Taurus TXM Lets Shooters Swap Between 5.7x28mm and .22 WMR on One Frame

Taurus has built a single striker-fired pistol, the TXM, that switches between 5.7x28mm and .22 WMR by swapping the upper assembly on one polymer frame, answering customer demand for a magnum TX22 and then some.

Snapshot

The TXM keeps the TX22's grip, trigger and controls but opens up two very different cartridge options on one lower. According to The Firearm Blog, the appeal is practical: 5.7x28mm offers flat-shooting performance at a real cost, while .22 WMR is cheaper to shoot and still useful for training and small game, and the TXM lets an owner run both without buying a second gun or learning new controls.

Key points

• Caliber swap: changing the upper assembly converts the same frame between 5.7x28mm and .22 WMR, which Taurus says is a first for a production pistol.
• Capacity: full-size 5.7x28mm models hold 23 rounds and .22 WMR models hold 15, both generous for pistol-caliber rimfire and bottleneck options.
• Build: single-action-only trigger, stainless slide with black hard-anodized finish, polymer frame, threaded barrel standard, and T.O.R.O. optics compatibility using the Shield RMSc footprint.
• Pricing and options: the 5.7 TB runs $507.99, the .22 WMR TB is $424.99, and the combo kit with both uppers and two 10-round magazines is $756.99.

Quick take

The reviewer at The Firearm Blog says the TX22-based ergonomics are a strong starting point, since the TX22 already has a reputation as one of the better rimfire pistols around. The writer says they like the dual-caliber concept and would lean toward the combo kit if the upper swap is as fast as Taurus claims, though they note running one gun in two calibers instead of two separate pistols may not suit everyone.
