The TX22 ART works with all Taurus TX22 models and generations. It installs as a drop-in replacement for the factory disconnector, keeping the original trigger and remaining fire control components in place. This Taurus TX22 disconnector replacement is intended for users who need to replace the stock disconnector without changing the rest of the fire control system. As one of the internal TX22 parts, the disconnector affects reset and sear interaction, making proper fit important.
