An unintended discharge may be produced by an incompatibility between firearm design and usage, such as the phenomenon of cooking off a round in a closed bolt machine gun, a mechanical malfunction as in the case of slamfire in an automatic weapon, or be user induced due to training ...
GSR may be present when an individual discharged a firearm or was close by when a discharge occurred. [6] GSR has been observed to undergo both secondary and tertiary transfers, meaning the presence of GSR may be attributed to the persistence of the residue and the unpredictability of human interaction.

Semi-automatic, self-loading, or autoloading is a firearm action that, after a single discharge, automatically performs the feeding and ignition procedures necessary to prepare the firearm for a subsequent discharge. Semi-automatic firearms only discharge once with each trigger actuation, and the trigger must be actuated again to fire another ...
In firearms, a safety or safety catch is a mechanism used to help prevent the accidental discharge of a firearm, helping to ensure safer handling. Safeties generally can be divided into subtypes such as internal safeties (which typically do not receive input from the user) and external safeties (which typically allow the user to give input, for ...
A slamfire is a discharge of a firearm occurring as a cartridge is being loaded into the chamber. Some firearms are designed to slamfire, but the term also describes a malfunction of self-loading firearms. Shooters accustomed to firearms requiring trigger activation for discharge may be unprepared for a slamfire discharge.
Most modern firearms are designed to not be capable of firing when significantly out-of-battery. As such, a firearm that is out-of-battery typically cannot be fired, which is why this is a type of firearm malfunction. A dangerous situation can occur when a chambered round fires when the firearm is out-of-battery (called an out-of-battery ...
