There are a few threads around here about the British Army replacing the Sten gun with the Australian Owen gun. Usually it's pointed out that the Owen is more reliable and robust than the Sten while the Sten is cheaper and easier to make than the Owen. A while ago though I read a post that pointed out that the Sten was supposed to be a stopgap weapon designed and produced in the dark days following Dunkirk and that a stopgap shouldn't still be in production after three years. So, should Britain have switched over to the Owen gun in about 1943 and relegated the Sten to a weapon that was dropped to continental resistance movements?
