Radian Weapons Sig Sauer P365 X-Macro Backstrap Magwell

Radian designed this backstrap and magwell together for the Sig Sauer P365 X-Macro grip module. The backstrap has deep, aggressive channels and a palm swell for a consistent, locked in hold, and the magwell adds a contact point at the bottom of the grip while its feed walls guide the magazine home on reloads.

The profile stays low to limit printing and snagging when you carry. Both parts lock on with a machined dovetail and a spring loaded retention stud, no screws. The magwell works with factory X-Macro magazines and their base plates. Aircraft grade aluminum, black.
