Radian Weapons R0837 Backstrap Fits Sig Sauer P365 X-Macro 5.10" Bronze Aluminum

The Radian Weapons R0837 is a purpose-built backstrap for the Sig Sauer P365 X-Macro, engineered to transform grip control and shooting consistency on this popular compact carry gun. If you shoot a P365 X-Macro 5.10" and want a repeatable, high-contact grip that handles faster follow-ups and tighter groups, this bronze aluminum backstrap delivers the kind of tactile feedback that separates good shooting from solid shooting.

The design philosophy is straightforward: maximize palm contact without sacrificing carry comfort. Deep, aggressive channels run across the grip surface to lock your hand in the same position shot after shot—consistency that translates directly to improved accuracy and faster splits. The integral palm swell acts as a repeatable reference point, letting muscle memory do its job. For everyday carry, the low-profile geometry keeps the gun from printing under concealment and reduces snagging when you draw or holster. This is gear that stays out of your way until you need it.

Installation uses a precision dovetail interface with a spring-loaded retention stud—no screws to loosen or break under recoil and daily handling. The backstrap pairs with Radian's matching magazine well (sold separately) to create a complete grip system, though it functions independently on your P365 X-Macro frame. Bronze aluminum gives you durability with a finish that wears naturally and hides wear better than bare metal.
