A compressed gas cartridge dispensing system capable of dispensing at least two different capacities of non-threaded neck compressed gas cartridges as well as optionally dispensing all cartridges having a ⅜-24 neck thread. The standard 12-gram CO2 non-threaded neck compressed gas cartridge fits this dispenser. The same dispensing system is also capable of dispensing larger capacity cartridges having a neck dimensioned smaller than a ⅜-24 female thread minor diameter with a water capacity in the range of 16 to 50 ml. Obvious advantages to the dispensing system are added options offering increased versatility for harnessing compressed gas cartridges of differing capacities in a unique dispenser including a novel cartridge storage feature.
