Abstract: Use of this invention enables a commercially available flashlight to be mounted on or in the forward end of a firearm's magazine, thereby configuring a source of illumination in precise alignment with the bore of the gun. In contrast to prior-art devices, the inventive approach requires no modification to the gun in general or magazine in particular, and may consume the space taken by a single shell, allowing the remainder of the magazine to hold shells, as is typical. The preferred embodiment permits certain types of barreled flashlights, such as the Maglight®, Smith & Wesson® or Dorcy® having a diameter on the order of {fraction (7/10)} inch to be mounted on or into the forward end of the magazine through the use of an adapter base module. To position the non-illuminating end of the flashlight in alignment relative to the spring present in the magazine, an optional spring guide in used.
