Backstrap + Magwell Set for SIG SAUER P365 XMACRO Radian®

The Backstrap + Magwell set by Radian is designed specifically for the SIG SAUER P365 XMACRO to improve grip consistency and magazine insertion without compromising concealability. The backstrap enhances hand contact and grip stability, while the low-profile magwell guides the magazine during reloads. Both components integrate cleanly into the frame and are secured using Radian’s ANGLE-LOK spring pin system.

Design and Installation

Both the backstrap and magwell install via a precisely machined dovetail interface and are retained by the patented ANGLE-LOK spring pin. This mounting method eliminates the need for screws or threaded fasteners, reducing the risk of loosening or hardware failure. Installation is straightforward and results in a rigid, flush fit with the grip module.

Grip Ergonomics

The backstrap features pronounced texturing and contouring to increase contact between the shooter’s hand and the frame. The texture improves grip security without creating sharp edges or discomfort during extended shooting sessions. A subtle palm swell provides a consistent reference point for repeatable hand placement, helping stabilize the pistol during recoil.

Magwell Function

The integrated magwell improves magazine alignment during reloads by guiding the magazine into the grip. Raised internal surfaces assist with both tactical and administrative reloads while maintaining a low external profile. The design avoids excessive bulk, minimizing the risk of snagging during holstering or drawing.

Compatibility and Carry

The set is fully compatible with OEM SIG SAUER P365 XMACRO magazines, including factory base plates and extensions. The slim profile helps limit printing during concealed carry, making the system suitable for everyday use. Installation and removal can be performed without specialized tools, supporting practical deployment.

Practical Effect on Handling

Improved grip geometry and increased hand contact contribute to better recoil control and more consistent shot placement. Faster, more reliable magazine insertion reduces downtime during reloads. Together, these changes enhance overall handling without altering the core characteristics of the pistol.

Construction and Durability

The dovetail interface and ANGLE-LOK retention system provide a secure, repeatable fit with minimal play. Precision machining ensures consistent alignment with the frame. The design balances aggressive grip enhancement with long-term comfort and durability under regular use.
