    A firing pin block is a mechanical block used in semi-automatic firearms and some revolvers that, when at rest, obstructs forward travel of the firing pin, but is linked to the trigger mechanism and clears the obstruction to the pin just before the hammer or striker is released. This prevents the firing pin from striking a chambered cartridge ...

  3. Microstamping - Wikipedia

    en.wikipedia.org/wiki/Microstamping

    The United States National Research Council released a report in 2008 that endorsed the investigation of microstamping as an alternative to ballistic markings.It had concluded that a national database of ballistic markings is unworkable and that there is not enough scientific evidence that, "every gun leaves microscopic marks on bullets and cartridge cases that are unique to that weapon and ...

  4. Firing pin - Wikipedia

    en.wikipedia.org/wiki/Firing_pin

    A firing pin or striker is a part of the firing mechanism of a firearm that impacts the primer in the base of a cartridge and causes it to fire. In firearms terminology, a striker is a particular type of firing pin where a compressed spring acts directly on the firing pin to provide the impact force rather than it being struck by a hammer.

  5. Bolt (firearms) - Wikipedia

    en.wikipedia.org/wiki/Bolt_(firearms)

    The firing pin and extractor are often integral parts of the bolt. The terms " breechblock " and "bolt" are often used interchangeably or without a clear distinction, though usually, a bolt is a type of breechblock that has a nominally circular cross-section.

  6. Forensic firearm examination - Wikipedia

    en.wikipedia.org/wiki/Forensic_firearm_examination

    Advancements in microscopic stamping have led to a push for the inclusion of firing pin microstamping. [32]: 16 The microstamp is etched onto the firing pin and is transferred to the cartridge during the firing process. Each firing pin would have a unique serial number allowing investigators to trace casings found at a crime scene to a known ...

  8. Firearm malfunction - Wikipedia

    en.wikipedia.org/wiki/Firearm_malfunction

    A slamfire is a premature, unintended discharge of a firearm that occurs as a round is being loaded into the chamber, when the bolt "slams" forward (hence the name), as a result of the firing pin having not been retracted into the bolt, or from the firing pin being carried forward by the momentum of returning to battery. Similar to a hammer ...

  9. Hammer (firearms) - Wikipedia

    en.wikipedia.org/wiki/Hammer_(firearms)

    A linear hammer is similar to but differs from a striker in that the hammer is a separate component from the firing pin. [10] When released, a linear hammer, under spring pressure, slides along the bore axis rather than pivoting around a pin placed perpendicular to the bore, as with the more common rotating hammer.
