Best FN 509 Upgrades: Tackling Tougher Targets

Let me start by saying that the FN 509 is a fantastic weapon! It’s dependable, accurate, and has an excellent trigger.

However, any firearm can be improved, and upgrading your FN 509 can make it even better. Consider updating the sights to something with better visibility or a more precise aiming point, for example. Consider adding a laser or light accessory to help with low-light shooting scenarios.

There are also several improvements that can improve the ergonomics of the FN 509. For example, you may use grip tape or stippling to strengthen your grip and lessen recoil. To improve your accuracy and control, you might also choose a different style of trigger, such as a flat face or adjustable trigger.

So, I’ve written about all the changes you can make to this FN 509 pistol and how they can help you shoot better. Then, without further ado, let’s get to the good stuff.

FN 509 Trigger Upgrade

Let’s start with the basics and talk about how this 509 handgun’s trigger can be made better. Don’t mistake me. There is no need to change the signal that is already there. It is a pistol that has everything you could want on it. Since the trigger has a pull weight of between 5.5 and 7 pounds, nothing major is wrong with it.

Then you might not understand why I say you should upgrade the trigger. Well, if it’s even possible, I’d like to make it even better. So, I went looking for a trigger kit that would both make the trigger pull longer and shorten the total distance the trigger could move. Please let me tell you about this product.

1. Apex Tactical Action Enhancement FN 509 Trigger Kit

Apex Tactical Action Enhancement FN 509 Trigger Kit

Many good reasons can be given for changing your FN 509’s stock trigger with one from the Apex Action Enhancement Kit.

First of all, this kit makes it easy to change the factory polymer trigger, trigger bar, and sear. You don’t have to do any complicated gunsmithing.

The trigger pulls weight of this kit has been reduced to about 5.5 pounds thanks to a patent-pending design. This is much lighter than the original trigger and lets you shoot more quickly and with more accuracy.

It also shortens the pre-travel, over-travel, total trigger travel, and trigger reset distances to make it easier and more consistent for the shooter to handle the gun.

The flat-faced design of the trigger lets you handle it better and shoot more accurately. The rotating safety, which is in the middle of the gun, keeps it just as safe as when it left the factory.

This kit was made for the FN 509 line of pistols, which includes the new FN 509 Midsize, so it fits your gun perfectly. Keep in mind that it doesn’t work with the FNS and FNS Compact versions.

FN 509 Grip Upgrade

You might also want to improve the grip on your FN 509.

Think about how important it is to hold your gun in a safe and secure way. If you have a good hold on your gun, you may be able to shoot more accurately and with less felt force. Also, putting a new grip on your firearm is a great way to make it your own.

Trust me, a good grip is the key to improving your aim, controlling recoil, and feeling more comfortable while shooting.

So, I think you should get some Talon grips. There are three different kinds, so you can pick the one that feels most natural in your palm. So go ahead and get a better grip on your gun and get ready to shoot like a pro!

1. TALON GRIPS for FN 509 Midsize

Talon Grips for FN 509 Midsize

The grip of a firearm is crucial to one’s ability to hold and control the weapon. Having a grip that is comfortable and safe can help you shoot more accurately and better in general.

The TALON Grips are a popular improvement for a number of reasons. No matter how moist or sweaty your hands are, you can hold on to these grips better because they have a feel that doesn’t slip. The TALON Grips’ rubber-like texture is a good mix between comfort and control, which can make shooting easier and less tiring.

Also, they are easy to put on because you don’t need any special tools or glue. The grips are cut to fit the FN 509 Midsize perfectly, so they won’t get in the way of how the gun works.

Overall, adding them to your FN 509 grip can be a good idea if you want to improve your control, ease, and accuracy.

FN 509 Optical Sight

I’d be happy to tell you some reasons why adding an Optical Sight to your FN 509 is a good idea.

Optical sights are better than standard iron sights in a number of ways. One of the most important perks is that it helps people be more accurate. With an Optical Sight, you can aim more accurately and get a better picture of what you’re looking at. This can lead to tighter shot groups and more hits on target.

Let’s take a look at the FN 509 Optical Sight’s zoom and field of view. For example, the Trijicon RMR Type 2 has a magnification of 1x and an objective lens width of 22mm, which gives it a wide field of view of 16.2m at 100m. Let’s see some attractions now.

1. Trijicon RM06-C-700672 RMR Type 2 Adjustable LED Sight

Trijicon RMR Type 2 3.25 MOA Adjustable LED Red Dot Sight

This sight has a red dot pattern with 3.25 MOA, which means the dot is small and accurate. This is a great way to quickly find your target and make more accurate shots from farther away. This sight is the best when it comes to how well it works.

The RMR Type 2 is made to work well in hard situations. It’s made of strong materials that can take recoil and impact, and it’s waterproof up to 20 meters. This makes it a great choice for both long-range shooting and defensive situations where you need a reliable sight that won’t let you down.

Another great thing about the sight is that the brightness of the LEDs can be changed. You can easily change how bright the dot is to fit the lighting around you. This is important for keeping your sight picture clear and easy to see.

At a brightness setting of 4 out of 8, its battery can last for up to four years of continuous use, which is pretty amazing. That means you won’t have to worry about changing batteries all the time, which can be a pain and stop you from shooting.

Overall, the sight is a great way to upgrade your FN 509. It works well, is accurate, lasts a long time, and has a long power life.

2. Leupold DeltaPoint Pro Reflex Sight

Leupold DeltaPoint Pro Reflex Sight

I think you should go with the Leupold DeltaPoint Pro Reflex Sight.

First of all, the DeltaPoint Pro is great for reducing reacquisition time. This means that you can find your target quickly and correctly for follow-up shots. This is because the aspheric lens gives you a wide field of view and good image quality, so you can see your goal clearly and precisely.

Its patented Motion Sensor Technology is one of its best features. When the sight senses movement, it instantly turns on the light. This is helpful in tactical situations where you need to keep a low profile because it makes your light signal smaller.

It has a spring-activated battery section that can be opened without a tool. This makes it quick and easy to change the battery. And you don’t have to worry about water damaging the sight because it has a waterproof grade of 66 feet, which is the best in the business.

In short, this Sight is a great upgrade for your FN 509. It has features like Motion Sensor Technology, a tool-free battery compartment, and better picture quality that make it stand out.

FN 509 Tactical Light/Laser

The FN 509 can be used with accessories like tactical lights and laser/light packs. If you want to shoot better at night, a weapon light or laser will help. It will also make sure that You know exactly what’s going on at all times.

I like tactical lights because it helps me protect myself. It looks great with your FN 509 pistol, which you keep in your home safe. If you want an FN 509 light, I can give you two more choices. Let’s see what kinds of services they offer.

1. Streamlight 69265 TLR-2 HL G High Lumen Rail Mounted Tactical Light

Streamlight 69265 TLR-2 HL G Rail Mounted Tactical Light

This light is very bright, with a high lumen power that can light up even the darkest places. This can be very important in self-defense situations where you need to quickly and correctly spot possible threats.

It is bright, and it also has a green pointing laser, which can be a huge help in low-light situations. The green laser is more visible than the red one and can help you quickly and accurately target your weapon.

Another great thing about this tactical light is that it can be mounted straight on the rail of your FN 509. This makes it simple to put on and take off, and it won’t add much weight or size to your gun.

Lastly, it comes from a well-known company that is known for making high-quality, long-lasting combat lights. You can be sure that this light will work well in tough situations and last for many years.

I think that adding the light is a great idea, and you should definitely think about it if you want to improve the performance of your gun and your own safety.

2. Kiarswe 500 Lumens Red Green Laser Light Combo

Kiarswe 500 Lumens Red Green Laser Light Combo

I think it’s a good idea to add a tactical light, and if you want something even more useful, a red and green laser light mix could be just what you need.

Here’s why I think you should:

The 500 lumens make it much brighter than the normal FN 509, which doesn’t have any light. This will make it much easier to see in low light, which could save your life if you need to defend yourself.

But the red-green laser light mix is different because it can make a laser beam that is easy to see in either red or green. This can help you aim and hit your target, especially when you’re under a lot of pressure and need to shoot quickly and accurately.

It’s also nice that it can be charged by USB, so there is no need to load up on batteries or worry about running out of charge when things get sticky. And because it can’t be damaged by shocks, it won’t lose its zero when you fire your gun.

Overall, I think that putting a red-and-green laser light combo on your FN 509 could be a good idea if you want to improve your shooting aim and performance as a whole.

FN 509 Barrel Upgrade

I believe that would be a fantastic idea to add a barrel as the next change we make to the FN. You now know how important threaded barrels are when it comes to fitting the right type of muzzle brake or compensator. Because of this, the threading system in the barrel of your pistol must be of good quality.

The FN 509 and 509c are made for the 9mm Luger cartridge, the 1/2 x 28 thread size can be used with them. Because of this, I personally like the Apex tactical 9mm 12-28 threaded barrel for my gun.

1. Apex Tactical Specialties 105072 Apex Grade 9mm Barrel

Apex Tactical Specialties 105072 Apex Grade 9mm Barrel

First of all, updating your gun can make it work better and shoot more accurately. The barrel is made to make the gun more accurate and easier to shoot.

It is built of high-quality materials and has a black melonite finish, which can help it survive longer and smash less easily.

Also, the barrel has been precisely machined to tighter tolerances than the stock barrel, which can lead to better accuracy and stability.

Overall, adding the barrel to your FN 509 can improve its accuracy, make it easier to shoot, and make it last longer.

FN 509 Compensator

First of all, a compensator will make your gun easier to control and shoot more effectively by reducing the recoil. This is important if you plan to use your FN 509 for self-defense or in a shooting competition.

Another good thing about a compensator is that it makes the muzzle rise less. This means that your gun will stay more level and it will be easier to stay on target between shots. And who doesn’t want to look like a total badass at the range?

Also, adding a compensator to your FN 509 is a quick and inexpensive method of it works better without having to buy a whole new gun. It’s kind of like giving your gun a little extra coolness. Let me show you one.

1. PMM FN 509 Compact Tactical JTTC Compensator

PMM FN 509 Compact Tactical JTTC Compensator

The JTTC is made of 7075 Aluminium and finished with a type 3 class 2 hard coat anodize, so you know it’s tough and long-lasting. Plus, it’s made to mount like a muzzle device on a gun, so you don’t have to mess with any set screws.

One of the coolest things about this is that it has a design that holds the compensator in place. This means that even if it comes loose, it won’t fall off or stop your gun from working. You can’t ignore such a big safety factor.

The best part is that the JTTC is made to fit FN factory threaded barrels (1/2 x 28), but it will also fit other barrels with the same threads (though the gap may be different). Plus, this technology has been improved since PMM’s X-Comp gun, so you know you’re getting a high-quality product.

So, if you want to take your FN 509 to the next level, get the compensator. You won’t regret it!


Even though the FN 509 is already a great gun, it can be made even better by adding new features. Upgrading the gun with things like better sights, a laser or light, or changes to the grip and trigger can make it much easier to aim, control, and use.

Upgrading your FN 509 can make it much more fun to shoot. The Apex Tactical Action Enhancement Trigger Kit makes it easy to switch out the trigger, trigger bar, and sear, which reduces the weight of the pull and makes it easier to hold.

TALON Grips have a soft rubber grip that can help you have better control and aim. Adding an optical sight like the Trijicon RMR Type 2 Adjustable LED Sight can help hunters hit their targets more accurately and see them better.

In conclusion, the FN 509 is a great gun right out of the box, but it can always be made better. By upgrading your FN 509, you can make it work better and make it an overall better gun. With these improvements, your FN 509 can become an even better gun that you can count on for years to come.
