Put simply, a binary trigger is a type of semiautomatic trigger with two firing modes: semiautomatic and binary.<\/span><\/p>\n

Semiautomatic is self-explanatory; it\u2019s the standard trigger type that fires one round from your gun per trigger pull. A <\/span>binary<\/b> trigger<\/strong> setting fires two rounds with each pull of the trigger \u2013 once when you pull the trigger and once when you release the trigger.<\/span><\/p>\n

All binary triggers are classified as trigger modifications. It\u2019s very rare to find a firearm with a binary trigger installed by default. Most binary triggers are selectable. Meaning you can switch between semiautomatic and binary firing modes without being stuck in binary forever.\u00a0<\/span><\/p>\n

How Do Binary Triggers Function?<\/strong><\/h2>\n

To grasp how binary triggers work, let\u2019s go over how semiautomatic standard triggers function.<\/span><\/p>\n

In short, a regular semiautomatic trigger works when a trigger sear drops to release the firearm hammer. The hammer hits the gun\u2019s firing pin, which triggers a small explosion in a loaded cartridge, propelling the round from the barrel of your firearm.<\/span><\/p>\n

After you fire with a semiautomatic trigger, your gun’s hammer re-cocks, and the trigger disconnector holds the trigger back or in a rearward position. As you release the trigger, the disconnector then releases the hammer, allowing the sear to catch the hammer once more.<\/span><\/p>\n

That’s how a semiautomatic trigger operates. A binary trigger, as its name suggests, uses two sears instead of one, allowing for dual trigger movements. When you pull a binary trigger, your hammer re-cocks immediately. The disconnector then grabs the hammer to prevent any automatic firing.<\/span><\/p>\n

But as you release the trigger, the trigger\u2019s secondary sear grabs the hammer again. This second sear drops to release the hammer once more and fire a second round. As you use a binary trigger, you\u2019ll indeed see the firearm hammer snap forward twice in rapid succession (unless you hold off on releasing the trigger for whatever reason).<\/span><\/p>\n

Most quality binary triggers will allow you to switch back to the semiautomatic setting while you are holding the trigger down. This allows you to switch between binary and semiautomatic firing modes \u201cin-between\u201d the binary trigger\u2019s second shot, so to speak.<\/span><\/p>\n

Why Use a Binary Trigger?<\/strong><\/h3>\n

If all binary triggers do is add a secondary shot to the end of your trigger pull, why would anyone bother using them? After all, binary triggers take a lot of practice to get used to and can mess up your established shooting habits.<\/span><\/p>\n

Even though they seem a bit funky, binary triggers can provide several serious benefits or advantages for competitive shooters. In many target shooting competitions, speed and shot placement are the two most important factors when being graded.<\/span><\/p>\n

If you have a binary trigger, you can pull off two shots in rapid succession faster than anyone using a standard semiautomatic trigger. For this reason, only some<\/em> competitions allow them. They provide a flat speed increase for skilled marksmen who can use these triggers competently.<\/span><\/p>\n

In certain home defense situations, binary triggers may also be advantageous. Since home defense or personal defense situations<\/a> are often tense and adrenaline-filled, it can be tough to remember to pull the trigger multiple times to take down a larger opponent.<\/span><\/p>\n

A binary trigger takes thinking out of the equation, allowing you to put two rounds into an attacker immediately. When used with a small, self-defense sidearm, it can literally double its stopping power. Although, it also doubles the recoil.<\/span><\/p>\n

Are Binary Triggers Legal?<\/strong><\/h4>\n

Technically, yes. According to federal law per the Bureau of Alcohol, Tobacco, and Firearms, binary triggers are legal modifications to firearms.<\/span><\/p>\n

But in the United States, there are two sets of laws you have to keep in mind: federal and state laws. States have different opinions on binary triggers, so these modifications are only legal in some states. At the time of this writing, binary triggers are illegal in:<\/span><\/p>\n
