My railgun feels heavier than my standard gun but in the water it is much lighter and more maneuverable. Why?
When in the water the railgun seems lighter and more maneuverable than a standard gun because the barrel to spear ratio is greater and the internal diameter of the barrel is also larger, therefore giving it more buoyancy. The front of a standard gun is always heavier because the spear protrudes further beyond the muzzle. Some try to compensate by adding a foam piece to create lift. This does work but increases the end profile of the gun making it more difficult to maneuver.
