The "16 Shot" prototype Nambu

They were manufactured by the Tokyo Artillery Arsenal in Koishikawa circa 1921. They were never officially adopted by the Japanese and all of the known examples being discovered by returning GI's after WWII.

These pistols were a very limited design with only a few ever recorded or found. (the highest serial number found is 14.) These were a completely new prototype design that was intended to utilize some of the best features of both the Grandpa and Papa Model 1902 Nambu pistol combined with the experimental increase in magazine capacity that was being developed by several European countries.

The pistol is massive, as the magazine is almost twice as wide as the standard Type 14 Nambu with the grip frame measuring approximately 1 1/4 inches wide. Interestingly they also made the upper receiver wider and also the breech bolt wider and flatter to compensate for the increased magazine width. Note the large concave cocking knob.
It has many unique features such as the short front and rear bridges with an integral barrel/barrel extension, lightening cuts on both sides of the barrel extension, massive enlarged trigger guard bow and wide trigger, the magazine release is a small button mounted on the front of the lower grip strap. Fitted with a short tangent rear sight.
