The recoil of a gun can be thought of as consisting of two separate components: the degree that the gun accelerates you backwards, and the degree that the gun wants to point to the ceiling. The interplay between those two effects depend on how well the barrel is in line with the center of mass of the gun.
If the barrel is not perfectly in line with the center of mass of a gun, then firing it will effect a rotational force on the gun -- if it were to fire while floating free in space, it would start to spin on its axis. When you are holding the gun in your hands when firing it, it will recoil upwards, because the gun barrel is above the center of mass of the gun. That is to say, the combination of (gun + your arms) is spinning upwards. If you were to shoot a gun with perfectly straight arms (which you can never manage in real life because your body is not that strong, but nevermind that) while floating in space, you would start spinning backwards with your whole body. Unless you fire it from your center of mass, somewhere near your hip.
The more a gun's barrel is in line with its center of mass, the less it will want to point to the ceiling when you fire it.
None of this affects the amount of backwards acceleration however; the real opposite reaction of the bullet being fired. That is always and entirely in the opposite direction of the bullet (byproducts of firing notwithstanding). A good gun design can minimize the rotational counterforce, by having the right balance, and the reciprocating weights can help with this; but the translational counterforce (being accelerated backwards) cannot be affected this way, because of conservation of momentum.
tl;dr Firing a typical gun in space will both accelerate you backwards, and rotate you upwards. A gun like the Vector can reduce or even completely stop the rotation effect, but it cannot reduce or redirect the flying-backwards effect.
