Making a Functional Pistol in Besiege

Consider it like this: a real pistol works by using expanding gasses to push against the bullet and get it out of the barrel. My pistol works by using a vacuum on the front of the bullet therefore allowing the gasses on the other side of the bullet to expand and push it out of the barrel. This is extreme realism.
