About the new Taurus TX22 Compact pistol

Taurus has unveiled a more compact version of the TX22, the TX22 Compact. It’s small in size but still holds a substantial 13 rounds of .22 LR, which is more than most full-sized .22 pistols hold. It’s built with a polymer frame that includes low-profile ambidextrous controls. The frame has a modern, angular design and an accessory rail that allows for the mounting of a flashlight or laser. The barrel is threaded to attach a suppressor adapter and is level with the slide. The slide features vents and is equipped with front and rear serrations for easy cocking.
