LaserMax has added two models to their ever-expanding line of laser sighting devices. The new LaserMax sights are custom-engineered for use in Springfield Armory XD 4-inch and 5-inch pistols. LaserMax's internal sight installs in a minute inside the firearm, replacing the recoil spring assembly. The LMS-4XD40, LMS-4XD9/357 and LMS-5XD feature guaranteed precision alignment, which requires no adjustments and will not change over time. All LaserMax sights feature a pulsing red-orange 635 nM beam allowing fast target acquisition and increased accuracy, particularly in low-light. The LaserMax internal guide-rod sight is compatible with all tactical lights, grips, safeties and holsters.
