With decently leveled Magnum Force and fully leveled multishot mods such as Barrel Diffusion and Lethal Torrent these pistols visibly fire 2-3 bolts per shot. When used over a longer range this results in the Akbolto having the effective use of "spray and pray" weapons whilst retaining respectable damage out-put and ammo economy.
The bolts spawn as physical objects at the muzzle of the Akbolto.
If an enemy is standing right in front of you, so that the muzzle is inside of it, you will sometimes not be able to hit, because the Akbolto is non-hitscan and pretty long, so the bolts spawn behind the hitbox of that enemy.
Also if taking cover behind a thick object (i.e. door case) you will not be able to shoot anything but the wall in front you, if the muzzle is inside of that object.
