Description
The Radian TRU-17 is a direct-fit base pad replacement for SIG Sauer P365 X-Macro magazines, sold as a two-pack. It is designed to work as part of a system alongside the Radian Macro backstrap and magazine well, though it functions on its own as well.
The added weight at the base of the magazine serves a practical purpose: a heavier bottom end encourages spent magazines to fall free cleanly under their own momentum rather than hanging up on the grip, which matters most during fast reloads under stress. The increased grip surface at the base also gives your support hand a more secure purchase when indexing magazines from a pouch, and provides enough leverage to break loose a magazine that has become stuck in the well.
The TRU-17 name reflects the other half of what this pad does. Loading a double-stack magazine to its full capacity is notoriously stiff against spring pressure, and the geometry of this base pad is shaped to give your thumb better mechanical advantage when pressing that final round home. The result is a 17-round magazine you can actually top off without tools or a loader, though a loader remains an option.
The pad is machined from aluminum and finished in black. Fit is specific to the P365 X-Macro magazine — it is not a universal base pad and should not be assumed compatible with other P365 variants that use a different magazine footprint.
