Radian Weapons RADN H0014 Backstrap & Magwell for Sig P365 XMacro

The Radian Weapons backstrap and magwell combo for the Sig P365 XMacro transforms the ergonomics of one of today's most popular everyday-carry pistols. If you're looking to improve your grip security, control, and reloading consistency on your P365 XMacro, this two-piece upgrade addresses the real friction points that matter in defensive shooting and range work. The backstrap and magwell are engineered as a matched set, each component designed to work in concert for a more cohesive, confident shooting experience.

The backstrap features aggressive, deeply channeled grip surfaces that maximize contact between your hand and the frame. Rather than a smooth surface, these channels provide real purchase without punishing your palm during extended shooting sessions. The palm swell promotes a repeatable hand position, which directly translates to better control and faster follow-up shots—critical whether you're training at the range or carrying for personal defense.

The magwell keeps your fingers positioned high on the grip during reloads and maintains flared feed walls designed to handle magazine insertions reliably, even under stress. The rear of the magwell is heavily rounded to eliminate sharp edges that can bite into your palm or print under concealed-carry clothing. This combo maintains full compatibility with all OEM P365 XMacro magazine base pads, so you're not locked into proprietary magazines. Installation uses Radian's patent-pending screwless design—a precision dovetail interface with a spring-loaded retention stud that secures everything without tools or permanent modification.
