The TX22 Gen1 Pic Rear Sight is a clever little hack that turns a factory rear sight dovetail into a Picatinny rail, giving Taurus TX22 owners a quick way to mount optics or backup sights without milling the slide. By swapping out the stock sight for a printed rail section, users gain modularity on a pistol that was never designed for it, and the note about PA6-CF versus PLA+ is a reminder that even small parts have to survive recoil and holster wear. What looks like a niche upgrade is actually a quiet statement about how far desktop manufacturing has come: a $0.30 piece of filament can now do what used to require a gunsmith or a new slide.

For the 2A community this matters because it lowers the barrier between “I own a gun” and “I can adapt that gun to my needs.” The TX22 is already one of the most affordable .22 pistols on the market; pairing it with a printable rail means new shooters, instructors, and competitors can experiment with red-dots or suppressor-height sights without spending hundreds on aftermarket slides. It also keeps the original firearm intact—if the printed part fails or laws change, the stock sight goes right back in. That reversibility is quietly powerful in an era when regulators eye every modification as a potential problem.

Beyond the TX22 itself, the part is another data point in the growing library of printable firearm accessories that emphasize function over flash. It doesn’t replace a frame or a receiver; it simply solves an interface problem, and that narrow focus makes it harder to dismiss as some fringe experiment. As more shooters adopt these small, targeted upgrades, the line between what’s “factory” and what’s “user-configured” keeps shifting, and that shift is ultimately about preserving choice in how we equip the tools we already own.
