Keeping Traditions Alive Since 1953

Grand Power is a Slovakian manufacturer with deep military roots, and the Q100 is their striker-fired answer to a pistol that already serves as a national service sidearm. The Mk23 generation refines everything that made earlier Q100 variants popular, with updated slide serrations that are aggressive enough to be functional without tearing up your hands, an enhanced grip texture, and an optic-ready slide that accepts four of the most common red dot footprints. It comes to the US as a complete, ready-to-run package.
The rotating barrel is the heart of this pistol. Instead of the muzzle dipping and rising like a traditional Browning tilt-barrel design, the barrel moves straight back and rotates to unlock. The result is a lower bore axis, less muzzle flip, and a noticeably softer recoil impulse. People who shoot this gun back to back with conventional 9mms consistently comment on how flat it tracks between shots. The balance also plays into it: the barrel adds weight up front, which helps keep the nose down and makes fast, accurate follow-up shots easier to manage.
The trigger on this pistol works differently than most striker-fired guns. Most trigger safeties disengage almost immediately on contact, then the shooter has to travel through the rest of the pull to release the striker. The Q100 Mk23 reverses that feel: the safety spring requires deliberate pressure to disengage, after which the actual break is short and light. The result has been compared to a two-stage rifle trigger more than once, and it's one of the more pleasant striker pulls you'll find at this price point. Controls are fully ambidextrous, which is a nice touch for a duty-oriented pistol.
The frame is built on a glass-filled polyamide chassis with a steel insert housing the slide rails, so you get the weight savings of polymer with metal-on-metal contact where it counts. The slide and barrel use hardened steel with QPQ surface treatment for long-term durability. The included Picatinny accessory rail handles lights and lasers, and with three magazines and four optic adapter plates in the box, this gun is genuinely ready to work the day you take it home.
The rotating barrel moves straight back and rotates to unlock rather than tilting upward like a Browning-pattern action. This keeps the bore axis lower and the recoil impulse more linear, which translates to less muzzle flip and faster target reacquisition between shots. People who shoot it next to conventional 9mms routinely comment on how noticeably flatter it runs.
The Q100 Mk23 ships with four optic adapter plates covering the most popular footprints: Vortex Venom/Docter/Noblex/MeoRed 30, Trijicon RMR, CMORE STS2, and Shield SMS. That covers a wide range of common red dots right out of the box without needing to source additional hardware.
Most striker-fired trigger safeties release almost immediately on contact, leaving the shooter to travel through a longer stroke to break the shot. The Q100 Mk23 uses a heavier safety spring that requires deliberate pressure to disengage, after which the actual sear break is short and light. The feel ends up closer to a two-stage trigger than a typical striker pull, and it's one of the more distinctive aspects of the gun.
Yes, the Q100 Mk23 includes three 15-round magazines in the box. That's a generous inclusion compared to many competitors that ship with just one or two, and it means you're ready for a full range session without buying additional magazines right away.
The Q100 and K100 Mk23 share the same frame dimensions, rotating barrel system, 15-round magazines, and overall size. The key difference is the firing mechanism: the K100 is hammer-fired with a DA/SA trigger, while the Q100 is striker-fired with a single-action style pull. If you prefer the simplicity of a consistent striker trigger over a DA/SA system, the Q100 is the version to look at.
Grand Power designed the Q100 platform specifically for armed forces and personal defense applications, and the Mk23 updates that foundation with improved ergonomics, a rail for accessories, and an optic-ready slide. The full-size 4.25" barrel and 15+1 capacity make it more of a duty or home defense pistol than an everyday carry piece, though the relatively slim 1.34" width keeps it manageable for those who want to carry it.
