         5 . The discharge blocking device according to  claim 1 , further comprising a positioning lever configured to allow indication upon accommodation of the discharge blocking device within the magazine housing. 
     
     
         6 . The discharge blocking device according to  claim 1 , further comprising a dedicated space for accommodation of bullets. 
     
     
         7 . The discharge blocking device according to  claim 1 , further comprising a wedge configured to allow locking the discharge blocking device to the magazine housing. 
     
     
         8 . The discharge blocking device according to  claim 7 , wherein the wedge is movable by movement of the locking element. 
     
     
         9 . The discharge blocking device according to  claim 1 , further comprising at least one user identification unit. 
     
     
         10 . The discharge blocking device according to  claim 9 , wherein the user identification unit comprises biometric identification. 
     
     
         11 . The discharge blocking device according to  claim 9 , further comprising a mechanical identification override device. 
     
     
         12 . The discharge blocking device according to  claim 1 , wherein the locking element is configured to lock the device to the firearm in a locked state. 
     
     
         13 . A method for locking a magazine to a firearm and preventing accidental discharge, the firearm having a magazine housing and a trigger bar, and the method comprising:
 inserting a cover of the magazine into the magazine housing; and   engaging a locking element of the magazine with the trigger bar;   
       wherein the locking element is configured to allow blocking the trigger bar upon engagement therewith. 
     
     
         14 . A discharge blocking device compatible with a firearm having a magazine housing and a trigger bar, the discharge blocking device comprising:
 a cover, having a shape compatible with the magazine housing;   a base, covering a locking mechanism; and   a rotating locking element, having a blocking segment and at least partially accommodated inside the wall of the cover,   wherein the rotating locking element is configured to at least partially rotate between locked and unlocked states about an axis that is aligned with the longitudinal dimension of the cover, in order to allow blocking the trigger bar of the firearm with the blocking segment.   
     
     
         15 . The discharge blocking device according to  claim 15 , wherein the locking element is configured to lock the device to the firearm in a locked state. 
     
     
         16 . The discharge blocking device according to  claim 15 , wherein the rotating locking element comprises a rotating projection that is configured to rotate with rotation of the rotating locking element, and also configured to project from the cover to block the trigger bar. 
     
     
         17 . The discharge blocking device according to  claim 15 , wherein the rotating locking element comprises a bottom portion operably coupled to a locking mechanism within the base, and wherein movement of the bottom portion rotates the rotating locking element. 
     
     
         18 . The discharge blocking device according to  claim 17 , wherein the base comprises at least one gear coupled to a motor, and wherein the at least one gear is capable of moving the bottom portion between locked and unlocked states. 
     
     
         19 . The discharge blocking device according to  claim 15 , wherein the cover is configured to couple with the magazine housing. 
     
     
         20 . The discharge blocking device according to  claim 15 , further comprising a positioning switch configured to allow indication upon accommodation of the discharge blocking device within the magazine housing.
