In order to assist you in finding the best trigger for your pistol, we have put together a list of some of the best SIG P320 triggers that are currently on the market as of this writing. At its core, the SIG P320 is a fire control unit. Basically, it is an AR lower receiver.
Keeping this in mind, you can eliminate the FCU and change it to and from a diversity of different size grip modules, slides, barrels, calibers, thumb safety, and much more. It’s like a game of Legos with many different parts for grown-up adults.
The SIG P320 can be any gun you want it to be. This firearm’s modular nature has, for obvious reasons, given us a huge market for upgrading and tuning this gun. Which can be confusing at times.
We have gathered a few of our favorite SIG P320 trigger upgrades – well, our favorite upgrades – and hit the ground running. Before we get to the best SIG P320 trigger list itself, we will talk about the kinds of P320 triggers you should consider and which features make a great trigger stand out among its peers.
The Reality: Why Bother Upgrading the Trigger?
Some people like to push things forward. Cars, tech, guns, you name it. Whatever you can think of can always be improved, and that includes the P320 SIG Sauer gun. You can take this P320 and make it entirely your own with custom upgrades, or you can think of putting some ease on your finger. The bottom line could be, why not upgrade a weapon from its factory trigger to something you wish it to be?
The Types of SIG P320 Triggers
Before getting to the reviews, there are a few different kinds of triggers in the gun world that are obtainable for the SIG P320. It’s vital to know which type exists so you know exactly which to choose based on your personal needs and preferences. Here are some of the most standard triggers that you need to know about:
The flat trigger is considered to make follow-up shooting really consistent. Their design is not curved like most triggers, and they are made to be much easier to use. Most flat-faced triggers are designed to make the flat-faced trigger more stress-free and reduce the amount of trigger finger fatigue that comes from extended shooting sessions.
Your single-action triggers are easy to use. All you need to do is cock the hammer back and pull its trigger. From there, the method is just to rinse and repeat. The trigger pulls on a single action will be quick and crisp. You probably won’t get too many creeps depending on which is best fitted on the pistol itself.
Double Action Triggers
The double-action triggers will have a much lengthier pull than the single-action triggers. Like the single action, you will need to cock the hammer back. However, the pull will not be as easy compared to its single-action counterpart. In the 1st stage, it will just be a preparation stage for the 2nd stage. It also functions as a safety feature. These are the triggers that are made to avert accidental discharges from happening.
The Criteria: Factors That Make a Great P320 Trigger
There are some structures and characteristics that will make a trigger face stand out much better than its peers. You’ll need to keep a lookout on what they are so you can opt for the right trigger that will function the way you like it to. Here are the characteristics and features that make a brilliant trigger face better than most:
Light Pull Weight
On average, a factory default trigger will have a pull weight of approximately 8 pounds. As a rule of the thumb, the lighter the trigger pull from aftermarket triggers – the better chance you’ll quickly get a trigger travel shot off with thumb safety. So if you hold quick shooting to a high standard, then find yourself a straight trigger upgrade that has a light trigger pull weight.
Yes, know the price range that you are willing to spend on. Many see it as an investment but you have to know your part well. Gun lovers who have a collection of pistols would probably be aware of how an expensive option or a good product/company name doesn’t equate to performance or experience. People must be aware of the difference and spend wisely.
Most trigger kits will be manufactured from high-quality materials. This will definitely make the stock trigger hard-hitting and more resistant to scratches, over travel, scuffs, and other things that may otherwise damage the trigger itself. Most of these triggers will be made from steel and may be anodized for more protection.
Easy Installation Process
If you lack a good volume of gunsmithing skills, you may want to look into finding a drop-in stock trigger for your own use (and benefit). These are the types of triggers that can allow you to install them onto your pistol with great comfort. All it takes is a few minutes of your time and the correct kind of tools for the installation.
