Firearm safety devices
First Claim
1. A firing pin block for a gun having a body and a firing pin for striking a cartridge in the gun, comprising:
- a bolt adapted to slide transversely through said body between a "fire" position and a "safety" position, said bolt having a non-circular opening through which the firing pin travels;
wherein the firing pin has a first collar and the bolt opening is constricted at one side so that the outer diameter of the pin collar exceeds the inner diameter of the opening at the constricted side, said collar being located on the pin so that when the bolt is in the safety position, the constricted side of the bolt opening prevents the firing pin collar from passing through the bolt opening and thereby preventing said firing pin from reaching the cartridge.

Abstract
A firearm is provided having a firing pin block which pulls the firing pin away from the hammer independently of the hammer actuator mechanism. A loaded chamber indicator includes a pivoting indicator lever resistant to breakage and jamming. The firearm also has a reversible thumb safety which is readily inserted, releasably retained and fully operational in either side of the firearm. An ambidextrous thumb safety includes two shaft portions each having integral levers and adapted to mate together to form a single shaft. A selective magazine catch is also provided which allows the shooter to select between a magazine catch mode and a magazine free fall mode.

5. In a gun having a spring-loaded hammer, a trigger and a sear cooperating with the trigger to releasably support the hammer until the trigger is pulled, the improvement comprising:
a safety having a shaft extending transversely through the gun, said shaft comprising two axially aligned shaft portions, each shaft portion having an end shaped substantially as a half cylinder and adapted to mate with the other half cylindrically shaped shaft portion when assembled to form a complete cylinder, each shaft portion having an integral manually actuable lever at the other end of the shaft portion for pivoting the safety shaft when assembled between a "fire" position and a "safety" position, and at least one of said shaft portions having means for engaging the sear to prevent release of the support of the hammer when the safety shaft is in the safety position. - View Dependent Claims (6, 7, 8)

9. In a gun having a spring-loaded hammer, a trigger, and a sear cooperating with the trigger to releasably support the hammer until the trigger is pulled, the improvement comprising:
a reversible safety comprising a shaft having a manually actuable lever at one end and a free end adapted to be inserted transversely through the gun selectively from either side of the gun, said shaft defining a first transverse position when the free end is inserted from one side and defining a second transverse position when the shaft free end is inserted from the other side of the gun, said lever for pivoting the shaft between a first "fire" position and a first "safety" position when the shaft is in the first transverse position, said lever further for pivoting the shaft between a second "fire" position and a second "safety" position when the shaft is in the second transverse position, said shaft having means for engaging the sear to prevent release of the hammer when the shaft is in either of said first or second safety positions associated with said first and second transverse positions, respectively. - View Dependent Claims (10, 11, 12, 13)

14. In a gun having a firing pin which has one end protruding beyond a hammer striking surface and adapted to be struck at said one end causing the other end of the pin to strike a cartridge within the gun, the improvement comprising:
means for withdrawing and releasably holding the firing pin below the hammer striking surface to prevent the hammer from reaching the firing pin. - View Dependent Claims (15, 16, 17)

18. In a gun having a spring-loaded hammer, a trigger and a sear cooperating with the trigger to releasably support the hammer until the trigger is pulled, the improvement comprising:
-
safety means including a shaft having a manually actuable lever at one end and an opposite free end adapted to be inserted transversely through the gun from a side thereof, said lever rotating the shaft between fire and safety positions; and said shaft having means to engage the sear and thereby prevent a release of the hammer and a discharge of the gun when said lever rotates said shaft to the safety position. - View Dependent Claims (19, 20, 21, 22)
