XP-20
For its size the xp-20 is great small pistol.
It has nearly the range of a xp-70, although it is much smaller. It will fit in many side pockets.
Its water capacity is limited by its size, but as the shots use not as much water as other xps, you get an acceptable number of shots, but obviously this is not your gun of choice if you want to get someone very wet, it is rather a side-arm.
You cannot fill it entirely, nor use up all the water.
The route of the water from the tank to the nozzle is a tube which goes to the end of the water reservoir. The main problem about this is that the water-intake tube must be submerged in order for water to be fired, otherwise, you will only be firing only air or mist. Therefore the angles at which the weapon can be pointed and fired are limited.
But these flaws don't keep it from being one of the best small pistols.
