Abstract
Abstract An elongated tubular barrel is provided having front and rear end portions. The rear end portion of the barrel includes chamber structure for removably chambering a cartridge in the barrel. Firing pin structure for firing a cartridge chambered in the barrel is provided and is shiftable between ready and firing positions. A palm grip is supported from the rear end portion of the barrel of a size to be substantially enclosed within one hand with the forward end of the barrel of the weapon projecting forwardly and outwardly between adjacent fingers of the hand. The forward end of the barrel tapers in wall thickness to a circumferentially unobstructed thin wall portion at the forward terminal end of the barrel, whereby the forward terminal end may be thrust forwardly against a flesh target and at least partially penetrate the target substantially simultaneously with the firing of a cartridge chambered in the barrel.

Claim 1
Independent Claim
321 words
A close combat weapon comprising a tubular barrel having front and rear end portions, the rear end portion of said barrel including chamber means for removably chambering a cartridge in said barrel, firing pin means for firing a cartridge chambered in said barrel and shiftable between ready and firing positions, a palm grip supported from the rear end portion of said barrel and of a size to be substantially enclosed within one hand of a user of said weapon with the forward end of said barrel projecting forwardly and outwardly between adjacent fingers of said hand, the forward end of said barrel tapering in wall thickness to a circumferentially unobstructed thin wall portion at the forward terminal end of said barrel, whereby said forward terminal end may be thrust forwardly against a flesh target and at least partially penetrate said target substantially simultaneously with the firing of said cartridge, said palm grip including a rearwardly facing shiftable portion thereof supported for limited front to rear shifting relative to said barrel between forward and rearward positions, said shiftable portion being operatively associated with said firing pin means to effect movement of the latter from said ready position to said firing position in response to shifting of said shiftable portion from said rear position to said forward position, said palm grip including a main body having a rearwardly facing rear surface, said shiftable portion being shiftably supported from said body and projecting rearwardly of said rear surface, detent means connected between said shiftable portion and said main body yieldably resisting forward movement of said shiftable portion, whereby a forward thrust on said shiftable portion relative to said main body above a predetermined value will effect sudden forward snap action movement action of said shiftable portion relative to said body to the forward position thereof and thus effect snap action movement of said firing means pin from said ready position to said firing position.
Claim 2
Dependent Claim
321 words
A close combat weapon comprising a tubular barrel having front and rear end portions, the rear end portion of said barrel including chamber means for removably chambering a cartridge in said barrel, firing pin means for firing a cartridge chambered in said barrel and shiftable between ready and firing positions, a palm grip supported from the rear end portion of said barrel and of a size to be substantially enclosed within one hand of a user of said weapon with the forward end of said barrel projecting forwardly and outwardly between adjacent fingers of said hand, the forward end of said barrel tapering in wall thickness to a circumferentially unobstructed thin wall portion at the forward terminal end of said barrel, whereby said forward terminal end may be thrust forwardly against a flesh target and at least partially penetrate said target substantially simultaneously with the firing of said cartridge, said palm grip including a rearwardly facing shiftable portion thereof supported for limited front to rear shifting relative to said barrel between forward and rearward positions, said shiftable portion being operatively associated with said firing pin means to effect movement of the latter from said ready position to said firing position in response to shifting of said shiftable portion from said rear position to said forward position, said palm grip including a main body having a rearwardly facing rear surface, said shiftable portion being shiftably supported from said body and projecting rearwardly of said rear surface, detent means connected between said shiftable portion and said main body yieldably resisting forward movement of said shiftable portion, whereby a forward thrust on said shiftable portion relative to said main body above a predetermined value will effect sudden forward snap action movement action of said shiftable portion relative to said body to the forward position thereof and thus effect snap action movement of said firing means pin from said ready position to said firing position.
Claim 3
Dependent Claim
273 words
A close combat weapon comprising a tubular barrel having front and rear end portions, the rear end portion of said barrel including chamber means for removably chambering a cartridge in said barrel, firing pin means for firing a cartridge chambered in said barrel and shiftable between ready and firing positions, a palm grip supported from the rear end portion of said barrel and of a size to be substantially enclosed within one hand of a user of said weapon with the forward end of said barrel projecting forwardly and outwardly between adjacent fingers of said hand, said palm grip including at least a portion thereof supported for limited front to rear shifting relative to said barrel and yieldingly biased toward its rearmost position, said palm grip portion being operatively associated with said firing pin means for shifting the latter from the ready position to the firing position in response to forward shifting of said palm grip portion from its rearmost position toward its forwardmost position, said palm grip including a main body having a rearwardly facing rear surface, said shiftable portion being shiftably supported from said body and projecting rearwardly of said rear surface, detent means connected between said shiftable portion and said main body yieldably resisting forward movement of said shiftable portion, from said rearmost position whereby a forward thrust on said shiftable portion relative to said main body above a predetermined value will effect sudden forward snap action movement of said shiftable portion relative to said body to said forward position thereof and thus effect snap action movement of said firing pin means from said ready position to said firing position.
Claim 4
Dependent Claim
273 words
A close combat weapon comprising a tubular barrel having front and rear end portions, the rear end portion of said barrel including chamber means for removably chambering a cartridge in said barrel, firing pin means for firing a cartridge chambered in said barrel and shiftable between ready and firing positions, a palm grip supported from the rear end portion of said barrel and of a size to be substantially enclosed within one hand of a user of said weapon with the forward end of said barrel projecting forwardly and outwardly between adjacent fingers of said hand, said palm grip including at least a portion thereof supported for limited front to rear shifting relative to said barrel and yieldingly biased toward its rearmost position, said palm grip portion being operatively associated with said firing pin means for shifting the latter from the ready position to the firing position in response to forward shifting of said palm grip portion from its rearmost position toward its forwardmost position, said palm grip including a main body having a rearwardly facing rear surface, said shiftable portion being shiftably supported from said body and projecting rearwardly of said rear surface, detent means connected between said shiftable portion and said main body yieldably resisting forward movement of said shiftable portion, from said rearmost position whereby a forward thrust on said shiftable portion relative to said main body above a predetermined value will effect sudden forward snap action movement of said shiftable portion relative to said body to said forward position thereof and thus effect snap action movement of said firing pin means from said ready position to said firing position.
