The type 94 pistol was originally developed for export sales, and Japanese catalogues offered it for sale in South America before the war. It seems highly unlikely that a weapon specifically developed to be used in treacherous surrender circumstances, such as depicted in this video, would have been offered for commercial sale. There is no doubt that this is a highly dangerous weapon, due to the sear projecting from the left side of the gun. Accordingly, it could hypothetically be fired by depressing the external projection of the sear when the gun is held in a non-normal firing position , but such firing would in all probability injure the shooter as much as the intended target. While the use of this arm in "false surrender" circumstances has been discussed for years, I am aware of no evidence that this was ever tried, nor that such use was ever covered in any Japanese Army training manuals. If it happened, it was most likely a "one off" situation-- The gun was certainly not designed with this use in mind. Essentially, the type 94 was just a poorly constructed and highly dangerous weapon-- It appears that the "fake surrender" usage is a fabrication.
