The XD Mod.4 is the latest in the proven XD platform's lineage, enhancing its reputation for reliability with thoughtful upgrades for today's shooters. It includes a factory-milled slide optimized for industry-leading optics, deeper front and rear serrations for easier manipulation, and a textured frame for better control. The passive grip safety, tactile loaded chamber indicator, and striker-status indicators work together to improve security, while the redesigned flat-face trigger offers a consistent pull and smooth break.
