Concealable firearm

A firearm comprising

• (a) a frame including a handle portion and having at least two generally parallelably opposed spaced members defining
• (i) in part first and second side surface areas of said firearm, and
• (ii) an internal space therebetween,
• said spaced opposed members generally lying in a pair of opposed, spaced, parallel imaginary planes,
• (b) a barrel pivotally connected to said frame and
• (i) having a chamber for receiving a cartridge, said chamber having a cylindrically shaped inner wall,
• (ii) having a bore through which a bullet fired from said cartridge travels, and
• (iii) movable between at least two operative positions,
• first operative position in which said firearm can be fired, and
• a second operative position in which a cartridge can be manually loaded into said chamber;
• (c) a hammer pivotally carried on said frame and at least partially positioned in said internal space;
• (d) a trigger carried on said frame and operatively associated with said hammer, said trigger being manually depressed to pivotally displace and release said hammer;
• (e) spring means mounted on said frame and operatively associated with said hammer;
• (f) firing pin means carried on said hammer, said hammer and firing pin means being movable between at least two operative positions,
• (i) a normal operative position with said hammer at rest in a state of equilibrium with said trigger and said spring means, and
• (ii) an operative position with said hammer pivotally displaced from said normal operative position and maintained by said trigger in a cocked position such that after said trigger releases said hammer, said compressed spring means forces said hammer to pivot on said frame such that said firing pin means strikes and fires a cartridge carried in said chamber;
• said barrel and handle portion having surfaces defining in part said first and second side surface areas of said firearm, said barrel and handle surfaces generally lying in said opposed imaginary planes with said spaced member of said frame,
• said barrel having a minimum barrel wall thickness represented by the shortest of the distances from said cylindrical wall of said chamber to said surfaces defining said first and second side surface areas of said firearm, the shortest distance between said imaginary planes representing the greatest width of said firearm and being equivalent to the diameter of said inner wall of said chamber added to twice said minimum barrel wall thickness,
• said minimum barrel wall thickness generally being at least sufficient to prevent significant damage to the barrel when said firearm is fired for the first time, said significant damage to the barrel preventing further use of said firearm.
