Grand Power Duo – the K100 Mk7 and P1 Mk7

After they sent me the Stingray-C pistol, I got an email from Century International Arms, listing their new products. At first, I thought the email was simply an advertisement. Then I noticed they were asking which of their new products I wanted to review. I had to quell the urge to respond, “Everything.”

My eye settled on a pair of Slovakian handguns. The K100 Mk7 an P1 Mk7, both made by the company Grand Power. Before long, Dina Sanders of Century (who is quite helpful, by the way) had arranged for the Slovak Twins to be sent to me. Before long, my dealer called me up and said, “More pistols here for you. Damn, how do you do this?”
“What can I say? The CIA sends me guns.” Yeah, I know it’s a bad joke. Thankfully, there’s nothing bad about the Grand Power pistols.


These two pistols have almost identical frames. The only difference I can find is the recoil spring guide, which is slightly longer on the K100 Mk7. Both function in the same manner. Both are DA/SA and have a manual safety which can only be operated when the hammer is either in the half or fully-cocked position.

The safety is actually my only real complaint on the Grand Power design. I’m not particularly a fan of a safety in a double action pistol, preferring a decocker instead. But not every pistol is designed like a SIG and not every shooter prefers a decocking lever to a manual safety. So honestly, my big gripe is more of a personal preference than a fault in the design.

Trigger guard pulled away from the slide, pistol ready for disassembly.

Continuing along the vein of turn-offs, I initially found the pistols’ take-down annoying. It’s not as frustrating as the old Ruger MkI I learned to shoot with, but it’s unconventional to say the least. When disassembling the pistol, make sure to pull the trigger guard down and forward completely (not just a fraction of an inch). You then pull the slide to the rear and lift it off the frame.

Now as bizarre as a flexing, bending polymer trigger-guard might be, I actually got used to it. In fact, I grew to like it. Unorthodox though it may be, the take-down method is really quite simple. No need for tools or three hands. Re-assembly is similarly simple.

Due to the rotating barrel (more on that later), there’s no need to line the barrel up with the frame before inserting a takedown pin. No need to contort your body around the handgun as you try to re-assemble it. It’s as simple as retracing your steps, as you’ll see in the video. To be frank, I like the take-down method. I guess it grows on you.

The barrel is of an interesting, rotating design. Functionally, it’s similar to the Beretta Cougar. The barrel and slide move rearward until the barrel has rotated 45 degrees, at which point the slide continues back independently of the barrel. This results in a low bore axis, similar to the Steyr M-series and the Caracal series of pistols.

A steely gaze and ballistic nitriding are a winning combination.

Ambidextrous controls, including an ambi mag release are a real treat. Practicing with your weak hand simply becomes a matter of mirroring your regular movements, rather than learning to operate the pistol in a different way. Southpaws will love this feature.

The slide is QPQ treated, increasing its resistance to wear, corrosion and scratching. The barrel is carbonitride treated, increasing its hardness to between 52 and 54 HRC. This increases its wear resistance and is a major selling point for me. In addition to the reduced wear, this treatment has the added benefit of making the barrel incredibly easy to clean up. I can simply wipe it down with anything, which is superbly convenient. Of course, this may have something to do with the fact that I pre-treated the barrels with Froglube.

The trigger pull on double action is noticeable without being too heavy and is very consistent. The single action trigger pull is light and crisp. The feel of the pistol in my hand is excellent and if it weren’t, I would be able to quickly and easily fit it to myself using one of the four interchangeable backstraps that come with the pistol. While the manual indicates that the magazines hold 15 rounds, I’ve found that they will hold 16 without issue.

The magazine on the left is holding 15 rounds, the one on the right, 16.


Despite their lightweight, polymer frame, the Grand Power pistols have remarkably soft recoil. I found that I could do Mozambique drills at 10 yards with surprising ease and accuracy. And the pistols took whatever I could throw at them, be it cheap Russian ammo, moisture, or being buried in snow. Gritty or dirty, the Grand Power duo functioned well.

Though I enjoyed the Stingray-C, I have to say that the both of the Grand Power pistols beat it out for ease of carry, comfort in the hand and pure shootability. The slimmer grip on the Slovakian models is a real selling point for me. Even small women whom I’ve let try the P1 Mk7 have found it to be quite comfortable in their hands. While the K100 is a bit long for concealed carry by smaller shooters, the P1 is small enough to be hidden.

The trigger, controls and even the disassembly are all positive points to this unique line of handguns. If you’re in the market for a semi-automatic 9mm with ambidexterous controls, great ergonomics and superb corrosion resistance, I strongly recommend you check out the K100 Mk7 or the P1 Mk7 at Century International Arms.

    What type/brand of ammo would you recommend ??
    1) target practice
    2) self defense

    Also, can this weapon handle a +P load ??

    Please advise

  2. Mark says:

    I purchased the grand power k100 and I can only make one shot and the hammer won’t fall in. I have to push it back in, Am I Using The Gun Wrong or does it have some kind of problem?

  3. Brian says:

    Just to pass along my experience with the grand power P1 mk7, I purchased mine in November of 2015 and I have had nothing but problems with the trigger. Using double action, the gun works fine.

    Single action is where everything goes downhill. If I squeeze the trigger slowly, aiming for accurate on the target, the hammer will not fall about 75% of the time. If I smack the side of the gun, the hammer will fall. If I pull the trigger hard, the hammer will fall relatively reliably. The pistol was like this from day one. I sent it in to century for repair. When I got the pistol back, I put about 100 rounds through it with no issues. The next time I took it to the range, the issue had returned. I cleaned it after the first time at the range so it’s not a cleaning issue. Anyone else having this problem?

  4. Eon says:

    These look very similar to the new CZ-75 P09 which also has a decocker/safety that can easily be changed to decocker only. If this does the same, then we know it’s another CZ clone that CIA seems to have as its stock in trade – what with its EAA Witness, Polymer Wirness, Pavona, the BP9, and the Tangfolio. I’ll go with Slovakia, but NOT with anything coming out of Turkey.

  5. TJ says:

    One complaint. I can’t get the replaceable grips off nor can anyone who I asked to help. Got any advice?

  6. TJ says:

    Got the P1 for my wife specifically for the easy DA first trigger pull. She was having trouble with this on her S&W 6906. The light recoil helps her too. I am guessing a part of the recoil is soaked up turning the barrel.

  7. duane says:

    i shoot and own several brands from springfield to tanfoglio including k1 and p1. i find the grand powers to be the most accurate and triggers to be one of the best. although i don’t care for the takedown.i still rate them the best of all in quality and accuracy. if you are seeking something new you can’t go wrong with a grand power

  8. Kent Kumpula says:

    Do you know they have a “sport safety lever”?
    I´m sure it will be an awesome upgrade if you need to manipulate the safety fast, like IPSC style competition. Also, the X-calibur model has a even better and more smooth trigger and even less recoil.

    • 53gr says:

      Thank you for the information, Kent. I did not know that about the Grand Power.
      Honestly, if they made a version that replaced the safety with a de-cocker and moved the slide release to the rear, I could see a P1 Mk 7 (or I guess maybe they’d call it a Mk 8 ) replacing my SIG P226 (my absolute favorite handgun).

  9. The Father says:

    Myself and my two sons have purchased the Grand Power K100 M7 and P1 M7. They are awesome guns. Don’t miss out because they are not named Glock.

  10. Trey says:

    I noticed that you said that the P1 and the full sized K100 function the same, but was there a difference in recoil?

  11. Travis says:

    I’m relatively new to the handgun scene, and I stumbled across this gun on a website that I frequently visit. I’m often attracted to guns rhat are not “main steam” but find the MSRP of this gun to bit a bit higher then most that are new to the U.S. market. A person could grab a new Sig SP2022 for roughly the same price if not a touch less. I have not shot either, but wonder if given a choice which would be the better buy and why?

    • 53gr says:

      I love SIG pistols, though I have to say I’m not fond of their SIG Pro. I prefer a P226. But I really like the Grand Power pistols, especially the nitride treatment. I’d suggest that (if possible), you handle them both. Whichever feels better in your hand, buy.

  12. Al Buchmann says:

    The disassembly is not unique as it was designed by Walther for their PP model in 1929.

    • 53gr says:

      Al, I used the word “unique” when describing the line of pistols, not the disassembly feature. Yes, Walther had a hinged trigger guard dissasembly. This is a new twist on that idea, using a flexing polymer frame. All in all, it’s a neat design, even if it takes a little getting used to.
