Types of SIG P320 Triggers to Consider

There are a few different types of triggers that are available for the SIG P320. It’s important to know which type exists so you know exactly what to choose based on your personal needs and preferences. Here are some of the most popular triggers that you need to know about:

Flat Triggers

Flat triggers are designed to make follow-up shooting really consistent. Their design is not curved like most triggers, and they are designed to be much easier to use. Most of them are designed to make it more comfortable and reduce the amount of trigger finger fatigue that stems from extended shooting sessions.

Single Action Triggers

Your single-action triggers are simple to use. All you need to do is cock the hammer back and pull the trigger. From there, it’s just rinse and repeat. The trigger pulls on a single action will be short and crisp. You probably won’t get a lot of creeps depending on which trigger is installed on the pistol itself.

Double Action Triggers

The double-action triggers will have a much longer pull than the single-action triggers. Like the single action, you’ll need to cock the hammer back. However, the pull won’t be as easy compared to its single-action counterpart. In the first stage, it will just be a prep for the second stage. It also works as a safety feature. These are the triggers that are designed to prevent accidental discharges from happening. 

What Makes a Great SIG P320 Trigger?

There are some features and characteristics that will make a trigger stand out much better than others. You’ll need to keep an eye out on what they are so you can choose the right trigger that will function the way you want it to. Here are the characteristics and features that make a great trigger better than most:

Light Pull Weight

On average, a factory default trigger will have a pull weight of roughly 8 pounds. As a rule of thumb, the lighter the trigger pull the better chance you’ll quickly get a shot off. So if you hold quick shooting to high importance, find a trigger that has a light pull weight.

Durability

Most triggers will be made from high-quality materials. This will definitely make the trigger tough and more resistant to scratches, scuffs, and other things that might otherwise damage the trigger itself. Most of these triggers will be made from steel and may be anodized for added protection.

Easy to Install

If you lack a good amount of gunsmithing skills, you may want to resort to finding a drop-in trigger for your own use. These are the types of triggers that will allow you to install them onto your pistol with great ease. All it takes is a few minutes of your time and the right kind of tools.

What Recent Buyers Report

Most recent buyers were able to use this trigger without any issue. The installation was quick and easy for most. Once installed, the trigger pull reduction was very noticeable. Even one user said he was completely thrown off by how much lighter it was compared to his previous trigger.

​What Recent Buyers Report

This trigger is by far the best overall in terms of performance. The pull is decent but light enough to make your shots quicker than factory default triggers. In short, it’s a major upgrade compared to what rolled off of the assembly line. The straight design is much different than your regular curved triggers. And that makes useability a lot easier.

​Who Will Use This Most

This will be used by almost anyone that is using a P320. This includes the concealed carry users, casual target shooters, and even those who will use the pistol for a home defense application. Because of its ease of use, it will be best used by those who will waste little to no time pulling the trigger.

What Could Be Improved and Why

A possible improvement would be to lighten the weight of the trigger. This will make it a bit easier for those who are competing in shooting competitions. Yes, it’s lighter than usual but probably won’t be enough for those who want to get an edge on the competition.

Bottom Line

If you want a trigger that is considered one of the best in the business, you’d be insane to pass up on the opportunity to look at the Apex Tactical Action Enhancement Trigger a little closer. While it might not be your average pistol trigger, it works a lot better than any pistol trigger that comes right out of the box.

Pros

  • Easy to Install
  • Super Durable
  • It Allows For Quicker Follow-Up Shots
  • It Doesn’t Wiggle Around After Installation
  • Crisp Trigger Pull, The Pull Weight is Nice and Light

Cons

  • None

What Recent Buyers Report

A lot of users were looking for a trigger that was much lighter in pull weight and more reliable overall, but they didn’t have to look too far. They went straight to the source. The Sig Sauer Adverse trigger was much better overall. The pull weight was light and it was a quick and easy pull that yielded quick shots for most. One user said it was great to use when shooting targets in a timed session.

What Recent Buyers Report

Sometimes, it’s good to get a new trigger straight from the manufacturer themselves. This trigger somehow does a better job and has a better design than the factory default triggers that come with your pistol. Plus, it’s easy to install and doesn’t take too long to switch out your old trigger for a new one.

Who Will Use This Most

This trigger will be for those who want to easily switch out their old trigger with a factory replacement. It’s the kind of trigger that will mostly benefit the concealed carry crowd among most P320 owners. Consider this the better and lighter version of the same trigger you might be using right now.

What Could Be Improved and Why

Despite no obvious cons, we might consider the idea of suggesting a possible inclusion of another accessory that would go along nicely with a factory replacement trigger. We’re thinking a factory replacement safety just in case the original safety on your trigger may not be compatible. This way, you’ll have a trigger safety that’s easy to use and much smoother in switching back and forth.

Bottom Line

If you’re looking for a new trigger and wouldn’t mind a factory replacement, the Sig Sauer Adverse Trigger might be good enough to switch out your underwhelming factory default trigger for something better, stronger, and lighter. Don’t be surprised if the pull weight is much lighter upon initial break-in.

Pros

  • Great For EDC Pistols
  • Fits Most P320 Pistols
  • Delivers Quick Initial and Follow-Up Shots
  • No Tools Needed For Installation, Takes a Few Minutes
  • Pull Weight is Much Lighter Than Factory Default Triggers

Cons

  • Some Fitting May Be Required
  • May Not Fit Some P320 Pistols
  • Might Be a Little Heavy For Competition Purposes

​What Recent Buyers Report

A lot of recent buyers were satisfied to find a trigger that not only was affordable, but really easy to install. Most were able to install it in less than five minutes. Once it was installed, the break-in period didn’t last very long. One user said it was a lot lighter than his previous upgrade trigger. He added that he was kicking himself for not choosing this one sooner.

What Recent Buyers Report

This trigger is probably the simplest trigger to install. Even if no tools, it’s quite impressive. But nonetheless, it delivers a much lighter trigger pull than your default factory triggers. The reduction is instantaneous and quite noticeable even at the beginning. If that isn’t impressive, then we cannot tell you what is.

​Who Will Use This Most

This trigger will likely be used by those who want to waste little to no time installing a trigger. It’s drop it in and go. So it will benefit most shooters from concealed carry shooters and casual target shooters. Regardless, it will be a lot better than your average but disappointing trigger.

​What Could Be Improved and Why

One suggested improvement would be to lighten the trigger pull weight to make it more friendly for competition shooters. One way of doing this is by replacing the springs that will make it a bit lighter and more competition friendly. The more you pull the trigger, the better the spring will handle multiple amounts of pull.

​Bottom Line

If you’re looking for a really good trigger that will be reliable, easy to use, and easy on the bank account the Apex Tactical Advanced Flat Trigger is perhaps the trigger you’ll want to upgrade to. It’s the kind of trigger that will give you the performance that says “you get more than what you’ve paid for”.

Pros

  • Very Crisp Trigger Pull
  • Easy to Install, Takes a Few Minutes
  • Minimal to No Over-Travel Was Reported
  • Pull Weight is Much Lighter Than Most Triggers
  • Excellent For EDC, Target Shooting, and Competition Shooting

Cons

  • None.

What Recent Buyers Report

This trigger was a favorite among most concealed carry pistol owners. They were looking for something that was easy to pull and very comfortable for when they want to use it for extended target practice. One said that he was confident in making much quicker shots if and when he has to in a self-defense situation.

What Recent Buyers Report

This trigger is durable, reliable, and definitely gives you a lot less pull weight. Overall it’s how a trigger should be. Plus, it’s backed by a lifetime warranty by the manufacturer. This has the potential to stick with you for the long run, making it one of the best triggers to have if longevity is one of your top priorities.

Who Will Use This Most

This will be a trigger that will be used across all kinds of different shooter types. Concealed carry shooters, competitive shooters, you name it. It’s the closest thing you can get to a multi-purpose trigger for a P320 pistol. Plus, the pull weight is light enough to get the job done no matter what the application is.

​What Could Be Improved and Why

While there are no obvious cons, we can say that it can use some additional springs so you can install them on the trigger if you want a bit more weight to the trigger pull. Not so much weight, but enough that could be considered “just right” for most users. Sometimes, a pull weight can be too light for some shooters.

Bottom Line

If you want a trigger that is excellent across all kinds of applications, the Grayguns Pelt Sig Sauer Trigger might be exactly what you’re looking for in a flat trigger. A flat trigger is easy to use and definitely gets the job done when you want it to.

Pros

  • Easy to Install

  • Excellent Across All Kinds of Applications
  • Doesn’t Bulk Up or Add Any Additional Weight to the ​Pistol
  • The Trigger Weight is Quite Lighter Than the Average Factory Triggers

Cons

  • Some Have Wanted the Trigger Pull Weight to Be a Little Lighter 

What Recent Buyers Report

A lot of buyers were able to use this trigger with no issues at all. The installation was quick and easy and the break-in was quick. Most were able to get used to the trigger after about 100 rounds in. The pull weight from the start was light but got even lighter as it was used more over time. One user said it was the easiest and lightest trigger he’s used to date.

What Recent Buyers Report

This trigger is made from one of the most dominant brands--Apex Tactical. If you’re familiar with the brand, you know that their triggers are reliable, easy to install, and easy to use. We like it because it has these capabilities to make shooting easier for most P320 users. We never choose a good trigger based on the name alone.

Who Will Use This Most

This trigger will be used by almost anyone who has a P320 pistol. After all, it can fit every single one on Earth. So expect it to be a trigger that can be used by all types of shooters across many applications. Don’t be surprised if it ends up as the “best overall” choice in the future.

What Could Be Improved and Why

Once again, the trigger pull weight could be a little lighter. It’s not too heavy or too light, but even some users will be a little finicky about it. Another alternative would be to include some springs that might allow them to easily switch out one for the other if they want a lighter pull weight.

Bottom Line

If you’re a fan of the Apex Tactical brand and want a trigger that will be useful for any P320 pistol out there, the Advanced Curved Trigger might just be your cup of coffee. You can call it the most universal trigger for the pistol itself if you so wish.

What Recent Buyers Report

The trigger kit comes with your choice of either a curved design or an enhanced design. You can choose based on your own personal preferences or needs. Regardless, you still have a trigger that has a pretty good pull weight for you to work with. Aside from that, it’s so easy to assemble a newbie can do it.

Who Will Use This Most

This trigger kit is perfect for beginners starting out with the P320 pistol. It will also be used by those who have no gunsmithing skills and want something that will be easy to assemble. Once assembled, they can take pride in knowing they’ve assembled a light and simple to use trigger. As for applications, it’s pretty much across the board.

What Could Be Improved and Why

One possible improvement could be to make sure that the break-in would be much quicker. It might be a little frustrating for the new users. The sooner they can break it in, the better off they’ll be.

​Bottom Line

If you want a bit of a challenge, a trigger assembly kit could be what you’re looking for. Once you put together this Apex Tactical trigger, you’ll be dying to install it right in your pistol and be ready to take it for a test drive. Once you get used to it, you won’t be able to stop relying on it.

Perks of Getting a New Trigger

When you upgrade to a new trigger, you’ll get to enjoy all the benefits that you may not find in a factory default. Of course, it comes down to finding the trigger you want for your own pistol. Once you find one, here’s what you’ll get to enjoy:

Lighter Pull Weight

Of course, we all want a lighter pull weight. That equals to something much better: quickly getting off your shots. In most shooting applications, timing is everything. The quicker you pull the trigger, the better you can knock down your targets in the right place at the right time.

Better Safety

This usually applies to your double-stage triggers. These kinds of triggers make it hard for the pistol to accidentally fire. But just because you have these triggers installed doesn’t mean you have to be complacent. Always make sure the safety is on while you’re not using the pistol itself. 

Better Ergonomics

Trigger finger fatigue has become more of an issue over the years. Especially when more shooters are spending more time at the range and putting in the time to tune up their shooting ability. One of the reasons is due to heavy trigger pull weight. Another is the design itself. A mix of lighter pull weight and an ergonomically friendly design will make trigger finger fatigue non-existent.

How to Install a SIG P320 Trigger

Installing a P320 trigger can be easy or challenging. But if you need a step-by-step guide on how to get it done, here it is. Before you get started, it’s important to check to see if the pistol is clear and unloaded. That means the mag well and the chamber should both be empty. Once you have the all-clear, you can move to the first step:

If disassembled, first install the trigger spring and the hammer on the side of the housing.

Install the trigger by attaching it to the housing itself. Most of the time, the trigger attachment pin should snap through the hole. Make sure the trigger and the hammer are connected. Likewise, check to see if the pins and holes are connected in the appropriate places. Be sure to test it out by pulling on it a few times.

Add the trigger assembly into the pistol’s lower half of the receiver once everything looks good. Do a final check. At this point, you’re done.

Conclusion

The best SIG P320 trigger is out there. It’s important for you to find one that has a smooth trigger pull and delivers a smooth and reliable performance like nothing else. Whether you conceal carry or use a pistol just to shoot targets with, the trigger is one of the most important accessories of your pistol. Choose one that is the best in quality and performance and you’ll have one that will last you a long time.
