Which of the following can happen during a "hammer follow" malfunction?

During a "hammer follow" malfunction, the hammer provides the potential for various issues related to firearm operation. The malfunction occurs when the hammer does not fully disengage from the sear after the trigger is released, leading to unintended hammer drops. This can result in several scenarios:

• Light strikes can occur because the hammer may not have enough energy behind it when it strikes the primer. This insufficient energy might not ignite the primer, leading to a failure in firing the cartridge.

• The malfunction can also cause a failure to fire since the round may not be discharged due to the hammer not striking with the appropriate force.

• Furthermore, if the hammer follows forward after the trigger is released while a round is in the chamber, it could potentially lead to an accidental discharge if the firearm's safety mechanisms are compromised.

Given that all these issues can arise during a hammer follow malfunction, it's accurate to say that all listed outcomes—light strikes, failures to fire, and accidental discharges—are possible. Therefore, selecting all the above as the correct response reflects a comprehensive understanding of the potential implications of a hammer follow malfunction in firearms.
