The .22 Magnum pistol is a rare bird, but we pick four top options in the caliber to satiate even the most finicky rimfire fan.
A semi-automatic .22 Magnum pistol โฆ cue crickets chirping.
Popular as the souped-up rimfire cartridge has proven over the past 60 odd years itโs never really conquered the pistol market. Revolvers, those chamber in whatโs properly known as the .22 Winchester Magnum Rimfire (.22 WMR), shooters have them coming out their ears. But pistols tread on hen's teeth territory.
Whatโs the deal? Thereโs a couple of things at play stacking the deck against the widespread production of .22 Magnum pistols.
More than anything, the cartridge poses a tricky proposition. Rimmed cartridges are notoriously finicky in box magazines. Load them incorrectlyโthat is, hitch a rim behind another rimโand youโre managing a failure to feed. Jam-o-matics arenโt a load of fun, even if they deliver more punch to their destination.
If that isnโt enough, the .22 Magnum is a high-pressure cartridge that doesnโt play nice with straight blowback systems. Instead a delayed blowback operation is required to function properly. The task is tall in a pistol, requiring elegant engineering. This leads to the next big issueโcost.

Inherently, given a delayed blowback operation is more mechanically complex than a straight blowback, it cost more to engineer, manufacture and QC. Faced with this, the suits crunching numbers at gun companies have a simple refrain: Screw it, make a .22 LR pistol! If theyโre ambitious, maybe theyโll roll the dice on a .22 Magnum revolver. Grimace if you must, but their calculus isnโt skewed.

Plus guns chambered for standard-bearer .22 LR not only cost less up front, but also in the long run. Savvy shoppers (in normal times) pay a dime or less per trigger pull of .22 LR; for .22 Magnum, theyโre ponying up nearer to a quarter per pop. That adds upโparticularly for plinking and pleasure shooting. Given these factors, itโs almost a wasteland when it comes to .22 Magnum pistols โฆ almost.
There are some notable exceptions, so we picked out four semi-autos that have what it takes to scratch the magnum-rimfire itch. But, be warned, the world isnโt exactly awash in options. So, as your mother most likely told you on more than one occasion, beggars canโt be choosers.
How I Chose The Best .22 Magnum Pistols
This was an easy task overall, because pickings are slim in the .22 Magnum pistol market. But I still did my due diligence and put each pistol through its paces honing in on each gun's accuracy, ergonomics, price and overall reliability. The last one is an important point, because this class of pistol has a rough track record. After many rounds down range, some hard running of each gun, I came up with these as the top picks in .22 Magnum pistols.

Walther WMP

Pros:
- Ready for a modern pistol red dot and weapon light out of the box
- Ambidextrous
- Closest ergonomics to a standard centerfire full-size pistol
Cons:
- Relatively new, so has little real-world use and is yet to establish a reputation.

Released in 2022, the WMP or Walther Magnum Pistol came as a bit of a surprise. It's certainly on the more “tactical” side of handguns due to its inclusion of features like an optics-ready slide, and that isn't typical of .22 Magnum pistols.
The WMP is a full-size, polymer-framed handgun with a 4.5-inch barrel and 15-round magazine capacity. It has a typical accessory rail on the underside and an optics-cut slide on top. The front sight is also fiber optic. The pistol is fully ambidextrous as well, in part thanks to its unique Quad release mechanism that features both a traditional button mag release and a Walther-style paddle release on each side.
These features combine to make the WMP a very versatile pistol, just like the cartridge it fires. With its optics-ready slide, it could be used in competition, for pest control or just for having a blast at the range. Regardless of your reason for wanting one, we believe that the new WMP will soon establish itself as one of the best .22 Magnum pistol designs on the market.
Overall, I found the pistol a pleasure to shoot and very accurate out to 15 yards. The Walther fit my hand perfectly, even if I do find the grip a bit unappealing to the eye. And all but for a few rounds at the beginning that failed to eject, I found the WMP very reliable.

Walther WMP 22 WMR
Rock Island Armory XT 22 Magnum

Pros:
- Traditional 1911 feel and look
- Decent single-action trigger
Cons:
- Must buy the XT Pro variant if you want to mount an optic, and it has an MSRP $150 higher than the standard model
Rock Island XT 22 Magnum Specs
Caliber: .22 Magnum
Barrel Length: 5 inches
Overall Length: 8.54 inches
Weight: 40 ounces
Magazine: 14 Rounds
MSRP: $599

With a fraction of the fanfare it deserved, Rock Island launched its XT line a few years ago. Yet, the pistol deserves credit, it delivers on all accountsโaffordability, dependability and, above all, accuracy.
No surprise from the Filipino company that made its bones with economical 1911s, its .22 Magnum pistol cuts the same figure and has the same feel. The similarities stop there, but it's still great news for anyone who loves the grip angle or aesthetics of the 1911. The XT is a top-ejector affair, somewhat reminiscent of a Beretta 92, with a unique two-piece barrel design thatโs part of the pistolโs delayed blowback operation. It sounds complicated, but honestly is a fairly straightforward system that pays dividends. Not only does it run like a top, but it makes for a trimmer, more manageable gun.
I found the XT has a real sporty feel to it, so it's easy for to imagine it would do well in a competitive setting. I think the flat-top Pro model would make an interesting option for this with its full-length Picatinny rail on top of the slide. Certainly, the pistolโs configuration lends it to self-defense, though, I don't believe the caliber should be anyone's first choice. And even though itโs light, the XT is too large to make it a backup option.

Kel-Tec PMR-30

Pros:
- Very high capacity
- Most affordable (can be found new for about $350 at time of writing)
- Lightweight
Cons:
- Some users report reliability issues when the mag is loaded by hand rather than with a speed loader
Kel-Tec PMR-30 Specs
Caliber: .22 Magnum
Barrel Length: 4.3 inches
Overall Length: 7.9 inches
Weight: 14 ounces
Magazine: 30-round
MSRP: $510

When the Kel-Tec labs unleashed this Frankensteinโs monster around a decade ago, it was met withโto be honestโfurrowed brows. (Mine included.) What exactly was the angle of the plasticity, futuristic-looking .22 Magnum pistol?
Not easily categorized, the new-wave heater nonetheless shouldered its way into the market, if for no other reason than sheer, unadulterated firepower. There arenโt many problems that canโt be solved with 30 rounds on tap.
Yes, for those unfamiliar with the PMR-30, thatโs its hookโcapacity. Which, when you put your mind to it, makes this fairly difficult to classify pistol quite useful for many applications. Backwoods insurance policy, rucksackโs best friend, inconspicuous truck gunโin essence, Jack-of-all-trades. Perhaps its most agreed-upon role is as a bug-out bag pistol.
Next to firepower, the PMR-30โs light weight is its greatest asset. Even fully juiced, it doesnโt weigh much more than a centerfire duty pistol. And for all its idiosyncrasies, the pistol is easy and comfortable to run, even delightful. It fit my hand well, boasted a snappy trigger and, thanks to Hi-Viz sights, is relatively quick on target. I like this gun and think it offers a lot for someone in the market for something a bit different, but functional.

Smith & Wesson M&P 22 Magnum

Pros:
- Potentially most reliable option with correct ammo due to TEMPO system
- Very high capacity
- Optics-ready
Cons:
- Ammo sensitive
- A bit pricey
- Relatively new, so has little real-world use and is yet to establish a reputation.
S&W M&P 22 Magnum Specs
Caliber: .22 Magnum
Barrel Length: 4.35 inches
Overall Length: 8.4 inches
Weight: 22 ounces
Magazine: 30-round
MSRP: $649

Featuring the same TEMPO barrel system that debuted in Smith & Wesson's M&P 5.7, the M&P 22 Magnum has a lot of advantages over .22 Mag. pistols with more traditional operating systems. That's because the TEMPO system doesn't allow for the barrel to cam open until after the bullet passes the gas port, increasing both reliability and accuracy. The only downside here is that the system only works well with certain types of ammo, but Smith & Wesson has already done extensive testing so you won't need to guess. Use one of the several officially-recommended loads and you shouldn't have any issues.
Besides the M&P 22 Magnum's potential for great reliability, it has some excellent features as well. I, like anyone, love its 30-round magazine capacity. Kel-Tec had that market cornered for years, but now if you want a deluxe version of the PMR-30 you have the M&P to consider too. The pistol also comes ready to direct-mount RMSc-footprint optics and features a fiber optic front sight, a flat-faced trigger, a Picatinny rail and a thumb safety.
Of these, I appreciated the ability to mount an optic, which take the pistol a whole new level. As for the TEMPO system, working off S&W's cheat sheet and shooting CCI Maxi-Mag, the pistol ran flawlessly for me. The only hitch I really found in the .22 Mag is its price tag, which runs a bit more than what many would like to drop on this class of pistol.

.22 Magnum Pistol FAQ
.22 Magnum pistols primarily shine on the ranch, in the woods and on the range. By that, we mean that .22 Magnum is an ideal round for pest control around one's property, small game/varmint hunting and plinking. A .22 Mag. pistol could be used for self-defense, but for most people, there are a lot of better options available.
Yes. Due to its larger case capacity, .22 Magnum rounds are loaded with more powder which results in higher velocities than what .22 LR is capable of producing. For our more in depth comparison of these two rounds, read .22 WMR Vs .22 LR: Application Defines This Rimfire Rumble.
You can, but we generally don't recommend it. There are much better self-defense cartridges out there that offer more power and better reliability, but these come at the cost of greater recoil. For individuals with hand strength issues or other handicaps, a .22 Magnum pistol with a large magazine loaded with the right ammo may be the best option.
