The XD® Mod.2™ 9mm Threaded Service Model is perfectly proportioned for silenced use. It’s big enough to host a suppressor, yet compact enough to keep overall handling characteristics just right. The ½”x28 threading accepts 9mm and larger silencers – out of the box. A thread protector cap is included to protect barrel threading when shooting unsuppressed. The threaded model ships with a flat dark earth frame and black Melonite® slide.
