There were several firearms that used a magazine that attached at the side of the weapon. One of them was the British STEN gun. Run a Google image search for sten, and see if that is what you are looking for. BTW, that was a simply made submachinegun.
Additionally, there was the MP-18 (which originally used Luger magazines, and was later refitted), MP-28, and Japanese Type 100, which may also be what you're looking for.
