Yes, it’s another Grand Power review. Am I paid by them? No. Do I like their guns? Yes. I’m willing to take criticism for potential favoritism when you accept that I like them after having reviewed hundred of pistols and spent hundreds of hours in training at various institutions.

I like Grand Power for reasons. Given the comments from folks who thought the Q1S was a new release I thought I’d dig out another existing Grand Power you might not have heard of.

The Grand Power K22 (left) uses an open-slide design for enhanced reliability. The K22 X-TRIM (right) however manipulates more like a regular pistol.

The Grand Power K22 was the first .22LR semi-auto I ever encountered that ate just about anything. Some of the super-soft shooting subsonics wouldn’t cycle, but otherwise the pistol was unstoppable.

That’s largely due to the Beretta 92-looking open slide design. It’s nearly impossible for a round to fail to eject unless it also failed to extract.

The K22 X-TRIM is a more competition-oriented design with a “complete” slide that has been heavily skeletonized to reduce weight. No matter how skeletonized the slide is, it still has more mass than the regular K22 design. On my scale the X-TRIM’s slide is .8 oz heavier. More on that later.

The X-TRIM’s skeletonized slide is appealing. Fiber Optic sight and threaded barrel are also a plus.

What is it? 

The Grand Power K22 X-TRIM is a semi-auto .22LR pistol that mimics the handling, size, and control of the Grand Power K100. The frame, billet-steel internal chassis, controls, four backstraps, and all things user-related (aside from weight) is the same as the Grand Power main battleship including complete and truly-ambidextrous controls.

The internals are nestled in a billet steel chassis stamped with the initials of the smith who assembled it.

The “X-TRIM” designation is used for their competition-oriented models which generally includes skeletonization, a fiber-optic front sight and adjustable target rear sight, and sometimes enlarged safety levers to serve as thumb rests for quick shooting.

Magazines are ban-state-friendly 10-rounders sized to fit the regular full-size frame. Because the frame is the same size and the slide is the same shape of a duty-sized 9mm pistol, it fits holsters made for the K100 (providing there’s clearance for the threaded barrel. A tabletop look at the gun can be seen in the video below.

As you saw, aside from a fixed barrel and blowback operation, the Grand power K22 X-TRIM provides the feel and scale of a full-size gun with billet chassis to ensure long life. The pistol has a crisp trigger and is stamped with the initials of the smith who built it.

It’s a .22LR, but it’s not built like a toy. That’s a refreshing change that seems to be catching on in the industry. Though there is no de-cocker on the hammer-fired K22 X-TRIM, it is capable of firing in double action which is a nice feature with rimfire.

One of the X-TRIM upgrades is an adjustable rear target sight.

On the Range

I was looking forward to a repeat of my past experience with the regular K22 and curious if the extra .8 oz of slide weight would have any impact on reliability with weaker .22LR ammunition. To test that we tried eleven different loads ranging from 36gr to 60gr.

We had issues with poorly-formed Remington Gold Bullet rounds not wanting to feed. Aside from that, some loads seemed to be just a tad too soft for the K22 X-TRIM. The empty would eject, but the slide didn’t travel far enough to pick up the next round.

To see which loads worked best jump to the What’s For Dinner section of the Shooting Impressions video.

We also found the standard enlarged safety levers get in the way sometimes. With my larger hands I had to engage the safety to reach the slide lock. Fortunately low-profile safety levers are included in the box.

The range trip went about as expected. Being chambered for rimfire, the pistol is, of course, very comfortable to shoot, and you can’t fault a higher-trim gun for wanting higher-end ammunition.

For a competitive or defensive shooter wanting a .22LR to match their K100 or K100 X-TRIM, the K22 X-TRIM is a logical choice. I can also see a fit for those wanting a .22LR semi-auto that doesn’t feel like it was intended to be a youth trainer.

Ratings (out of five stars):

Reliability * * * * 
Like most .22LR semi-auto pistols not all loads will cycle reliably. The Grand Power K22 X-TRIM seems to prefer higher velocity ammunition of good quality.

Ergonomics * * * * *
Having carried and trained with the exact same frame size for years I might have some bias here, but between the four included backstraps I’m confident most normal human hands will feel at home, left or right.

Accuracy * * * * *
With .22LR this is be very ammunition dependent. I was able to create a ragged hole with SK ammunition.

Concealability * * * * 
A bit large for some, but no larger than the Grand Power K100 I’ve carried for years, climate and attire permitting.

Overall: * * * * 
The Grand Power K22 X-TRIM is a possibly overbuilt gun (who else uses a billet chassis in a .22LR?) that mimics a full-size gun as closely as possible, aside from weight and capacity. If you’re just looking for a plinker the regular K22 is less ammo-sensitive and costs $100 less.

        • Very ammo sensitive. Poor qc. Bought mine new and was sadly disappointed after previous experiences with Walther products. Word is they were made by Umarex. The bb gun folks.

        • I’ve shot a few iterations of the P22 over the years. A few were ammo sensitive. What I never liked about them is that the spring for the hammer stuck out about 1/8 of an inch on the bottom left of the hammer. Yes, you don’t put your hand there when firing. Problem is that once I noticed it, I couldn’t get it out of my head…”Why is this spring sticking out?”

    • Very true! The Sig Mosquito has one of the 3 worst triggers I’ve ever pulled. And there’s no good remedy. Made by Umarex. I’ve heard the new P322 is excellent though. The other atrocious triggers were the original S&W Sigma and the Polish P64. I once had a Kel-Tec P11 and it’s trigger was smooth and easy compared to the above 3!

  1. sig raised the bar… if more than ten is appealing.
    there’s this, which appeals. that smith, the ruger mk, buckmark, cz kadet, tenrds. revolv’s 5, 6, 9 whatevs.

  2. “Magazines are ban-state-friendly 10-rounders sized to fit the regular full-size frame.”

    In other words:. This full sized pistol holds a lousy 10 rounds. That sucks 😔

    Most 22 pistols hold 10 rounds. My Mark III 22/45, holds 10 as does my Ruger SR22. At least the SR22 is small and light.

    The Taurus TX22 and Kel Tec P17 finally dealt with this nonsense and gave us decent capacity magazines.

    • Both magazines for my P322 will now hold 23 rounds, one I swear contained 24 shots before locking back on empty. Maybe by winter they’ll hold 25 each. I also wonder how many the accessory 25 rounders will hold when they loosen up ?

      • By the way, it has been shot A LOT ; three weeks ago at a women’s intro to shooting at our range, they told me it had six bricks of Federal 510 run thru it…. I threw it in an ultrasonic cleaner overnight to see what color it was again, all it got during shooting was a snake run through it a couple of times.

    • The SIG P322 (21 rounds) and FN 502 (15 rounds) are two very good options that show limiting .22 pistols to only 10 rounds (outside of ban states…for now) is antiquated.

      • The K22 has been on the market for a long time, years before the higher-capacity .22s became a thing. Fingers crossed Grand Power will update the magazines.

  3. This is the first .22 pistol I have liked almost as much as my buckmark. That said I like my buckmark more still……

  4. How many mags are included, and are they hard / expensive to get… guns are imported from Slovakia?

  5. With two Grand Power reviews this week, I was interested in seeing earlier reviews of other GP models. I clicked on the GUN REVIEWS link and found that once there I could have the articles presented in different orders.

    So I got the drop-down menu and found that I was offered the list sorted by
    — Latest

    Notice something missing? Something built in to the old site layout of the gun review page? MANUFACTURER. Whoever decided to include “Random” and leave out “Manufacturer” needs to have a sternly worded poor performance review put in his personnel file.
