USA – -(  Beginning with a prototype in 1998 the Grand Power line of pistols has been ever-expanding. 12 Grand Power Handgun series are currently available in the United States thanks to their importer Eagle Imports.

Those who have known Grand Power pistols know them for their excellent triggers, true and complete ambidextrous controls, and unique features. I’ve been a fan of the company since I first tried their flagship model, the XCalibur Pistol, and put 15 rounds into two ragged holes at 10 yards.

With such a reputation for incredible accuracy and a trigger crisp enough to enable the shooter, why risk a striker firing system mushing it up?

As a gun-writer I shoot every weekend, and usually that involved trying at least two guns for the first time. Perhaps that has made me lazy in that single-action triggers are generally quicker to learn. They have take-up, a wall, and then break. Striker-fired guns tend to lack that, or at least have a less-defined wall, but where they make up for it is in reliability. By sealing up the action inside of the slide there is less chance of debris obstructing it. While I understand this, I was a little concerned about how Grand Power’s first hammerless would actually shoot. The Grand Power trigger was one of my favorite features, so why change it? I love chocolate ice cream and now I’m being served strawberry from the same ice cream maker. Will it be any good?

Grand Power Q100 Pistol

Aside from the firing mechanism the rest of the gun is the excellence we’ve come to expect from Grand Power. Anyone who gets remotely freaked out about engineering or manufacturing may need to move to a private and lockable room before reading further. As a company founded and lead by a certifiable gun nut (founder Jaroslav’s first design was sketched when he was still in high school), Grand Power’s a machinist’s playground.

To start, take a look at the rotating barrel. Breaking free from the browning design, Grand Powers rotate to lock and unlock. This permits the barrel to be mounted lower in the pistol and thereby direct recoil more through the wrist rather than over it. The smooth rotation also reduces friction points in the cycling of the firearm. Smoother cycling reduces perceived recoil. The next time you encounter one of these pistols at a gun shop have the clerk field strip it so that you can see the barrel for yourself. What looks like a color swirl on the picture to the right is actually the reflection of the light, camera, and hand of the photographer trying to capture the mirror-like surface and all of its contours.

Anyone who has experienced ruptured brass will rejoice to know that the chamber is fully supported. Those who know otherwise can comment below, but I venture to argue that a fully-supported chamber can aid in accuracy as the brass expands more uniformly thereby providing more consistent ignition and thrust.

Inside the frame of Grand Power pistols resides a steel chassis much like that which gained the Sig models popularity. In the single-action/double action models this chassis contributes to the crisp and predictable trigger pull much in the way a 1911 breaks. What it accomplishes in a striker-fired design I do not know other than streamlining production, but I can say the pistol performed admirably without a single hiccup that couldn’t be blamed on the shooter. As shown in the video above we tried loads ranging from 60gr to 147gr hollow-points and the alternative PolyCase ARX to see what would cycle. Every round fired and cycled without an issue and even the 60gr was able to lock the slide back when empty. The slide lock can be attributed to the relatively-reduced energy required to operate. The reliable feeding, no doubt, has something to do with the polished feed ramp and short, minimalist path from the magazine to the chamber.

An added benefit that I had not expected in turning the hammer-fired K-100 into the striker-fired Q-100 is that the top of the slide can be physically longer. Without a need for hammer clearance the slide’s top is able to extend longer; moving the rear sight farther back. This results in a longer sight radius on the same-sized slide.

We all know that a longer sight radius makes slight movements of the hand less obvious resulting in a more confident shot and easier sight alignment.

When it comes to fit in the hand there are few options that offer more options than the four included backstraps. These backstraps change not only the palm swell, but also heel shape and sides of the stock. No punch is required to change them, simply pry off the current and snap on the new. The Q100 makes my seventh Grand Power pistol and I must admit that I haven’t yet figured out which backstrap is my favorite as they each seem to offer something for both the banana-handed male like myself and the smaller-handed female like Erika.

What internal safty features do grand power have
Anything like cz


I have been using the GPK100 since the days of STI GP6 Mk6. Love it. Upgraded to the Mk7 version for the backstraps. Love it. Just got the new Q100. Have not time yet on the range. However, the trigger is no where as nice as the K100. Spongy, longer reset. As someone else had mentioned about mags, too bad mags are not available at a cheaper price than $50ea. Other imports have mags almost half that cost.

Guys, I got the Q100 yesterday. The ejection with 115 grain Brass Blazer ammo (my preferred range ammo, that never gave me any trouble with any other gun) was producing Stove pipes (failure to eject). It happened 10 times within first 2 mags, and then some…. Also, the ejection pattern is chaotic in direction and generally quite weak. Some shells were throthrown in my face and on my hands. This really SUCKS. I don’t understand how everyone is raving about the gun and NO ONE mentioned it, though when I review the videos and pay attention to the ejection –… Read more »


If only the magazines would be more affordably priced. $50-75 is not reasonable. If Canik and EAA can sell perfectly decent magazines for $25-27 dollars, why can’t GP/Eagle Imports? They’re essentially just CZ-75 magazines with a centered square hole for the magazine release.


I wwonder if we’ll see a striker fire in the P11. Absolutely love my P11.

Everybody relax – MSRP $574 at Eagle Imports website. Suppose that’s correct? Of course I live in the Golden State, so my chances of owning one at laughable.

Jo Ann

Ok, I’m a grownup – just what IS the price?

James Bailey

‘Full Specs’ to me means the price as well!!


As I posted elsewhere, be careful…you might like the Grand Power too much. I liked the first one I got, the DA/SA hammer fired K100, so much I ended up getting a P11 and an Xcaliber. Excellent guns, even if little known on this side of the pond…very well known and respected in European competition circles.

If you want to see something cool, watch a YouTube video of the Grand Power K105…it’s a full auto version of the K100.

Graham Baates

The same thing happened to me. It started with the XCalibur, then P11, K100, CP380, P40 in 10mm…
