The Definition of Matchlock
An early system of ignition for muzzle-loading firearms where a priming charge is loaded into a flashpan with a separate,
manually-operated cover. To fire, the cover is opened and then a slowly smoldering wick, held in the nose of the curved arm,
is lowered by means of a lever (precursor to a trigger) to ignite a priming charge which then ignites
the main propellant charge inside the barrel.
A black powder muzzleloading firearm action which relies upon a serpentine or S-shaped piece of metal to hold a smoldering match.
By pressing the lower end of the serpentine,
the upper end holding the burning match contacts the priming powder in the pan.

A semi-automatic firearm whose breechblock and barrel are not mechanically locked together when fired.
In such case the breechblock immediately begins to separate from the barrel upon firing.
Blowback is used in comparatively low powered weapons, in which inertia of the breechblock, and cartridge wall adhesion against the chamber,
are sufficient enough to retard opening until breech gas pressures have fallen to a safe level.
A type of reflector (reflex) sight for firearms that gives the uses a red light-emitting diode as a reticle to create an aimpoint.

reducing parallax between the line of sight and the line of the bore and increasing the range of
distances for which the scope may be reliably sighted-in.

Both arms are stretched almost equally forward with the gun centered forward.
The knees are straight or only slightly flexed, and the entire body is upright and parallel to the target.
This is an acceptable range stance provided recoil control is not an issue and you don't need to make rapid follow-up shots.
However, if you are practicing for self-defense, you will probably want to use the Modern Isosceles stance stance instead.
To jerk a firearm off target inadvertently in the instant of firing in timid anticipation of recoil. Commonly caused by learning to shoot with a gun more powerful then they are ready for.
