The K100 and GP6 use a rare locking system, shared by the Beretta Cougar, PX4 Storm, and Brügger & Thomet MP9 which employs a rotating barrel lock, which in the K100 and GP6's case is cammed by a cross pin. When the pistol is fired the barrel and slide move backward together for about 3/8ths of an inch while the barrel is cammed counterclockwise by a flat, twisting, helical "cut" in the barrel extension. Once the barrel and slide have moved back to the point where the barrel has twisted about 45 degrees to the left, the slide is free to continue traveling back while the barrel's travel is arrested by its interface to the frame via the barrel extension. On the K100 and GP6's barrel extension cam cut and cam tooth are replaced by a frame-embedded crosspin and a barrel extension "cut" with rounded surfaces which engage it. As such, there is no transfer block per say, and the barrel and barrel extension directly interface with the frame via the crosspin.

The Grand Power is being imported to the United States by STI International. 

The GP6 is an upgrade to the K100 which STI has contributed to.

With the GP6, STI International, Inc. delivers a compact SA/DA polymer pistol which serves equally well either on or off duty. With its integrated tactical rails, it is equally suitable for Military, Law Enforcement or Civilian carry.

Built on a light weight, highly durable polymer (Polyamide GF 30) frame, the GP6 incorporates integrated tactical rails and textured side panels, front and rear straps. The GP6’s all steel slide is tri-topped with front and rear cocking serrations and features a fixed 3 dot sight system. The controls consist of ambi-thumb safeties, an ambi–slide release, firing pin safety, and a user configurable magazine release for equal ease of use in either right or left handed configuration. The barrel is 4.25” in length featuring an innovative rotational lock up system. Long term durability testing units have fired more than 110,000 shots without any change in internal geometry. The GP6 comes standard with a storage case, 2 magazines, and sight keys.

The GP6 is currently available exclusively in 9mm.

MSRP $656.44
