Why 9mm for Submachine Guns?
The choice of 9mm for submachine guns like the MP5 offers several practical advantages:
- Controllable Recoil: The relatively mild recoil of the 9mm cartridge allows for high rates of fire and easier control during automatic fire, improving accuracy, especially in dynamic situations.
- Magazine Capacity: Its compact size permits higher magazine capacities compared to larger rifle cartridges, providing more sustained firepower.
- Terminal Ballistics: While not as powerful as a rifle round, a 9mm round delivers sufficient energy for typical submachine gun engagement distances, particularly against unarmored targets.
- Logistical Simplicity: As a ubiquitous pistol cartridge, 9mm simplifies ammunition logistics, especially for forces that also issue 9mm service pistols.
