When user releases the trigger, and it travels to its resting position. On semiauto firearms the movement eventually passes by reset position where trigger-disconnector mechanism resets itself to its resting state, in which pulling the trigger releases the sear. The reset event does not occur in double action firearms and in full auto firearms.
Other examples:
If the striker or hammer fail to discharge the cartridge, the trigger may be pulled again and will operate as a double-action only (DAO) until the cartridge discharges or the malfunction is cleared. This allows the operator to attempt a second time to fire a cartridge after a misfire malfunction, as opposed to a single-action, in which the only thing to do if a round fails to fire is to rack the slide, clearing the round and recocking the hammer. The Taurus PT 24/7 Pro pistol (not to be confused with the first-generation 24/7 which was a traditional pre-set) offered this feature starting in 2006.

Frequently Asked Questions about Hair-Trigger Alert.

Opinion: Here’s a new California tax that could prevent gun violence
The word may also be used to describe a switch that initiates the operation of other non-shooting devices such as a trap, a power tool, or a quick release. A small amount of energy applied to the trigger leads to the release of much more energy. Removing US land-based missiles from hair-trigger alert would immediately reduce these risks. It would also encourage reciprocity from Russia, increasing our safety further. And because the United States deploys missiles on submarines—which are invulnerable to attack—we would maintain a nuclear deterrent against any first strike. The United States no longer keeps its bombers armed and ready to take off.

The firing pin/striker then collides into the cartridge primer positioned ahead of it, which contains shock-sensitive compounds (e.g., lead styphnate) that sparks to ignite the propellant powder within the cartridge case and thus discharges the projectile. The trapping interface between the trigger and the hammer/striker is typically referred to as the sear surface. Variable mechanisms will have this surface directly on the trigger and hammer or have separate sears or other connecting parts. This is why back in the service-revolver days, so many police departments (such as LAPD, NYPD, Miami, Montreal) modified their service revolvers to double action only.
L.A. County offers free gun locks in an effort to decrease firearm violence
If the user uses their thumb to pull the hammer to the back, but does not press the trigger, the mechanism will lock the hammer in the cocked position until the trigger is pressed, just like a single action. Firing in double-action mode allows a quicker initiation of fire, but compromised by having a longer, heavier trigger pull, which can affect accuracy compared to the lighter, shorter trigger pull of a single-action fire. Single-action triggers with manually cocked external hammers lasted a while longer in some break-action shotguns and in dangerous game rifles, where the hunter did not want to rely on an unnecessarily complex or fragile weapon. In modern usage, the terms "single-action" and "double-action" almost always refer to handguns, as few (if any) long guns feature double-action triggers. While a "single-action" revolver or semi-automatic pistol must always be cocked prior to firing (either manually or by the operation of the weapon), most "double-action" handguns are capable of firing in both single- and double-action modes.
Intermittent Explosive Disorder is the Real Life Trope Maker for this trope. It can also manifest as a symptom of other disorders, including Bipolar Disorder, Borderline Personality Disorder, and even Attention Deficit Hyperactivity Disorder. Sometimes, the character is this way because they're generally irritable and misanthropic — they don't really like anyone they deal with.
These examples are programmatically compiled from various online sources to illustrate current usage of the word 'hair-trigger.' Any opinions expressed in the examples do not represent those of Merriam-Webster or its editors. Seeing him determined both to fight and to choose fire-arms, Dumas recommended him at least not to use the hair-trigger pistol. Jason picked his words slowly, wondering if this savage shared the same hair-trigger temper as the city dwellers.
Self Defense: When A Trigger Upgrade Becomes A “Hair Trigger”
Therapy is considered the front-line treatment for all BFRBs, including trich. Cognitive behavioral therapy—either on its own or combined with a specific type known as habit reversal training (HRT)—is often the approach of choice, as it targets the thoughts, emotions, and habit cycles that lead to pulling behaviors. Other kinds of therapy such as ACT and dialectical behavioral therapy (DBT) have also shown promise, especially when combined with HRT. While no treatment has been found to be universally effective, some show great promise and may deliver lasting relief. Cognitive behavioral therapy (CBT), coupled with habit reversal training (HRT), is currently thought to be the most effective approach for treating TTM. Researchers have found that individuals who are reluctant to seek conventional treatment may benefit from Internet-based interventions or support groups.
GLOCK is adamant that one of their pistols, used for service or self-defense, has no less than a 5.5-pound pull. Between legal fees and settlement, the department paid out nearly half a million dollars. We proudly sell guns from the finest manufacturers in the world, and we are continually looking for new lines and innovative products.
To that end, Los Angeles County public health officials announced that the county is offering free gun safety locks to residents. Designed for use on unloaded weapons, gun locks cover the trigger and require a key or combination to open. A double-crescent trigger provides select fire capability without the need for a fire mode selector switch. Pressing the upper segment of the trigger produced semi-automatic fire, while holding the lower segment of the trigger produced fully automatic fire. Though considered innovative at the time, the feature was eliminated on most firearms due to its complexity. Examples include MG 34, Kg m/40 light machine gun, M1946 Sieg automatic rifle, and Star Model Z-70.
This can come from an unintended discharge, but what a lot of people miss in the gun world is, it can also come from a false allegation of a negligent discharge. Characters with a hair-trigger temper are generally grumpy to everybody, but they usually have a favorite victim for their rampages — often a Naïve Newcomer who doesn't understand how they keep managing to offend the guy. This can be harmful to the victim's health — while heroic characters with a Hair-Trigger Temper generally restrain themselves to verbal abuse, Anti Villainous ones can get physically violent, and out-and-out villainous ones may even kill people for annoying them. A character with a Hair-Trigger Temper flies into a rage at the slightest provocation. Masters of Disproportionate Retribution, they react explosively to the slightest annoyance. Unlike someone with a Berserk Button, who is generally calm until a specific button is pressed, characters with a hair-trigger temper can be set off by nearly anything.
Clearing a malfunction also usually involves retracting the slide following the "tap rack bang" procedure. Double-action triggers provide the ability to fire the gun whether the hammer is cocked or uncocked. This feature is desirable for military, police, or self-defense pistols. The primary disadvantage of any double-action trigger is the extra length the trigger must be pulled and the extra weight required to overcome the spring tension of the hammer or striker.
One other disadvantage is the difference between the first double-action pull and subsequent single-action pulls. A double-action trigger, also known as double-action only (DAO) to prevent confusion with the more common hybrid DA/SA designs, is a trigger that must perform the double function of both cocking and releasing the hammer/striker. Firearms use triggers to initiate the firing of a cartridge seated within the gun barrel chamber. There are two primary types of striking mechanisms – hammer and striker. A hammer is a pivoting metallic component subjected to spring tension so when released will swing forward to strike a firing pin like a mallet hitting a punch/chisel, which then relays the hammer impulse by moving forward rapidly along its longitudinal axis. A striker is essentially a firing pin directly loaded to a spring, eliminating the need to be struck by a separate hammer.
Characters with a Napoleon Complex are usually known for having a Hair-Trigger Temper. In comparison to the "avoid the Big Red Button" approach with someone with a Berserk Button, conversation with someone like this is like trying to navigate a minefield without a metal detector. You know the danger is there, but you have no clue exactly where it is. At worst, they're a surly, dangerous, ticking time bomb, ready to go off without so much as a warning. The very act of trying to talk to them might be enough to set them off. And even just trying to stay away from them won't necessarily help; they're likely to take being ignored or avoided as a deliberate snub, and...
