The Radian Weapons P365 X-Macro Backstrap (brand part number R0837) is a machined aluminum grip upgrade for the SIG Sauer P365 X-Macro, finished in bronze for a distinctive look over the factory polymer grip. Radian cuts aggressive, deep channels into the backstrap to maximize contact surface and give shooters a more secure hold, while a palm swell shape delivers a repeatable connection point for better control of the pistol under recoil. The low-profile design keeps the grip footprint tight against the frame, limiting printing under concealment and reducing snag points during a draw or holster. It’s a straightforward, tool-free upgrade for X-Macro owners who want a more dialed-in grip.
