Taurus TXM: One Pistol That Swaps 5.7x28mm and .22 WMR

Last updated November 2026 · By Nick Hall, who reviewed the Taurus TX22 and covers new pistol launches for USA Gun Shop

Quick take: Taurus just launched the TXM, a striker-fired pistol that runs 5.7x28mm or .22 WMR on the same frame. The 5.7 version is $507.99, the .22 WMR is $424.99, and a combo with both uppers is $756.99.

• What it is: A full-size polymer pistol built on TX22 ergonomics with swappable 5.7x28mm and .22 WMR uppers.
• Price: MSRP is $507.99 for the 5.7, $424.99 for the .22 WMR and $756.99 for the two-caliber combo.
• Where: Taurus dealers, with all three models posted on taurususa.com on November 10, 2026.
• Why it matters: It is a sub-$510 5.7 host that can also burn cheaper rimfire magnum on the same grip and trigger.

“Changed in seconds” is the line Taurus leads with. The manual tells the fuller story, and it is the one worth reading before you pick which of the three boxes to buy.

What Taurus Actually Launched

Taurus posted three TXM models on November 10. The TXM 5.7 (item 1-TXM5741-10) lists at $507.99. The TXM .22 WMR (1-TXM22M41-10) is $424.99. The TXM 5.7/22WMR combo (1-TXM22M5741-10) gives you one frame and both uppers for $756.99.

Taurus sums it up as “Two Calibers. One Pistol.” Its product copy goes further and calls the TXM “the first pistol ever built to switch between 5.7x28mm and .22 WMR,” so that is the maker’s claim, and the pitch for the whole line.

The specs are shared across all three. It is a single-action striker-fired gun with a polymer frame, a 4.5 inch threaded barrel, a TORO optic cut for RMSC-pattern red dots, a fixed white dot front sight and a drift-adjustable serrated rear. It is 8.1 inches long, 5.6 inches tall and 1.25 inches wide. Safeties are a striker block, a trigger safety and a firing pin block.

Weight is where the two calibers part ways. The 5.7 weighs 23.85 ounces and the .22 WMR 17.55 ounces. Taurus’s manual explains most of that gap: the .22 WMR slide is hard anodized aluminum, while the 5.7 slide is nitrocarburized stainless steel. Twist rates differ too, 1:9 for the 5.7 and 1:10 for the .22 WMR.

How the TXM Caliber Swap Actually Works

Taurus’s product page says the caliber is “changed in seconds by swapping the upper assembly.” The TXM instruction manual spells out what that upper is: “The components that differ between the .22 WMR and 5.7x28mm versions are the slide, barrel, recoil spring assembly, and magazine.”

So the frame stays put. Grip, trigger, fire control parts and the magazine release all stay on the gun, which is why Taurus can say both versions “share the same frame.” Everything that touches the cartridge comes off.

No tools. The takedown in the manual goes like this: clear the gun, point it somewhere safe and pull the trigger, draw the slide back about half an inch, pull the disassembly latch down, then push the slide forward and lift it off. Pop the recoil spring assembly off the barrel, lift the barrel out, and the old caliber is in your hand. Reassembly runs in reverse, and Taurus wants you to cycle the slide several times with the magazine out to confirm everything is seated.

And here’s the kicker for anyone running a red dot. The optic screws to the slide, and the slide is one of the parts that changes, so your dot leaves with the caliber you took off. A combo owner either buys a second RMSC-footprint dot or moves one between slides and re-zeros every time. With a cartridge that shoots as flat as 5.7, that is an annoyance I would rather pay to skip.

The magazines are caliber-specific, and the manual has a separate takedown for each. The .22 WMR magazine has a loading button on the follower, the 5.7 does not, and they do not cross over.

The $507.99 5.7x28mm Math

A 5.7 pistol for $507.99 is a real number. Ruger currently prints $549 MSRP on its standard Ruger-5.7, so the TXM 5.7 comes in $41.01 under it before either one hits a dealer counter. PSA’s Rock still owns the very bottom of the market when it is on sale, and the FN that started all this lives in a different price bracket entirely.

The combo is where the TXM gets interesting. Two complete guns would cost $932.98 at MSRP, and the combo is $756.99, a $175.99 saving for the price of owning one serialized frame instead of two. Put another way, the .22 WMR upper and its magazine cost you $249 over the 5.7 alone.

That math only works if you will actually shoot the rimfire half. If you want a cheaper trainer that points exactly like your 5.7 and keeps the same trigger under your finger, the combo makes sense on day one, and if you already own a Taurus TX22 the grip will feel familiar because the TXM is built on TX22 ergonomics.

The manual also says a .22 WMR owner can pick up a 5.7x28mm conversion kit from ShopTaurus.com “and vice versa,” so buying one caliber now does not lock you out of the other later.

The Fine Print on the Launch Models

Capacity is the catch. All three launch models ship with 10-round magazines: two in each single-caliber box, one per caliber in the combo. Taurus’s copy and manual list 23-round capacity for the 5.7 and 15 rounds for the .22 WMR, but the three product pages that went live on November 10 are the 10-round versions. Check what your dealer actually has before you assume 23 rounds come in the box.

Taurus also puts weight limits in writing. The manual says to keep optics at or under 1 ounce, keep muzzle devices such as suppressors or compensators at or under 5 ounces, and it recommends ammunition of 40 grains or heavier whenever either one is installed. Check the box before you thread a can onto the .22 WMR upper.

Two smaller notes from the manual. There is no magazine disconnect, so the TXM will fire with the magazine out, and the magazine release is reversible for left-handed shooters. Taurus also wants the chamber cleaned every 500 rounds, with a .30 caliber brass brush for the lacquer that 5.7 ammo leaves behind.

Which Taurus TXM Box to Buy

Taurus framed the launch as a customer request. “Our customers made it clear they wanted a magnum version, and we saw an opportunity to go even further,” said Michael Marotte, Marketing Director of Taurus USA, in the launch release.

If you want a 5.7 and nothing else, the $507.99 TXM 5.7 is the box, and you can add the rimfire upper later. If you want a cheap magnum rimfire pistol for plinking and small game, the $424.99 .22 WMR does the job and leaves the door open to 5.7 down the road. If you already know you will shoot both, buy the combo, put a dot on the 5.7 slide, and accept that the .22 WMR upper is the one living on iron sights until you buy a second optic, because that $175.99 saving over two separate guns is the best price Taurus offers on this platform right now.

One frame. Two calibers. The value is real, as long as you count the second dot.
