbing buffer system that greatly mitigates recoil and enhances overall accuracy. More features of the BT APC9K include a 9mm-chambered barrel that is just 5.5 inches long; folding low profile adjustable sights for faster target acquisition; a dual auto-folding, non-reciprocating charging handle that hardly snags on loose clothing/equipment; ambidextrous controls including a safety selector switch; as well as improved lower receiver ergonomics including a flattop Picatinny rail for optics, an under-barrel rail for lights/lasers, a side positioned bolt hold open/release, and removable M4-compatible grips.

Shipped with a 33-round extended magazine, this B&T APC9K Pro for sale comes with a lower receiver outfitted to also accept widely available Glock magazines. The B&T APC9K Pro Glock magazine-compatible is in addition designed to accept an SB Tactical brace.
