The Pearce Grip XD Mod 2 Magazine Extension is designed specifically for Springfield Armory XD Mod 2 models chambered in 9mm and .40 S&W. This magazine extension replaces the factory floor plate, adding approximately 1 inch in length and increasing magazine capacity by 2 rounds for 9mm and 1 round for .40 S&W. Crafted with a texture pattern that matches the factory grip, this extension enhances your shooting experience by providing a more secure hold and increased ammo capacity. Please note, this extension is not compatible with the 10-round 9mm magazines or XDM frames, ensuring a perfect fit for your XD Mod 2.
