1. A firearm for implementing an improved 9 mm cartridge having a 9 mm bullet and a cartridge casing, the firearm comprising: a barrel, wherein the barrel is configured to operably interact with a 9 mm bullet;a chamber, wherein the chamber includes at least one chamber portion sized and shaped to operably associate with a .45 caliber cartridge casing, wherein the .45 caliber cartridge casing has a length approximately equal to 0.9880 inches and wherein the length may vary by a tolerance range of approximately ±0.004 inches; anda free-bore, wherein the free-bore includes a first free-bore portion having a first free-bore portion diameter and a second free-bore portion having a second free-bore portion diameter, wherein the second free-bore portion includes a second free-bore portion wall that is tapered between about 1° to about 2° such that the second free-bore portion diameter is smaller than the first free-bore portion diameter, and wherein the free-bore sized and shaped to operably associate with at least a portion of the cartridge casing and the 9 mm bullet, andwherein the 9 mm bullet weights at least 90 grains and is configured for operation with a 9 mm firearm, and the .45 caliber cartridge casing is configured to operate with a .45 caliber firearm, the .45 caliber cartridge casing having a case bottom portion communicated with a case top portion via a case middle portion having a length that is approximately equal to 0.0236 inches and tapered at an angle of 20 degrees relative to a plane disposed parallel to said case bottom portion, wherein said angle may vary by a tolerance range of approximately ±2 degrees, wherein the case bottom portion, the case middle portion and the case top portion define a case cavity and wherein the case top portion includes a top opening communicated with the case cavity, the top opening sized to interact with the 9 mm bullet, wherein the 9 mm bullet is frictionally associated with the top opening such that at least a portion of the 9 mm bullet is disposed within the case cavity, a means for propelling the 9 mm bullet to a velocity of at least 1600 feet per second, wherein the means for propelling is at least partially disposed within the casing cavity, and a cap, wherein the cap is associated with the case bottom portion such that when the cap is engaged, the cap causes the means for propelling the 9 mm bullet to propellingly interact with the 9 mm bullet. 2. The firearm of claim 1, wherein said at least one chamber portion includes a first chamber portion having a first chamber portion length equal to about 0.7450 inches and a first chamber portion width equal to about 0.4660 inches. 3. The firearm of claim 1, wherein said at least one chamber portion includes a second chamber portion having a second chamber portion length equal to about 0.1146 inches and a second chamber portion width, wherein said second chamber portion width decreases from about 0.4660 inches to 0.3828 inches. 4. The firearm of claim 1, wherein said at least one chamber portion includes a third chamber portion having a third chamber portion length equal to about 0.1384 inches and a third chamber portion width equal to about 0.3828 inches. 5. The firearm of claim 1, wherein the free-bore includes a free-bore length equal to about 0.1520 inches. 6. The firearm of claim 1, wherein the first free-bore portion diameter is equal to about 0.3828 inches. 7. The firearm of claim 1, wherein the second free-bore portion diameter is tapered from a second free-bore diameter of about 0.3828 inches to a second free-bore diameter of about 0.3550 inches. 8. The firearm of claim 1, wherein said at least one chamber portion includes at least one of a first chamber portion having a first predetermined tolerance range, a second chamber portion having a second predetermined tolerance range and a third chamber portion having a third predetermined tolerance range. 9. The firearm of claim 8, wherein at least one of said first predetermined tolerance range, said second predetermined tolerance range and said third predetermined tolerance range is equal to about ±10%.
