Taurus TXM Pistol Holds 23 Rounds of 5.7x28mm and Swaps to .22 WMR

Taurus posted product pages on November 10, 2026 for the TXM, a full-size pistol that switches between 5.7x28mm and .22 WMR, with the 5.7x28mm model at an MSRP of $507.99 on its product page. American Rifleman covered the new-for-2026 pistol the same day.

Taurus, based in Bainbridge, Georgia, calls the TXM the first pistol built to switch between the two cartridges. You change calibers in seconds by swapping the upper assembly, the slide and barrel, on one frame. The grip and trigger stay the same, and the pistol is built on the ergonomics of the Taurus TX 22.

The 5.7x28mm upper takes a magazine of 23 rounds, and the .22 WMR upper takes 15. Two 23-round magazines ship with the 5-inch 5.7 TB model.

The combo model has an MSRP of $756.99. It includes both uppers, a 4.5-inch barrel and two 10-round magazines. Taurus lists the full-size TXM with a 4.5 or 5.0 inch barrel in 5.7x28mm, in .22 WMR, or as the combo, and American Rifleman counts seven configurations in all. Taurus’s site shows six product pages, the sixth a threaded-barrel combo at $757.99 that ships with one 23-round and one 15-round magazine. The .22 WMR models list at $424.99, the 4.5-inch version with two 10-round magazines and the 5-inch threaded version with two 15-round magazines. American Rifleman rounds the prices to $508, $425 and $758 and says spare upper assemblies sell for $304 in rimfire and $349 in 5.7x28mm, with spare magazines at $40.

The frame is polymer and the barrel is alloy steel. On the .22 WMR upper the slide is aluminum alloy, and on the 5.7x28mm upper it is steel, American Rifleman says. Taurus’s own spec sheets list the slide material as stainless steel on every TXM page, the .22 WMR models included, with a hard-anodized black finish, and put the threaded .22 WMR model at 17.85 ounces against 24.4 for the threaded 5.7x28mm. Action is single action only. A trigger safety works with a striker block and a firing pin block.

Optics mount directly through the T.O.R.O. System, which uses the RMSC pattern. American Rifleman says the seven configurations include threaded and unthreaded barrels. It gives the 5-inch version a 1/2x28 TPI threaded muzzle for both cartridges, TPI being threads per inch, the pitch that decides which suppressors will mount. Sights are a fixed front post with a white dot and a drift-adjustable serrated rear.

None of the six product pages posted on November 10, 2026 lists a ship date, and buyers can find dealers through the Taurus dealer locator.
