Abstract: A ammunition magazine for a hand-held firearm or weapon, having a photo-luminescent (i.e. glow-in-the-dark) base portion (e.g. base plate) that emits visible illumination and enables the firearm user, in darkness, to quickly access the ammunition magazine, accurately determine its spatial orientation, properly insert (i.e. load) the magazine into the firearm in a correct manner, retrieve the spent magazine, remove (i.e. unload) it from the firearm, and then reload another loaded magazine, quickly without error or reloading errors or delays.
