The K100, featuring an SA/DA trigger mechanism, embodies the stringent criteria set for versatile firearms, catering to the needs of practical enthusiasts and specialized military units alike. Crafted with ergonomics in mind, it aligns seamlessly with the diverse requirements of these shooters. The front section of the frame is equipped with a universal tactical Picatinny rail MIL STD 1913, adding adaptability to its design. As the evolution of the well-regarded Mk6 and Mk7 models, the K100 Mk12 introduces a notable upgrade, offering three interchangeable backstraps. This flexibility not only enhances the shooter's comfort but also positions the gun as an ideal choice for multi-user shooting practices. The refined ergonomic features of the K100 Mk12 contribute to an improved handgrip during shooting, allowing the shooter to maintain focus on the target both physically and mentally. In essence, the K100 exemplifies a harmonious blend of precision engineering, adaptability, and user-centric design, making it a preferred choice for a wide spectrum of shooting applications.

    Grand power k100 mk12

    Posted by Douglas on Jun 16th 2024

    Put a couple hundred rounds down line no FF or eject, like the gun but will upgrade the front sight (it's a CZ75) type, so there's lots of options.

    High quality feel to this soft shooting gun. One of the mags was causing misfeeds, but cleared after about 100 rounds

    GP K100 9mm

    Posted by RB Avery on Apr 17th 2024

    I have both the Grand Power and the Beretta PX-4 storm in.40 s&w, my GP is so accurate that at the range if another shooter has a red dot and I have open iron sights we are dead even, he has no advantage! At 15-25 yards it’s a wash. The reduced recoil and smooth trigger do make a difference, follow up shots or shots at 5-10 yard line your red dot is NOT an advantage if I am shooting a GP 9mm or a Beretta PX-4. Quality of construction also favors the GP when compared to a Walther PDP, I should know because I have a Walther. A 1965 James Bond P series and a PPQ

    this pistol is by far the best of all I tried, excellent trigger and the recoil is noticeable less than Glock, even less than CZ 75. the rotating barrel does make the different for accuracy and recoil management .

    Love Grand Power so much I bought another one!

    Posted by CJ Ryan on Feb 7th 2024

    I am correcting a previous review. My previous review was supposed to be for the Q100 handgun by purchased several weeks earlier. By the way loved it! I rated it five stars This review is pretty much the same. The K100 functions or I should say shoots almost exactly the same as my first purchase, the Q100 model. The quality of the firearm is top-notch. The shooting experience is different from your standard Browning locking breach you find an almost all other handguns. I can tell the difference and enjoy the experience of firing this handgun. I am going to be purchasing the 10 mm version next. I am looking forward to acquiring the firearm. I highly recommend purchasing Grand Power ower handguns to anyone who is interested in a different shooting experience.

    Fantastic 9 mm handgun!

    Posted by CJ Ryan on Feb 7th 2024

    Outstanding 9 mm handgun from Grand Power! Several weeks ago I purchased the Q100 Striker fire 9 mm handgun to sample the rotating barrel and smooth recoil I have read about. The claims are true! It does shoot slightly smoother than other handguns. I make that statement because I went down to my range and sampled the grand power against a PSA Dagger, a Canik DA, a Canik Rval SFX, an older Ruger P89 and a Girson Beretta M9 series copy. I can definitely state the Grand Power Q100 does shoot slightly smoother than any of the other pistol models mention previously. By smoother I am talking about the felt recoil in my hand. I also enjoy the grips of the pistol. It is important that the shooter be comfortable with the weapon. I fired several hundred rounds at the range during this test and pleasantly surprised with the results. The factory sites were dead on out to 25 yards. The feel and balance in my hand was very good. The reviews I read or watched were correct on the handgun. I will be purchasing other firearms from GP in the future to add to my collection. I would definitely recommend any shooter to consider and purchase a Grand Power firearm.

    GP K100 m12

    Posted by D on Nov 7th 2023

    My first purchased Grand Power firearm. Shipping was quick by Global Ordnance; FedEx to my FFL dealer. Taken to the range yesterday. Shot both Igman NATO 124 grain and Remington UMC 115 grain ammunition [150-200 rounds]. No hiccups whatsoever and very accurate firearm right out of the box. VERY low recoil with the rotation barrel design. I'm considering the GP P1 M12 for purchase as well.

    Good shooter

    Posted by Robsurp on Jun 27th 2022

    Didn't know what to expect, ordered it with my stribog. When I got it, it felt kind of cheap. However, after playing with it durring cleaning it is a fantastic design and performed awesome with 100 rounds
