The .22 LR TX22 has been one of the most popular models in Taurus’ lineup, providing an affordable semi-automatic handgun for plinking, training and competition. Based on its popularity, Taurus introduced the 9 mm Luger TX9 series earlier this year. Using the TX architecture yet again, Taurus is adding the 5.7x28 mm and .22 WMR to its chambering options with the new-for-2026 TXM.

The TXM is an optic- and suppressor-ready handgun chambered in 5.7x28 mm and .22 WMR based on the architecture of the TX series.

The TXM is based on the aesthetics of the Taurus’ TX series. They are semi-automatic, striker-fired, polymer-framed handguns with both a firing pin block and a trigger safety. Chambered in either rimfire .22 WMR and the centerfire 5.7x28 mm, the TXM can change between cartridges by switching the slide-and-barrel assembly and magazine.

Barrel length is 4.5 inches or 5 inches for the version that is extended with a 1/2x28 TPI threaded muzzle for both cartridges. The .22 WMR version uses an aluminum slide, while the 5.7 version’s slide is made of steel. This results in a weight of just at 18 ounces for the rimfire version and 24 ounces for the centerfire. Slides are optics ready using the T.O.R.O. system, that allows direct mounting of RMSc footprint optics. Iron sights are a serrated face drift-adjustable rear paired with a front post with a white dot.

The .22 WMR version of the TXM uses an aluminum-alloy slide.

The 5.7x28 mm chambered TXM uses a steel slide.

The interchangeable upper slide assemblies are available from Taurus as standalone products (rimfire for $304 and centerfire for $349) for owners who want to switch cartridges on the same frame. The 5.7x28 mm-chambered TXM uses a flush-fit magazine that holds 23 rounds, while the rims of the .22 WMR version limit the capacity to 15 rounds. Both magazines are available in restricted 10-round capacities. Spare magazines for both retail for $40.

The Taurus TXM uses proprietary magazines that hold 23 rounds of 5.7x28 mm or 15 rounds in .22 WMR.

The TXM is available in seven configurations. Both 5.7 and .22 WMR versions are available with threaded or unthreaded barrels and full capacity or limited-capacity magazines. Models chambered in 5.7x28 mm have an MSRP of $508, while .22 WMR versions retail for $425. They will also sell a TXM combo kit that includes both slide assemblies and one magazine each for $758.
