The Taurus is the most compact. Other features are appealing, and the Taurus is the only pistol with a changeable backstrap. The sights are basic, the grip treatment is good, and the trigger is manageable.
The Taurus GX4 has nice hidden features, such as a nitride-finished slide and coated internal parts. The pistol is similar to other subcompact pistols and is easily the most compact of the three pistols tested.
