A compressed gas firearm is capable of firing either cartridges filed with pellets, or solid unitary projectiles. The firearm includes a barrel that is hinged to the butt so that cartridges or an adapter can be inserted into the end of the barrel. A compressed gas chamber in the butt is capable of releasing compressed gas against the rear of the cartridge or adapter to fire the pellets or the unitary projectile. When the adapter is inserted into the barrel, a projectile can then be inserted into the adapter before the barrel is closed for firing. Indentations may be formed in the rear of the barrel to facilitate removal of the cartridges or adapter.

1. A combination compressed gas operated gun, projectile cartridge, and adapter, the gun comprising: a butt;a firing mechanism mounted in the butt and including a compression chamber which uses compressed gas to eject one or more projectiles; anda barrel that is pivotally mounted to the butt, wherein the barrel can be pivoted with respect to the butt to an open position at which the cartridge or adapter can be inserted into the barrel, and wherein the barrel can also be pivoted with respect to the butt to a closed position which brings a rear end of the cartridge or adapter in the barrel adjacent to the compression chamber such that compressed gas in the compression chamber can be used to eject the one or more projectiles from the cartridge or adapter and down the barrel;wherein the end of the barrel adjacent the butt comprises a widened internal diameter portion;the projectile cartridge comprising: a first generally cylindrical outer shell comprising a first expanded diameter hoop on a rear of the cartridge, configured to be received in the widened internal diameter portion of the barrel to prevent the cartridge from moving down the barrel when the gun is fired;a generally circular rear cover that is detachably mounted inside the rear of the cylindrical shell;a generally cylindrical front cover that is detachably mounted inside the cylindrical outer shell such that a first space is formed between the front and rear covers; andat least a first one of the projectiles mounted in the first space,wherein the cartridge is configured such that when the cartridge is inserted in the gun, and compressed gas in the compression chamber is released to fire the gun, the front cover, rear cover and first projectile all separate from the outer shell and travel down the barrel;the adapter comprising: a second generally cylindrical outer shell comprising a second expanded diameter hoop on a rear of the adapter, configured to be received in the widened internal diameter portion of the barrel to prevent the adapter from moving down the barrel when the gun is fired; anda hollow, cylindrical interior extending the length of the adapter;the adapter being configured for at least a second one of the projectiles to be placed in the interior by an end user such that the adapter holds the second projectile adjacent the compression chamber when the barrel is in the closed position such that compressed gas in the compression chamber can be used to fire the second projectile down the barrel;wherein the adapter and the projectile cartridge are interchangeable with one another within the gun. 2. The combination of claim 1, wherein the gun further comprises at least one indentation in a rear end of the barrel to facilitate the removal of the cartridge or adapter from the barrel. 3. The combination of claim 2, wherein the at least one indentation is crescent shaped. 4. The combination of claim 2, wherein a notch is formed in the at least one indentation to further facilitate removal of a cartridge from the barrel. 5. The combination of claim 2, wherein the at least one indentation comprises first and second indentations formed on opposite sides of the rear end of the barrel. 6. The combination of claim 5, wherein a smaller notch is formed in each of the first and second indentations. 7. The combination of claim 1, wherein a front end of the adapter is beveled to facilitate insertion of the adapter into the barrel. 8. The combination of claim 1, wherein the adapter further comprises an expanded diameter reinforcing portion on an outer circumference of the adapter at a position adjacent the second rear hoop, wherein the expanded diameter portion serves to reinforce the adapter. 9. The combination of claim 8, further comprising a fixing portion on the expanded diameter portion, the fixing portion protruding out from the expanded diameter portion and acting to hold the adapter in the barrel. 10. The combination of claim 9, wherein the fixing portion forms a ring that protrudes out from the expanded diameter portion. 11. The combination of claim 1, wherein the front cover of the cartridge is mounted inside the cylindrical outer shell of the cartridge at an interim position down the length of the shell such that the front cover is spaced back away from a front end of the shell. 12. The combination of claim 1, further comprising at least two points of attachment between the outer edges of the front cover and the inner wall of the cylindrical shell of the cartridge. 13. The combination of claim 1, wherein the cartridge further comprises an expanded diameter reinforcing portion on an outer circumference of the shell at a position adjacent the first rear hoop, wherein the expended diameter cylindrical portion serves to reinforce the cartridge. 14. The combination of claim 1, wherein the first projectile is of a different type than the second projectile. 15. The combination of claim 1, wherein the first projectile comprises a plurality of projectiles. 16. The combination of claim 1, wherein the second projectile is exactly one projectile. 17. The combination of claim 1, wherein the first projectile comprises one or more pellets. 18. The combination of claim 1, wherein the second projectile comprises a slug. 19. A combination compressed gas operated gun, projectile cartridge, and adapter, the gun comprising: a butt;a firing mechanism mounted in the butt and including a compression chamber which uses compressed gas to eject one or more projectiles; anda barrel that is pivotally mounted to the butt, wherein the barrel can be pivoted with respect to the butt to an open position at which the cartridge or adapter can be inserted into the barrel, and wherein the barrel can also be pivoted with respect to the butt to a closed position which brings a rear end of the cartridge or adapter in the barrel adjacent to the compression chamber such that compressed gas in the compression chamber can be used to eject the one or more projectiles from the cartridge or adapter and down the barrel;wherein the end of the barrel adjacent the butt comprises a widened internal diameter portion;the gun further comprising at least one indentation in a rear end of the barrel to facilitate the removal of the cartridge or adapter from the barrel;the projectile cartridge comprising: a first generally cylindrical outer shell comprising a first expanded diameter hoop on a rear of the cartridge, configured to be received in the widened internal diameter portion of the barrel to prevent the cartridge from moving down the barrel when the gun is fired;a generally circular rear cover that is detachably mounted inside the rear of the cylindrical shell;a generally cylindrical front cover that is detachably mounted inside the cylindrical outer shell such that a first space is formed between the front and rear covers; andat least a first one of the projectiles mounted in the first space;the adapter comprising: a second generally cylindrical outer shell comprising a second expanded diameter hoop on a rear of the adapter, configured to be received in the widened internal diameter portion of the barrel to prevent the adapter from moving down the barrel when the gun is fired; anda hollow, cylindrical interior extending the length of the adapter;the adapter being configured for at least a second one of the projectiles to be placed in the interior by an end user such that the adapter holds the second projectile adjacent the compression chamber when the barrel is in the closed position such that compressed gas in the compression chamber can be used to fire the second projectile down the barrel;wherein the adapter and the projectile cartridge are interchangeable with one another within the gun. 20.
