Later production models have a larger trigger guard, following complaints by soldiers stationed in Manchukuo that it was difficult to fire the trigger while wearing gloves. Some of these models also have a knurled steel cocking knob instead of the standard "slotted" cocking knob. After 1940, an auxiliary magazine spring was added to assist in reloading. A redesigned cocking knob was implemented in 1944 in order to simplify production. The Type 14 also lacks the grip safety used on the previous models.
