1. A firearm apparatus configured to fire at least one bullet of a cartridge, comprising:
a barrel comprising an inner-barrel-diameter configured to receive the cartridge;
a cartridge-chamber configured to receive the cartridge from an ammunition feeding unit and wherein said cartridge-chamber is formed by a number of wall surfaces; and
the ammunition feeding unit comprising a firearm magazine comprising a pair of lips configured to house a next cartridge to be fired, wherein only the wall surfaces and respective upper surfaces of said pair of lips are coated by a self-luminous glowing matter to thereby illuminate only said cartridge-chamber so an inside of said cartridge-chamber is visible, when said cartridge-chamber is not enclosed, including in very low light (less than 200 lumen) to zero light conditions;
a rear discharge opening formed behind said barrel, aligned with said barrel, the cartridge comprising a casing comprises a primer and encloses a sealed inner-casing space that contains gunpowder; and
wherein upon activating the primer by a firing activator of the firearm apparatus, the primer explodes to thereby detonate the gunpowder, forming propellant gases inside the cartridge that are directed both forward and backward as follows:
a) forward: firing of the at least one bullet via said barrel; and
backward: pushing, by a recoil force Fp, the casing, being a counterweight to the at least one bullet, to thereby eject the casing from the firearm apparatus via said rear discharge opening and said cartridge-chamber.
