         2 . The magazine shell of  claim 1 , further comprising an ejector. 
     
     
         3 . The magazine shell of  claim 2 , wherein the ejector is an integral feature of the magazine shell. 
     
     
         4 . The magazine shell of  claim 1 , further comprising at least one capacity feature. 
     
     
         5 . The magazine shell of  claim 4 , wherein the at least one capacity feature comprises at least one selected from the group of a magazine capacity label or a magazine capacity indicator. 
     
     
         6 . The magazine shell of  claim 1 , wherein the magazine is a pistol magazine. 
     
     
         7 . The magazine shell of  claim 1 , wherein the magazine shell is designed to function similar to a STANAG magazine. 
     
     
         8 . The magazine shell of  claim 1 , further comprising a functional configuration, wherein in the functional configuration an uppermost portion of at least one feed lip of the magazine is approximately at the same height as a top of the magazine shell. 
     
     
         9 . The magazine shell of  claim 1 , further comprising a magazine catch lever for actuating the internal magazine catch feature. 
     
     
         10 . The magazine shell of  claim 9 , wherein the magazine catch lever allows the magazine to be disengaged from the magazine shell while the magazine shell remains in the firearm receiver. 
     
     
         11 . A modular magazine assembly comprising:
 a magazine shell comprising an internal cavity; and   a magazine disposed within the internal cavity of the magazine shell, wherein:   the magazine shell comprises a magazine catch cavity for securing the magazine shell relative to a firearm receiver; and   the magazine shell comprises an internal magazine catch feature for securing the magazine within the magazine shell.   
     
     
         12 . The modular magazine assembly of  claim 11 , wherein the magazine is a handgun magazine and the magazine shell is designed to interface with an AR-15 receiver. 
     
     
         13 . The modular magazine assembly of  claim 11 , further comprising an ejector. 
     
     
         14 . The modular magazine assembly of  claim 13 , wherein the ejector is an integral feature of the magazine shell. 
     
     
         15 . The modular magazine assembly of  claim 11 , wherein the magazine shell comprises at least one capacity feature. 
     
     
         16 . The modular magazine assembly of  claim 15 , wherein the at least one capacity feature comprises at least one selected from the group of a magazine capacity label or a magazine capacity indicator. 
     
     
         17 . The modular magazine assembly of  claim 11 , further comprising a functional configuration, wherein in the functional configuration an uppermost portion of at least one feed lip of the magazine is approximately at the same height as a top of the magazine shell. 
     
     
         18 . The modular magazine assembly of  claim 11 , further comprising a magazine catch lever for actuating the internal magazine catch feature. 
     
     
         19 . The modular magazine assembly of  claim 18 , wherein the magazine catch lever allows the magazine to be disengaged from the magazine shell while the magazine shell remains in the firearm receiver. 
     
     
         20 . The modular magazine assembly of  claim 11 , wherein the magazine shell is designed to receive multiple different size magazines.
