PSR explores the Nine Lives Defense chassis, a system designed to transform the standard Taurus TX22 pistol into a compact personal defense weapon (PDW). This clamshell setup gives the humble .22 LR pistol the appearance of a mini MP7, complete with a folding brace and plenty of rail space for accessories. To help the gun cycle reliably while suppressed, a heavy metal charging handle is added to the rear of the slide, providing just enough extra weight to keep the mechanical bits happy while looking somewhat tactical.

The installation process is straightforward, involving about seven screws to sandwich the pistol inside its new plastic home. While the chassis is currently made using additive manufacturing—or as the host calls it, "squirted" plastic—it features aluminum rails to ensure things don't snap off during a spirited range session. The only real downside mentioned is that cleaning the gun now requires a bit of minor surgery to remove those seven screws, but that seems like a fair trade-off for the aesthetic upgrade.

During a side-by-side comparison, he demonstrates that adding three points of contact makes a noticeable difference in accuracy. While the unadorned compact version of the pistol tends to jump around like a caffeinated squirrel during rapid fire, the chassis version stays remarkably steady, keeping an entire magazine on target with ease. Ultimately, the project is less about serious home defense and more about having a good time at the range with a setup that "rips" without breaking the bank on ammunition.
