Grand Power Q1 Mk23 9mm Luger 3.66" 15+1 Black Striker-Fired Pistol

The Grand Power Q1 Mk23 (UPC 8588005808675) is a compact striker-fired 9mm Luger pistol manufactured in Slovakia and imported by Global Ordnance. This is the full-capacity striker-fired variant, shipping with a 15-round magazine. The Mk23 series is Grand Power's optics-ready generation — the steel slide is factory-milled for micro red dot mounting and ships with four adapter plates.

The Q1 Mk23 is built around Grand Power's rotary-locking barrel system. Unlike conventional tilting-barrel designs, the barrel rotates inside the slide to lock and unlock, keeping the bore axis aligned throughout the firing cycle. This produces noticeably less muzzle flip and felt recoil than comparable tilting-barrel striker-fired pistols. For shooters coming from platforms like the Glock or Sig P320, the difference is immediately apparent — the Q1 Mk23 tracks flatter and returns to target faster.

The striker-fired trigger system provides a consistent pull weight from the first shot to the last. An integrated trigger safety blade prevents the trigger from moving unless the shooter's finger is properly positioned on the trigger face. A passive firing pin block adds drop safety. There is no manual thumb safety — the Q1 is designed for simplicity and speed, similar in operating philosophy to a Glock but with the recoil advantages of the rotary barrel.

The 3.66-inch bull barrel is bushingless, machined from a single piece of steel. No barrel bushing or link is required, which simplifies takedown and reassembly. The barrel hood mates precisely with the ejection port for consistent lockup and accuracy.

The polymer frame uses an embedded steel chassis for structural rigidity at reduced weight. The grip features interchangeable backstraps for adjusting the circumference and palm swell to fit different hand sizes. A Picatinny accessory rail is molded into the dust cover for weapon lights and lasers. All controls — slide stop and magazine release — are fully ambidextrous.

The Mk23 slide features enhanced front and rear serrations for positive grip during press checks and malfunction clearance. The factory optics cut accepts micro red dots using one of four included adapter plates, covering Vortex Venom / Docter, Trijicon RMR, C-MORE STS2, and Shield SMS / RMS footprints. Fixed iron sights come installed from the factory and co-witness with most micro red dots.
