Taurus TXM: One Pistol, Two Calibers - 5.7x28mm & .22 WMR

Taurus customers have been asking for a magnum version of the TX22 for a while. Taurus has answered with the TXM, and it went a step further than people asked for. The new polymer-frame, striker-fired pistol comes in both .22 WMR and 5.7x28mm, and Taurus calls it the first pistol built to switch between the two by swapping the upper assembly on a single frame.

The logic is easy to follow. 5.7x28mm is flat-shooting and a lot of fun, but it is not cheap to feed. I recently shot my friend’s FN 5.7, but the price for the ammo was considerable. .22 WMR costs less, still has some punch, and works well for training, plinking and small game. With the TXM you can run both on the same grip, the same trigger and the same controls, so there is no second gun to buy (some may find that a disadvantage) and no second manual of arms to learn. I like the idea a lot, and if the upper swap is as quick as Taurus suggests, the combo kit is the version I would pick.

The frame is built on TX22 ergonomics, which is a good starting point. The TX22 earned its reputation as one of the best rimfire pistols on the market, and the TXM keeps the feel of it, so a TX22 owner should feel at home straight away.

Capacity is generous, almost rifle-like. The 5.7x28mm models hold 23 rounds and the .22 WMR models 15, in the full-capacity versions. Every TXM is optics-ready through Taurus's T.O.R.O. system, which uses the Shield RMSc footprint, and a threaded barrel comes standard. Sights are a fixed white-dot front and a drift-adjustable serrated rear. The action is single-action only, with a trigger safety, striker block and firing pin block. The slide is stainless steel with a hard-anodized black finish, and the frame is polymer.

The 5-inch TXM 5.7 TB (Threaded Barrel, and the one to get) is item 1-TXM5751-TH with an MSRP of $507.99, and the 5-inch TXM 22WMR TB is 1-TXM22M51-TH at $424.99. The combo kit, 1-TXM22M5741-10, has a 4.5-inch barrel and comes with both uppers and two 10-round magazines at $756.99.

    What's up with the roll pin in the slide forward of the chamber?

      My bet would be it holds in a hardened steel piece that serves as the barrel hood lockup lug and the rest of the slide is cheaper/softer metal.

    I remember when I started acquiring firearms, I wanted to keep calibers to a minimum. I guess 10 calibers is the new minimum.

      I've like 7 cartridges total. This gun would add 2 borderline useless cartridges. Add a 410 underbarrel and you'd get the useless trifecta. Jokes aside, 22 magnum isn't a dumb alternative to 5.7 in the same gun. Sure, 22 has worse performance but is way more available and cheaper than 5.7 while being similar for plinking/training purposes.
