.22 Magnum Pistol: What’s Available In Semi-Auto?

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.

What Are The Best .22 Magnum Pistols?:

A semi-automatic .22 Magnum pistol … cue crickets chirping. Popular as the souped-up rimfire cartridge has proven over the past 60 odd years it’s never really conquered the pistol market. Revolvers, those chamber in what’s 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.

What’s the deal? There’s 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 incorrectly—that is, hitch a rim behind another rim—and you’re managing a failure to feed. Jam-o-matics aren’t a load of fun, even if they deliver more punch to their destination.

If that isn’t enough, the .22 Magnum is a high-pressure cartridge that doesn’t 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 issue—cost.

22 Mag Winchester

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 they’re ambitious, maybe they’ll roll the dice on a .22 Magnum revolver. Grimace if you must, but their calculus isn’t 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, they’re ponying up nearer to a quarter per pop. That adds up—particularly for plinking and pleasure shooting. Given these factors, it’s almost a wasteland when it comes to .22 Magnum pistols … 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 isn’t exactly awash in options. So, as your mother most likely told you on more than one occasion, beggars can’t be choosers.

.22 Magnum Pistol Options:

Rock Island Armory XT

  • Traditional 1911 feel and look

Magazine: 14 Rounds

Rock-Island-XT-22-magnum-pistol

With a fraction of the fanfare it deserved, Rock Island launched its XT line a little over a year ago. Yet, the pistol deserves credit, it delivers on all accounts—affordability, 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 that’s part of the pistol’s 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.

The XT has a real sporty feel to it, so it's easy for us to imagine that it would do well in a competitive setting. 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 pistol’s configuration lends it to self-defense, though, the caliber might not be anyone's first choice. And even though it’s light, the XT is too large to make it a backup option.


Kel-Tec PMR-30

Pros:

  • Highest capacity
  • Most affordable (can be found new for about $350 at time of writing)

Cons:

  • Some users report reliability issues when the mag is loaded by hand rather than with a speed loader

Kel-Tec PMR-30
Caliber: .22 Magnum
Barrel Length: 4.3 inches
Overall Length: 7.9 inches
Weight: 14 ounces
Magazine: 30-round
MSRP: $495

Kel Tech

When the Kel-Tec labs unleashed this Frankenstein’s monster around a decade ago, it was met with—to be honest—furrowed brows. What exactly was the angle of the plasticity, futuristic-looking .22 Magnum pistol? Not easily categorized, the new-wave heater nonetheless shouldered its way on the market, if for no other reason than sheer, unadulterated firepower. There aren’t many problems that can’t be solved with 30 rounds on tap.

Yes, for those unfamiliar with the PMR-30, that’s its hook—capacity. Which, when you put your mind to it, makes this fairly difficult to classify pistol quite useful for many applications. Backwoods insurance policy, rucksack’s best friend, inconspicuous truck gun—in essence, Jack-of-all-trades. Perhaps its most agreed-upon role is as a bug-out bag pistol.

Next to firepower, the PMR-30’s light weight is its greatest asset. Even fully juiced, it doesn’t weigh much more than a centerfire duty pistol. And for all its idiosyncrasies, the pistol is easy and comfortable to run, even delightful. It fits the hand well, boasts a snappy trigger and, thanks to Hi-Viz sights, is relatively quick on target. Overall, it offers a lot for someone in the market for something a bit different, but functional.


Excel Arms MP-22 Accelerator

Pros:

  • Best potential ballistics thanks to its 8.5-inch barrel

Cons:

  • No longer in production
  • Bulky, arguably outdated design

Excel Accelerator
Caliber: .22 Magnum
Barrel Length: 8.5 inches
Overall Length: 12.88 inches
Weight: 54 ounces
Magazine: 9-round
MSRP: N/A

Excel

No, ultra-accurate .22 Magnum pistols haven’t gone the way of the dodo. Quietly, niche manufacturer Excel has continued this once popular-vein of rimfire handgun with the Accelerator—a true mammoth of this class. No seriously, it’s a big piece—54 ounces!

Much of this is thanks to the heart of the Browning Buckmark-esque pistol, an 8-inch stainless-steel bull barrel that dang near needs a blow torch to heat up. Surprisingly enough, even with the sheer amount of firetube, the gun balances well in the hand and doesn’t prove front-heavy. Partly, this is due to plenty of frame reward and how Excel positions the grip, with a fair amount of slide hovering over the hand.

Excel offers some interesting design points on the Accelerator, from a Weaver-style rail on the slide to magazines with an assisted loading system. But the one that sticks out like a goiter is the charging handle. Don’t laugh until you try it. While many might write it off a garish, it’s plum handy and fast if you’re running an optic up top.

While it appears that Excel Arms is now out of business, the Accelerator MP-22 is still available on the second hand market for reasonable prices.


Walther WMP

Pros:

  • Ready for a modern pistol red dot and weapon light out of the box
  • Ambidextrous

Cons:

  • Newest model on this list, so has least amount of real-world use and is yet to establish a reputation.

Walther WMP
Caliber: .22 Magnum
Barrel Length: 4.5 inches
Overall Length: 8.2 inches
Weight: 27.8 ounces
Magazine: 15-round
MSRP: $549

Walther WMP

New for 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.
