Radian Weapons R0878 Backstrap + Magwell SIG Sauer P365 X-Macro 9mm Aluminum Gray

The Radian Weapons Backstrap + Magwell is a precision-machined aftermarket grip accessory designed specifically for the SIG Sauer P365 X-Macro. Made in the USA from aluminum finished in gray, it replaces the factory backstrap and adds an integrated flared magwell that guides 9mm Luger magazines into the pistol during high-pressure reloads.

Designed as a direct-fit upgrade, the R0878 installs in place of the standard P365 X-Macro backstrap and reshapes the bottom of the grip with a generous magazine flare. The integrated magwell geometry reduces fumble time on defensive and competition reloads, while the rigid aluminum construction holds up to repeated draw and re-holster cycles without shifting under recoil.

Whether you are running a P365 X-Macro for everyday carry or competition, this backstrap and magwell combo gives the compact 9mm pistol a more positive grip interface and noticeably faster magazine swaps. The drop-in installation requires no permanent modification to the host pistol.
