Taurus TXM lets one pistol swap between 5.7x28mm and .22 WMR

November 10, 2026

Taurus has rolled out the TXM, a polymer-frame striker-fired pistol that switches between .22 WMR and 5.7x28mm by swapping the upper assembly on one frame.

Snapshot

Built on the well-liked TX22's ergonomics, the TXM lets owners run two very different cartridges through the same grip, trigger and controls. TheFirearmBlog reports Taurus designed it after customer requests for a magnum TX22, then expanded the concept into a true dual-caliber platform rather than a single new chambering.

Key points

  • Caliber swap: One frame accepts either a 5.7x28mm or .22 WMR upper, so there's no second gun or manual of arms to learn.
  • Capacity: Full-size models hold 23 rounds in 5.7x28mm or 15 rounds in .22 WMR; the combo kit ships with two 10-round magazines.
  • Pricing: The 5-inch TXM 5.7 TB runs $507.99, the 5-inch TXM 22WMR TB is $424.99, and the 4.5-inch combo kit with both uppers lists at $756.99.
  • Features: Every version comes optics-ready via Taurus's T.O.R.O. system (Shield RMSc footprint), with a threaded barrel, fixed white-dot front sight, drift-adjustable rear, and a stainless slide over a polymer frame.

Quick take

The appeal here is economics as much as novelty: 5.7x28mm is fun but pricey to shoot, and .22 WMR gives you a cheaper way to train on the same gun. TheFirearmBlog's writer says the combo kit would be the pick if the upper swap is as fast as advertised, and that's a reasonable take if you want one pistol that covers both range days and ammo budgets.
