Full specifications
Performance
Speed, range, altitude and engagement capability.
- Effective range
Distance at which the weapon reliably hits point targets. Higher extends engagement envelope.
- 50 m Stronger than 50% of pistols
- Muzzle velocity
Projectile speed leaving the barrel. Higher means flatter trajectory and better armor penetration.
- 365 m/s Stronger than 60% of pistols
Firepower
Armament, payload and guidance.
- Main armament
Primary weapon: main gun, cannon or missile type.
- 9×19 mm Parabellum

- 9 mm
- Ammunition
Rounds carried (main gun) or standard magazine capacity.
- 17 Stronger than 86% of pistols
Physical
Dimensions, weight and crew.
- Length
Overall length including gun/probe where applicable.
- 0.2 m
- Empty weight
Weight without fuel, ammunition or crew.

- Crew
Personnel required to operate. Fewer reduces exposure; autoloaders trade a loader for mechanical complexity.
- 1
- Barrel length
Barrel length — longer improves muzzle velocity and accuracy, shorter improves handling.

Program
Cost, production scale and operators.
- Unit cost
Approximate flyaway/unit cost where public. Defense pricing varies hugely by contract, offsets and configuration. Lower is cheaper.
