发展历程M1卡宾枪的研制原本是美国陆军要为二线部队提供一种用于替代制式手枪的自卫武器,这个要求最初是在1938年提出的,其设想是研制一种类似于卡宾枪的肩射武器,发射中等威力的弹药,比标准的0.45英寸(11.43mm)半自动手枪或转轮手枪有更远的有效射程,但要比M1伽兰德步枪更容易操作,携带更方便。这些要求实际上与现在流行的单兵自卫武器(PDW)的概念差不多。 History M1 Carbine was originally developed by the United States Army to provide second-line units with a self-defense weapon to replace the standard pistol. This requirement was first proposed in 1938 with the idea of ​​developing a shoulder-fired weapon similar to a carbine, Medium-firing ammunition firing more effective range than a standard 0.45-inch (11.43mm) semi-automatic pistol or revolver, but easier to operate and easier to carry than the M1 Garand rifle. These requirements are in fact similar to the concepts of the now-defunct Personal Defense Self-Defense Weapons (PDW).
