Claim 1
1 . A method for coding firearm-related components to reduce the risk of loading incorrect ammunition into firearms, comprising: associating a plurality of firearm-related components including at least a firearm and at least one magazine with a specific caliber of ammunition; marking at least the firearm and the at least one magazine with a first identifier corresponding to the specific caliber, wherein the first identifier is assigned according to a predetermined mapping of identifiers to calibers; and when differentiating among multiple firearms of the same caliber, incorporating a sub-coding system that includes at least one second identifier assigned according to a predetermined mapping of identifiers to specific firearms of the same caliber and applied to at least a portion of at least the firearm and the at least one magazine, wherein the first identifier identifies the caliber and the second identifier identifies a specific firearm; wherein at least one of the first identifier and the second identifier is a color, figure, icon, graphical pattern, symbol, text, numeric, alphanumeric, and/or other visual indication feature, or combination thereof. associating a plurality of firearm-related components including at least a firearm and at least one magazine with a specific caliber of ammunition; marking at least the firearm and the at least one magazine with a first identifier corresponding to the specific caliber, wherein the first identifier is assigned according to a predetermined mapping of identifiers to calibers; and when differentiating among multiple firearms of the same caliber, incorporating a sub-coding system that includes at least one second identifier assigned according to a predetermined mapping of identifiers to specific firearms of the same caliber and applied to at least a portion of at least the firearm and the at least one magazine, wherein the first identifier identifies the caliber and the second identifier identifies a specific firearm; wherein at least one of the first identifier and the second identifier is a color, figure, icon, graphical pattern, symbol, text, numeric, alphanumeric, and/or other visual indication feature, or combination thereof.
