Sig Sauer X-Ray Sights: These sights offer a seamless replacement for your Sig P320’s factory sights, and they are compatible with various Sig pistol models. During installation, it’s essential to match the sight numbers for the front and rear to maintain consistency in your point of impact and point of aim. For example, most 226 and 229 pistols in 9mm or .357 Sig have a #6 front and #8 rear sight. The sights should typically be installed from left to right and removed from right to left, as viewed from the rear of the slide. Before installation, ensure that the dovetail in the slide is clean and lightly lubricated. Additionally, placing the new sights in a plastic bag in the freezer for a while can help shrink them slightly, making installation easier.

Sights for SIG P320 Reviews Comparison

Top 4 Best Sig Sauer P320 Compact Sights Reviews & Complete Guide in 2023

#1. Trijicon SG03 3 Dot Night Sights for SIG P320

My experience with the Trijicon SG03 3 Dot Night Sights for SIG P320 has left me thoroughly impressed. These sights, which I installed on my P229 stainless elite, have significantly enhanced my shooting capabilities. The standout feature is the bright yellow front sight with its tritium insert, which facilitates rapid target acquisition. The large and luminous yellow dot practically guides itself to the target. The rear sight’s big u-notch complements the front sight perfectly, allowing for near-instant alignment. While the rear sight is slightly taller, it boasts a sharp undercut that enables convenient one-handed slide racking, a useful feature.

One of my initial concerns was compatibility, but these sights fit my P320 perfectly, a fact confirmed on Trijicon’s website. The front sight is not only easy to spot but also unobtrusive, striking a balance that enhances target acquisition speed. Even in low-light conditions, the tritium vials shine remarkably bright, ensuring precise aiming. The rear sight’s minimalist design naturally directs your focus to the front sight, which I find highly advantageous. Overall, this upgrade has far exceeded my expectations and has become a staple for all my firearms.

I purchased the Trijicon #8 night sight set for my Sig P228. While removing the original rear sight proved challenging and required a larger hammer and brass punch, installing the new night sights was relatively straightforward. I initiated the installation with a plastic hammer and used a sight pusher tool to finalize their positioning. These sights have proven to be exceptionally effective in low-light conditions, offering clear visibility. For those who engage in a significant amount of daylight shooting outdoors, I’d recommend considering the night sights-fiber optic combo sight set, providing versatility for both daytime and nighttime shooting scenarios.

#2. TRUGLO Tritium Handgun Dark Night Sights

I’ve had the opportunity to install TRUGLO Tritium Handgun Dark Night Sights on various firearm models, ranging from Glocks and CZs to a P320 and most recently on a Mossberg. Through these installations, I’ve found these sights to be incredibly versatile and compatible with a wide range of handguns. If you’re not confident in your sight installation skills, I recommend seeking assistance from a gunsmith or acquiring a sight pusher tool to ensure a proper fit. Personally, I’ve developed effective installation methods that have proven successful without causing any damage to the tritium lamps or dovetails.

For my Mossberg, I specifically opted for the #8 front and #8 rear sights, and they seamlessly integrated with my firearm. Notably, these sights did not alter the point of aim or point of impact, which I meticulously confirmed using a laser bore sight. While I haven’t yet had the chance to put these sights to the test in live-fire scenarios, I intend to provide an update if any unexpected changes occur during actual shooting conditions.

One of the standout features of TRUGLO Tritium Handgun Dark Night Sights is their exceptional brightness and consistent performance across various lighting conditions. They outshine many other manufacturers, including the SIG LIGHT night sights, in terms of brightness, making target acquisition swift and accurate whether transitioning from total darkness to shadows, dusk, or broad daylight. These sights are crafted from high-quality steel, boasting impeccable fit and finish, which enhances their overall durability.

During the installation process, I noticed that the bottom of the TRUGLO #8 front and rear sights align perfectly with the top of the slide, ensuring a snug fit without risking any damage to the slide’s surface. Additionally, I found that the point of aim and point of impact at 16 yards remained consistent compared to the SIG LIGHT NIGHT SIGHTS, underscoring the precision and reliability of TRUGLO’s offerings.

Beyond my Mossberg, I’ve also experienced the benefits of these sights on my FN 509. Despite encountering a minor issue with the set screw length, which required a bit of filing, the TRUGLO Tritium Handgun Dark Night Sights delivered an improved sight picture. The front sight aligned more tightly with the rear u-notch compared to factory irons, enhancing accuracy and target acquisition. Moreover, the tritium illumination remained impressively bright, and I didn’t experience any sight drift even after firing approximately 500 rounds.

In conclusion, I opted for TRUGLO Tritium Handgun Dark Night Sights for my SIG P226, having them professionally installed. These sights offer a clear sight picture and exhibit a bright glow, greatly improving my shooting experience. However, upon closer examination, I noticed that both the front and rear sights extended slightly over the slide, a detail that raised some questions about its necessity. While this doesn’t seem to present immediate issues, it does prompt considerations about the potential for dirt accumulation or snagging on objects in certain situations. Nonetheless, considering the overall cost, including the gunsmithing fee, amounted to around $95, these TRUGLO sights remain a reasonable and valuable choice for enhancing accuracy and visibility during shooting.

#3. Sig Sauer SOX10002 X-Ray 6 Sight

In my pursuit of improving the accuracy and overall performance of my Sig P227 Gen2 SAS, I made the decision to replace the factory Nitron sights with the authentic Sig Sauer SOX10002 X-Ray 6 sights, specifically choosing the #6 front and #8 rear sights. The primary motivation behind this upgrade was to address a persistent issue of approximately 3 to 4-inch low groupings at distances ranging from 25 to 30 yards. Upon receiving the product, I was pleased to find it meticulously packaged and in pristine condition. I took it upon myself to carry out the installation, fully aware that this might take a bit more time compared to professional installation. To facilitate the process, I acquired a sight removal tool.

The removal and subsequent replacement of the rear sight proved to be a straightforward task, thanks to the use of CLP, masking tape to protect the firearm’s finish, and the sight removal tool. Installing the new X-Ray #8 rear sight went just as smoothly. It’s crucial to pay attention to the leading edge, as specified in the manual (located on the right side when viewed in a sight picture). Although the removal of the front sight was uncomplicated, I encountered a noteworthy challenge during the installation of the new #6 front sight, which required a good deal of patience and time. Despite the additional effort invested, I am genuinely satisfied with the results. The new X-Ray sights exceeded my expectations, particularly in terms of brightness. The large neon green front sight greatly enhanced my ability to acquire targets swiftly. In conclusion, I wholeheartedly endorse these sights. However, I do suggest that those less experienced in sight installation might consider professional assistance, which may incur an expense of approximately $80. Opting for genuine Sig parts for the 227s is a dependable choice.

I made the decision to equip both my Sig P226 and P229 with these X-Ray sights, as my recent experience with the standard X-Ray sights on my new Sig P365 left a positive impression. The aesthetics of these sights played a pivotal role in my decision, as they appealed to my visual preferences. It’s worth noting that when selecting these sights, it’s crucial to ensure that the sight numbers for both the front and rear align with those of your existing Sig pistol to maintain consistent point of impact and point of aim. Fortunately, Sig pistol sights are conveniently engraved with identifying numbers. For instance, most 226 and 229 pistols chambered in 9mm or .357 Sig come equipped with a #6 front and #8 rear sight, whereas .40 caliber Sigs generally feature a #8 front/#8 rear sight.

Adhering to the correct installation and removal procedure for these sights is paramount. Typically, these sights are installed from left to right and removed from right to left, as viewed from the rear of the slide. Ensuring that the dovetail in the slide is clean and lightly lubricated prior to installation is crucial to achieving a seamless and precise fit. As a useful tip to streamline the installation process, consider placing the new sights in a plastic baggie in the freezer for a brief period before installation. This slight shrinkage can significantly facilitate the installation process.

#4. Best Suppressor Red Dot Sight for SIG P320

TRIJICON SRO Red Dot Sight

Selecting the best red dot sights for sig p320 can be challenging. The TRIJICON SRO red dot sight is one of the choices for the best suppressor option. 

The RMR/SRO adapter plate for Sig Sauer P320 versions, including the X-Carry, serves as a solution for the first-time fitting problem. Also, the plate is relatively easy to locate.

Trijicon RM06-C-700672 RMR Type 2

Choosing the best night sights for red dot optics can be challenging between the Trijicon SRO and RMR. 

The Trijicon RMR sight is the most formidable small Red dot sight on the market. It is built from aluminum and has a patented design that is reliable with recoil and diverts pressures away from the lens, boosting longevity.

TYPES OF NIGHT SIGHTS

Tritium Night Sights 

Tritium is a radioactive hydrogen isotope occurring naturally or chemically synthesized. If you’re worried about radioactivity, its low energy cannot penetrate your skin.

Because tritium’s energy source is intrinsic, it does not require charging or prior light exposure to function. If you store your pistol in a holster or a nightstand drawer, the tritium sights still shine when you pull it out.

When there is enough ambient light, the glow of tritium is undetectable; therefore, tritium sights appear as ordinary dots throughout the day. The most important thing to remember about tritium sights is that they slowly reduce their effectiveness over time.

Tritium has a half-life of around 12.5 years, making these sights half as brilliant in a little more than a decade. If you acquire a used pistol with fitted tritium sights, you’ll need to change them.

Usage/Pros

Tritium night sights are ideal for defensive and low-light shooting. The broad footprint sight bodies make it simple to locate the front sight. They are also continually lit. 

Cons

Tritium is pricey, translucent in intense light, and the intensity of the glow fades over time (10 to 12 years).

For safety, the sight designs require extra steel to surround the ring of the bulb, making these optics taller and broader than ordinary eyepiece.

Photoluminescent Night Sights

If you understand the dynamics of a glow-in-the-dark watch, the functionality of Photoluminescent night sight is straightforward. Unlike tritium optics, Photoluminescent sights absorb energy from an external light source and subsequently emit light for a while. 

They can last up to 8 hours and charge at varying speeds depending on the light source. Under direct sunlight, they can reach their full capability in 7 minutes; under incandescent light, it would take more than 20 minutes.

Quality versions utilize photoluminescent pigments up to 5x brighter and last longer than Tritium night optics. They are industrial and self-adhesive laminates that you can place on your standard gun sights to create 3-dot or heinie layouts that suit your shooting style.

Usage/Pros

These sights are scratch and water-resistant, designed to perform in the harshest conditions, and are replaceable without damaging your handgun.

Unlike the tritium types, they maintain visibility in all lighting conditions and have improved visibility in bright sunlight.

Cons

Photoluminescent sights are often cheap, but their main disadvantage is obvious: they will not glow if not recently exposed to light.

If you extensively store your handgun holstered away from a light source, its ability to discharge light will be ineffective.

Sig P320 Fiber Optic Sights

As one of the sights for sig p320, the optical fiber is a flexible, transparent glass or a plastic strand. Despite its thin size, it is used to make considerably wider handgun sights that capture and emit light throughout its length. 

Because the rod catches the light and channels it to the rod endpoints, they glow brightly in highly illuminated environments. The longer the rod, the brighter the vision, yet the more fragile it becomes.

Narrow tubes of this material make the gadget very visible even in low-light circumstances. Fiber optic sights come in various colors and are often cheaper than tritium varieties. 

While some assume they are too fragile for a p320 carry handgun, they can resist significant abuse when mounted properly.

Usage/Pros

Fiber rods illuminate effectively in bright light. Their flexibility with several diameter and color possibilities and simplicity in replacement is more than you could ask for at their price range. 

Shortcomings

Fiber Optic Sights require intense light to function even cloud cover can lower the perceived illumination of the sight. The fiber rods are delicate and will not withstand multiple drops or high-intensity recoil.

The rods are simple to replace, but if one breaks while shooting, you must focus entirely on your sight blade.

SIG P320 Co-witness Sights

Firstly, co-witnessing is the combination of sight and the gun’s iron sights. When the red dot on the optic aligns with that on the latter, the two collaborate as co-witness varieties. These varieties offer better precision while providing a contingency option if your primary choice fails.

Absolute and 1/3 versions are the two primary co-witness forms. These approaches are best suited for various situations. What is most efficient and convenient for your shot may determine your most excellent option.

Usage

Absolute:

With this version, the iron sights and red dots are consistent, and the optic is near the bore. You can adjust more efficiently if your eyepiece loses power or if you quickly move from a darker to a brighter place. 

Because you won’t have to realign, you can adapt to changes rapidly.

⅓ co-witness:

Using this option with your sig p320 will benefit from a less cluttered view with greater visibility. This aspect may be your ideal option to see the field and target with utmost clarity, as it helps locate your target quickly.

It may also allow for more natural neck alignment and, thus, less muscle strain.

What To Consider When Selecting a Sight for Your Sig P320

Having gone through some best sight options for a sig p320, you might ask yourself the defining features to look for when purchasing one. 

Below is a list of things your Sig p320 should primarily have for effective performance.

A Rugged Body Material

When you install a sight to your sidearm, it becomes an essential element of your gun. It should therefore be similarly rugged and robust. To ensure durability, make sure the sight is made of steel or metal. Tough night sights feature an aircraft-aluminum-grade material. 

The Ideal Weight for Sig p320 Sight

The sights’ solidity shouldn’t compromise their weight. A lightweight optic of fewer than 2 ounces is ideal with your sig p320. Remember that by mounting a red dot, your weapon will increase in weight significantly.

The Compatibility of the Optic

The Sig Sauer P320 is not a gun compatible with any red dot sight. At times you’ll be required to restructure your weapon. Suppose you do not wish to change or modify your sig p320. Then you may purchase a sight requiring no modification.

Illumination Features

Almost all Sig Sauer p320 front and rear night sight set will provide ideal illumination, especially as a glow-in-the-dark optic. The longevity of the glowing effect is what you should consider. 

As you have discovered in the article, different sights have unique methods of absorbing and emitting light. If your option requires light exposure, expose it to a reliable light source before your subsequent event. 

Battery Specifications for Extended Usage

We advise on Sig Sauer pistols models whose battery specs influence their extended life to give you long service. Longer battery life depends on how frequently you carry your Sig.

A Compact Design

Understanding the sights’ dimensions comes into play as not all optics, despite their quality, will fit your sig p320. Most times, some optics will work but not perfectly.

Choose a sight that is as compact as possible. It will fit precisely on your rifle while saving a lot of room.

The Manufacturer

Rifle scopes and handgun optics brands are increasing daily, and buying a fake product disguised as the best quality option is easier.

The brands discussed above are licensed manufacturers making some of the best optics. 

Essential Functionality Aspects of a Sig P320 Optic

There are three essential functionality features to consider:

1. Glowing green dots: This can be for both front and rear dots, but some, like the TRUGLO variety, have varying front and rear dot colors, which change with the available light. The most important thing is to confirm if the glowing dots work relatively well in low-light contexts. 
2. Durability: Any shooting purpose will demand much from your rifle, thus also punishing your optic. Trijicon night sights(xs sights), especially the RMR, is a good option as it is equipped with an aircraft-grade aluminum grade material to counter recoil and survive in challenging shooting environments.
3. Red dot use: Red dots are described as the premium options. They help in easy sight acquisition, especially for distanced targets in the dark. Trijicon RM06-C-700672 RMR is a reliable option if you’re looking for better visibility and accuracy in low-light environments.

How to Mount a Trijicon SG03 3 Dot Front and Rear Sights for SIG P320

Work On The Gun

Step 1: Safely disassemble the sig p320 and detach the slide. Examine the chamber and remove any bullets you discover. Then, position the barrel safely and pull the trigger to ensure it’s not loaded.

Step 2: Take out the slide’s recoil spring and barrel. Flip the slide over and look for a long, coiled piece of metal that takes up about half of the surface. To loosen and pull the spring out of the slide, apply pressure on the end of the spring. Pull out the barrel, a cylindrical piece of metal that rests beneath the spring.

Step 3: Place the slide sideways on top of a universal workbench block. A stable bench block keeps you from accidentally damaging your p320 when installing the sights.

Rear Sight Set Up

Step 1: Grease the empty dovetail and the new rear sight with rubbing alcohol. Wipe a cotton swab around the interior of the dovetail with rubbing alcohol. Next, wipe your new rear sight’s bottom and sides. Cleaning your equipment of oils and filth provides a snug, secure fit.

Step 2: Back up and partially slide the rear sight into the dovetail. Ensure that the two dots face you as you slide the sight in. If it isn’t going in smoothly, squeeze a drop of grease into the dovetail groove.

Step 3: Tap the rear sight into the dovetail using a hammer. After gently pushing the rear night sight, insert the pistol slide into the device close to its pusher block. Turn the T-handle to shove the new sight into the dovetail’s center.

Step 4: Center your rear optic with the hammer. It doesn’t have to be accurate.

Front Sight Setup

Step 1: Examine the front end of the p320 as you unscrew the front sight with a unique sight tool.

Step 2: Apply a small Locktite to the new screw threads. Insert the replacement screw with your front sight into your front sight tool, pointy side up.

Step 3: Screw the front sight on top of the weapon. Turn the slide over and fasten the screw into the new optic while holding the sight in place. Twist the front sight tool to ensure everything is secure and locked down.

Step 4: Reassemble your p320 with the new optic on. Insert the barrel first, preceded by the recoil spring. Next, align the slide with the gun’s frame and slide it entirely back into place. As the levers lock back, you’ll hear a click sound.

Note: It is essential to wait a day before using the newly assembled sig Sauer p320 with the Trijicon SG03 3 Dot, especially for the lubrication to cure off.
