The Laserguard is designed to fit both lines in all sizes and calibers. Featuring Instinctive Activation, the laser sight immediately springs to life when held in a normal firing grip. Attaching firmly to the trigger guard and balanced against the accessory rail notch, the LG-448 can be zeroed by the user to their individual firearm (both windage and elevation) and has been rigorously tested to hold zero under the most demanding field conditions. *Fits Springfield Armory XD and XDM Models. **Except Tactical 5" and Service 4" XD Gen1 with single rail notch.
