About this product
Grand Power Q1S MK23 9mm 3.66in Compact Pistol Black
If you carry in the city, you know the trade-off between firepower and concealment. The Grand Power Q1S MK23 9mm 3.66in Compact Pistol Black solves that equation with a grip that disappears under a tee shirt and a rotating barrel system that keeps your sights on target when seconds count. This is a purpose-built compact that doesn't compromise on control or reliability.

Key Features
- Locking Barrel Rotation Mechanism – Reduces felt recoil and muzzle flip by rotating the barrel as it unlocks. Why it matters: faster follow-up shots in tight spaces, less fatigue during range sessions.
- Reduced-Profile Grip with Textured Surface – Slimmer than the Q100 frame, with aggressive texturing for a locked-in hold. Why it matters: conceals easier under a shirt, stays planted in your hand during rapid fire.
- Optic-Ready Slide with Four Baseplates – Milled for micro red dots, includes 4 adapter plates for popular optics. Why it matters: mount your RMR or Holosun without sending the slide to a machine shop.
- 3.66-Inch Barrel – Balances ballistic performance with carryability. Why it matters: enough barrel length for reliable 9mm expansion, short enough to appendix carry without jabbing your thigh.
- Multiple Accessories Included – Ships with 2 magazines, cleaning kit, hard case, and a cable lock. Why it matters: ready for the range or holster out of the box, no extra trips to the store.
Who It's For
This is for the urban CCW holder who lives in an apartment and wants a pistol that pulls double duty. You need something that fits a nightstand safe, rides comfortably in a IWB holster, and handles defensive scenarios from carjacking to hallway intruders. The Q1S MK23 is built for that lifestyle—compact enough to forget you're carrying, accurate enough for 25-yard shots if you do your part.
Pros & Cons
- Pros: Low bore axis and rotating barrel reduce muzzle rise; slim grip for smaller hands or deep concealment; optic-ready without extra cost; reliable with ball and hollow points.
- Cons: Trigger has a longer reset than some striker-fired competitors; aftermarket holster options are limited compared to Glock or Sig; the rotating barrel system requires more frequent cleaning to stay reliable in dusty conditions.

FAQ
What magazines does the Grand Power Q1S MK23 use?
It uses Grand Power Q100-series magazines. The pistol ships with two 10-round or 15-round mags depending on your state. Mec-Gar also makes compatible mags.
Is the Grand Power Q1S MK23 good for concealed carry?
Yes. The slim grip and 3.66-inch barrel make it ideal for IWB and appendix carry. At 24.5 ounces, it's light enough for all-day wear but heavy enough to soak up recoil.
How does the rotating barrel system work?
The barrel rotates 15 degrees as it unlocks from the slide, redirecting gas pressure to push the muzzle down instead of up. This reduces muzzle flip by about 30% compared to a standard tilting-barrel design.
Can I mount a red dot without a gunsmith?
Yes. The slide is pre-milled and ships with four baseplates for popular footprints (RMR, Docter, C-More, Shield). You just screw on the plate and optic.
What holsters fit the Q1S MK23?
Holsters for the Grand Power Q100 or Q100S often fit the Q1S MK23. Brands like Black Rhino Concealment and Craft Holsters offer dedicated options. Verify retention before carrying.
Ready to Carry?
Over 200,000 Grand Power pistols are in civilian hands worldwide. The Q1S MK23 brings that proven rotating barrel tech into a package that hides under a hoodie. Grab yours and get the reliability of a design that's been battle-tested in Slovakia's military trials.
