A very interesting article about the Chinese .45 ACP Broomhandle.

Since the C-96 was considered a highly effective fighting weapon, Yen had no desire to replace the it with another design. So instead he offered a cash reward to the workers at his arsenal to produce a C-96 chambered for the sam e .45 cartridge as their Thompson. And so one of the rarest and most exotic C-96 variations was born, the .45 Shansi Broomhandle.
