Ballistics
Velocity only, no drag model: no published ballistic coefficient is on file for 9mm Bergmann No.3, so this is the shape gravity alone gives the advertised velocity. Drag would steepen it. The tool below solves real loads through their published G1 or G7 model.

Size vs familiar rounds
Drawn at true 1:1 — every case is accurate relative to the others. Absolute size depends on your screen's pixel density, so measuring one against a real ruler may be off. 9mm Bergmann No.3 is highlighted below.

History
Developed by Theodor Bergmann in 1894 for his prototype semi-automatic pistol, the 9mm Bergmann No.3 (actually approximately 8mm) is among the earliest purpose-designed semi-automatic pistol cartridges ever produced. The Bergmann pistol was a landmark firearm in the development of the self-loading handgun, and this cartridge is a historically significant collector's item.
