KH9 Covert: Folding Karl's Hobby

The B&T KH9 Covert is a uniquely engineered platform built for discreet carry, rapid deployment, and uncompromising 9mm performance. Inspired by the Italian Spectre M4 and brought to life as a personal passion project of B&T founder Karl Brügger, the KH9 embodies a blend of heritage, creativity, and modern Swiss precision that sets it apart from traditional PCCs and PDWs.

Its defining feature is its fully collapsing architecture: a folding magazine well, folding pistol grip, and telescoping stock work together to create an ultra-slim footprint ideal for backpacks, messenger bags, and compact transport setups. When deployed, it delivers the accuracy, controllability, and reliability expected of a B&T firearm.

A linear hammer system, two-piece bolt assembly, and ambidextrous controls contribute to its smooth shooting characteristics and intuitive handling. The KH9 Covert is compatible with APC9-pattern magazines and offered in both pistol and SPR configurations, with limited-edition 25-round coyote or black magazines included.

A cold hammer-forged, tri-lug barrel ensures durability, precision, and fast suppressor attachment—completing a platform purpose-built for discrete capability without sacrificing performance.
Whether for personal defense, recreational use, or a refined collection, the KH9 Covert is B&T’s most unconventional and adaptable 9mm design yet.
