Remove one of the other springs and take it to a hardware store or home improvement warehouse to be compared to a similar spring for replacement.
It is not a spring at all, it is a replacement for a spring. When installed your spring will be removed from the gun and be replaced with a Gas Shock. The firing cycle, sound, and feel is much more solid. Im a huge advocate of gas rams over springs and feel it should be thestandard for all new age air rifles. Springs are old technology. My 2.
The hammer spring is the primarily safety feature. Depending on the extent of the mechanical failure the firing pin spring could be providing protection also. Do not confuse the firing pin spring with the striker pin spring which is the spring that pushs (strikes) the firing pin into the round which ignites the primer.
Remove the rear of the action by depressing the two buttons on each side of the action. The back and springs will all pull right out. Simply slide the cocking handle off the front of the bolt, and the entire bolt will come out of the back of the action. Remove the pin from the side of the bolt, and the firing pin will fall right out. Be careful not to lose the spring on the firing pin; they are difficult to replace.

No. Spring must be cocked before each shot.
Take it to a gunsmith.
