The Radian P365-XMACRO Backstrap and Magazine Well were designed in tandem to provide users with a rock-solid and enhanced grip on one of the most popular everyday-carry firearms on the market today – The Sig Sauer P365. The P365-XMACRO Backstrap features aggressive and deep channels which maximize contact surface and enhance overall grip, all while remaining forgiving on the hands. The palm swell allows for a repeatable connection resulting in more control of the firearm. This consistency leads to improved performance/accuracy and quicker follow-up shots.
