Frequently Asked Questions

What are the main differences between pre-war and late-war Nanbu Type 14 pistols?

Late-war Nanbu Type 14 pistols feature a larger trigger guard for easier trigger reset, a magazine retention spring to prevent drops, simplified sights, and often exhibit rougher machining and finishing compared to their pre-war counterparts.

Why was the trigger guard enlarged on late-war Nanbu Type 14 models?

The enlarged trigger guard on late-war Nanbu Type 14 pistols was a design modification intended to allow a gloved hand to more easily access and release the trigger, improving usability in various conditions.

What issue did the magazine retention spring on the late-war Nanbu Type 14 address?

The addition of a riveted flat spring to the frame of late-war Nanbu Type 14 models was implemented to prevent magazines from unintentionally dropping out of the pistol due to inertia, a common problem with the earlier design.

How did the magazines for the Nanbu Type 14 pistol change over its production?

Early Nanbu Type 14 magazines were nickel-plated with aluminum bases. Later, blued magazines with alloy bases and squared-off followers were introduced, reflecting wartime production changes and material availability.
