Claim:
An ammunition magazine with an improved base locking, comprising a hollow magazine body, a follower, a spring and a magazine base; where said magazine body is equipped with track guides which correspond with grooves on said magazine base that is slid onto; where said follower is pressed by said spring which pushes against the magazine base with its first turn; where said spring follows an inner shape of the magazine body with its first turn, while the second turn is embodied with a smaller cross-section so that a catch could be placed inside the follower, while other turns of the spring follow an inner geometry of the follower in such a way that the whole spring can be compressed into the follower; wherein: the magazine base has the catch with a slanting side which protrudes into the space of the magazine body, and a hole embodied through the magazine base on the other side of the catch; the magazine body has a slit that allows the catch to pass unobstructed into the inside of the magazine body in the process of attaching the magazine base onto the magazine body, and where the catch catches a detent spot on the first turn of the spring in a way that said detent spot is locked between the catch and the magazine body in the space above the hole.
