About
What it is, and why it matters
The Grand Power K100 Mk23 is a semi-automatic, hammer-fired pistol chambered in 9x19mm Parabellum, produced by the Slovak manufacturer Grand Power. It is a later production mark of the K100, whose defining feature is a short-recoil, rotating-barrel locking system that uses a cross-pin cam to rotate the barrel out of engagement during the firing cycle. This rotating-barrel action keeps the barrel in line with the frame during recoil, reducing muzzle flip and delivering a notably soft, controllable shooting impression. The Mk23 combines a polymer frame with an integral Picatinny accessory rail, interchangeable backstraps and a stainless-steel slide over a traditional double-action/single-action trigger mechanism, making it a versatile duty and sport pistol.
The K100's rotating-barrel action was conceived by Jaroslav Kuracina, a former Slovak Army weapons officer who first sketched the design in the early 1990s; the resulting pistol earned a reputation for unusually low felt recoil that made it a favourite on the practical-shooting circuit.
The K-series K100 is the hammer-fired DA/SA model of Grand Power's rotating-barrel pistol line (the striker-fired equivalent is the Q100). The Mk23 mark reflects incremental refinements to ergonomics, the rail and the grip over earlier marks such as the Mk6, Mk7 and Mk12.
