四十五口径的手枪

To maintain the highest levels of secrecy, a misleading name was given to the device, and it was officially adopted as the Automatic Pistol, Caliber .30, Model 1918, Mark I. An order was subsequently placed with Rem-UMC for 100,000 Pedersen Devices on March 26, 1918, and it was soon-after increased to 133,450 devices.

为了保持秘密的最高水平，误导性的名字给该设备，并正式为自动手枪，口径。30，1918年通过的示范，马克一的命令，随后安排了雷姆为100，000佩德森联华电子设备于1918年3月26日，正是即将增加一十三万三千四百五十〇后设备。
