Grand Power has been building the K100 platform since the early 2000s, and the MK23 is the most refined version yet. The core of what makes this pistol different from the sea of tilt-barrel 9mms out there is a rotating barrel locking system. Instead of the muzzle rising and the breech dipping on each shot like a standard Browning-type action, the barrel on the K100 rotates roughly 45 degrees and travels in a straight line. The result is a lower bore axis and reduced felt recoil that you can actually notice at the range. It's the same principle you see in the Beretta PX4 Storm, but with Grand Power's own engineering approach using a cross-pin cam rather than a locking block.
Grand Power didn't cheap out on what they pack with this pistol. You get three 15-round magazines with bright red followers, four interchangeable backstraps to dial in your grip fit, and four optic mounting plates covering the most popular footprints including Trijicon RMR, C-More STS2, Shield SMS, and Noblex/Vortex Venom. The slide comes pre-cut for direct optic mounting, so you're not retrofitting anything. The front of the frame sports a MIL-STD 1913 Picatinny rail for light or laser attachments, and the controls are fully ambidextrous, covering both the slide stop and the magazine release.
This is a hammer-fired DA/SA pistol with a manual thumb safety on the slide. The first shot from a decocked position comes via a longer double-action pull, and every round after that fires single-action with a more defined wall and a shorter, crisper break. There's no decocker built in, so if you want to ride double-action again you'll manually lower the hammer. The grip texture on the MK23 is noticeably more aggressive than earlier K100 generations, and the redesigned front and rear slide serrations give you a much more positive purchase when working the action. Field stripping is a little unconventional compared to a Glock or SIG, so it's worth reading the manual the first couple of times, but nothing that takes long to get used to.
Overall dimensions come in at 7.96 inches long, 5.24 inches tall, and 1.43 inches wide, with a weight of about 27.7 ounces with an empty magazine. It's a full-size gun, comfortable at the range and on a duty belt, and the rotating barrel's recoil management makes longer sessions noticeably more comfortable than comparable 9mms.
The rotating barrel system keeps the barrel moving in a straight line rather than tilting up at the muzzle like a traditional Browning-style action. This allows for a lower bore axis and reduces the amount of muzzle flip you feel on each shot. In practice, the K100 MK23 shoots noticeably softer and flatter than most full-size 9mms, which makes it easier to get back on target quickly.
The slide is pre-cut for direct optic mounting and ships with four adapter plates covering the Trijicon RMR, C-More STS2, Shield SMS, and Noblex/Vortex Venom/Docter footprints. These plates are polymer rather than metal, so if you plan to mount an optic permanently, you may want to look at aftermarket metal plates down the road. Most of the popular compact red dots on the market today will fit one of the four included plates.
No, the MK23 does not have a decocker. It is a DA/SA pistol with a manual thumb safety. If you want to lower the hammer for a double-action first shot, you'll need to manually lower it with your thumb while maintaining trigger control. This is fairly standard for DA/SA pistols without a decocker and something any shooter familiar with the platform will be comfortable with.
It's one of the better-equipped full-size pistols in this regard. Grand Power includes four interchangeable backstraps in different thicknesses, so you can adjust the grip circumference to fit smaller or larger hands. Combined with the aggressive texture on the grip panels, most shooters should be able to find a configuration that feels secure and comfortable.
It's a bit more involved than something like a Glock or SIG. You'll pull the slide fully rearward, push down both takedown levers, then pull back slightly more to lift the slide off the rails. The guide rod is attached to the frame rather than captured in the slide, which is different from what most people are used to. It's not difficult once you've done it a few times, but it's worth reading the manual closely the first couple of sessions.
It ships with three 15-round magazines, which is more generous than most full-size pistols at this price point that typically include just one or two. The magazines feature bright red followers for easy visual confirmation of an empty chamber. At 15+1 capacity, you've got plenty of rounds on hand for training or range sessions.
