Key Takeaways
- →Two calibers, one frame: the TXM comes in 5.7x28mm and .22 WMR, and both versions share a frame. Changing calibers means swapping the slide, barrel, recoil spring, and magazine.
- →Capacity: 23+1 in 5.7x28mm and 15+1 in .22 WMR from flush-fit magazines, with 10-round versions of both.
- →Price: $424.99 MSRP for the .22 WMR TB, $507.99 for the 5.7 TB, and $757.99 for the threaded combo kit with both uppers.
- →Optics and suppressors: a T.O.R.O. slide takes RMSc-footprint red dots with no plate, and TB models have a 5-inch barrel threaded 1/2x28.
- →Not a rechambered TX22: the TXM runs a delayed-blowback action, and the 5.7 model has a steel slide, weighing 24.4 oz against 17.85 oz for the .22 WMR.
What the Taurus TXM Is
The Taurus TXM is a magnum version of the TX22: a full-size, polymer-frame, striker-fired pistol chambered in 5.7x28mm or .22 WMR, announced on November 10, 2026. The M stands for magnum, and Taurus built it because TX22 owners kept asking for one. Taurus calls it the first pistol built to switch between 5.7x28mm and .22 WMR on one frame.
Both calibers are built on TX22 ergonomics and run the same single-action striker trigger. The frame is common to both versions, and the Taurus manual lists only four parts that change between calibers: the slide, the barrel, the recoil spring assembly, and the magazine. You can buy one caliber now and add the other upper later, or buy the combo kit with both.
The TX22 it grows out of is one of the most popular pistols in Taurus's lineup, and our TX22 upgrade guide covers that gun. The TXM is a separate pistol with its own magazines and action, so treat TX22 parts as non-interchangeable unless a maker says otherwise.
Taurus TXM Specs and Configurations
Taurus sells the TXM in both calibers with threaded and unthreaded barrels, full-capacity and 10-round magazines, and as a two-caliber combo kit. The TB (threaded barrel) models below are the full-capacity versions with a 5-inch barrel threaded 1/2x28; the unthreaded models use a 4.5-inch barrel.

Taurus MSRPs as of November 2026: the .22 WMR TB is $424.99, the 5.7 TB is $507.99, and the threaded combo kit is $757.99. Taurus also sells each caliber's upper and spare magazines separately.
The combo kit is the cheaper way to get both calibers. It costs $333 more than the .22 WMR TB alone and ships with one magazine per caliber.
Buy the Taurus TXM
The 5.7 TB is the configuration to buy if the pistol has any defensive role: 23+1 of centerfire 5.7x28mm, a threaded barrel, and an optic cut for $507.99 MSRP. The .22 WMR TB at $424.99 is the cheaper way into the platform, and it can take the 5.7 upper later. The threaded combo kit at $757.99 is the pick if you want both from the start.

We cover new Taurus pistols and 5.7x28mm launches as they are announced, with full specs and pricing.
Delayed Blowback, Steel Slide, and Trigger
The TXM is not a straight blowback pistol like the .22 LR TX22. Both calibers use a delayed-blowback action: a hinged vane in the frame sits in a pocket under the barrel, and its angled face briefly holds the barrel back under recoil until pressure drops, then folds down and lets the slide run. 5.7x28mm and .22 WMR both run at higher chamber pressure than .22 LR, which is what the delay is for.
The 5.7 version gets a steel slide and the .22 WMR version an aluminum-alloy slide; the 5.7 TB weighs 24.4 oz unloaded against 17.85 oz for the .22 WMR TB. Athlon Outdoors measured the trigger at about 0.14 inch of take-up to a firm wall and a break at about 4 pounds. The magazine release can be reversed for left-handed shooters; the slide stop is on the left side only.
The sight dovetail and front sight mount follow the Glock pattern, so aftermarket Glock-pattern sights drop in. The grip is large: the long 5.7 and .22 WMR cartridges need a long front-to-back grip, and its circumference is close to a 1911's.
Red Dots and Suppressors on the TXM
Every TXM takes an RMSc-footprint red dot directly on the slide through Taurus's T.O.R.O. cut, with no adapter plate. That footprint fits the Shield RMSc and the micro red dots built to the same pattern; larger footprints need an aftermarket adapter plate. Our pistol red dot guide sorts those optics by footprint, and how to zero a pistol red dot covers getting one on target.
The TB models are threaded 1/2x28, the most common pitch for .22-caliber cans. Check the suppressor's rating before mounting: many rimfire cans are rated for .22 WMR, but 5.7x28mm is a centerfire cartridge, so it needs a can the maker rates for 5.7x28mm. Our 5.7x28mm suppressor guide lists cans rated for the round.
RMSc-Footprint Red Dots
Osight K (RMSc 6 MOA Open)
- 6 MOA red dot
- Open emitter, RMSc footprint
Shield RMSc 4 MOA (Glass Edition)
- 4 MOA red dot
- Shield RMSc footprint (defines the standard)
Osight SE Enclosed (6 MOA Red)
- 6 MOA red dot
- Enclosed emitter, RMSc footprint
Osight SE Enclosed (2 MOA + 32 MOA Red MRS)
- 2 MOA dot + 32 MOA circle MRS
- Enclosed emitter, RMSc footprint
Swampfox Sentinel II
- 3 MOA red dot (or green)

5.7x28mm or .22 WMR: Which TXM to Buy
Buy the 5.7x28mm TXM if the gun will ever be used for defense, and the .22 WMR TXM if it is mainly for range time, pests, and small game. In Athlon Outdoors' hands-on testing the two cartridges felt similar in recoil, but 5.7x28mm is centerfire, and centerfire primers are more reliable than rimfire ignition. Taurus pitches the .22 WMR for training, plinking, and small game and the 5.7 for speed and reach.
The pairing is the point of the platform. .22 WMR costs less per round than 5.7x28mm and shoots through the same grip, trigger, and red dot, so the rimfire upper works as a trainer for the centerfire one. Our 5.7x28mm ammo guide ranks defense and range loads for the centerfire side.
How the TXM Compares to Other 5.7 Pistols
At $507.99 MSRP with 23 rounds, a threaded barrel, and a direct RMSc cut, the TXM 5.7 TB lands in the value tier of 5.7x28mm pistols with the Ruger-57, PSA 5.7 Rock, and Tisas PX-5.7. Its distinctions are the .22 WMR conversion, which Taurus says no other pistol offers, and its 24.4 oz weight. Our best 5.7x28mm pistols guide ranks the full field.
The Ruger-57 is the established alternative with a long track record. It ships with 20-round magazines, an adjustable rear sight, and a non-threaded barrel; Ruger sells a 1/2x28 threaded barrel kit separately. To see the TXM with an optic and light, open it in the pistol configurator.

- −Optic mounting needs the Ruger adapter plate; there is no direct RMR/507C slide cut
