Today we are going to talk about the tactical lights that will support this bad boy to provide you with exceptional shooting experience whether it is for hunting, home defense, or professional use.

First, we are going to cover the basic parts of a tactical light in the buying guide section. The checklist will help you to jot down the important aspects of any weapon light. Then, we are going to review the top 7 best tactical lights that will fit your Sig Sauer P320 perfectly. Let’s begin, shall we?

Buying Guide For Sig P320 Weapon Lights

Tactical lights have all the basic qualities of any other lights. But there are some unique features such as high brightness output, illumination, and durability, that make it different from other ordinary lights. We have added all the points you need to know about them. That way you would be able to choose the best P320 flashlight.

Brightness Output

The brightness level is an important aspect of tactical lights. However, this level will depend on how and where you want to use the flashlight with your P320 pistol. Almost all weapon lights have brightness output between 500 lumens to 1000 lumens.

For close-range shooting, we would recommend you go for up to 600 lumens of brightness. In case you want to use the light for long-distance hunting then you should go for over 1000 lumens of brightness intensity.


The runtime of a light will depend on certain points such as brightness level, battery quality, and usage. Almost all the lights come with lithium batteries that are well known for long life and saving energy. These batteries can be both rechargeable and disposable.

Normally, light with a high brightness level comes with disposable batteries for high efficiency. The runtime of most flashlights is from 1.5 to 4 hours which can vary with different modes.

Beam Distance

The area coverage of a flashlight can determine its usage. The beam distance or light throw can tell you how far the light can reach. This number depends on the brightness output. Flashlights with high lumen can provide better beam distance.

Some flashlights also have particular optics to cover the surrounding areas so you are always alert in tactical situations. You can also look at the wavelength when buying laser sights. Laser lights with wavelengths between 500 nm to 600 nm are perfect for covering 100 meters.

Light Spectrum

You need to make sure that the light you are choosing has the correct spectrum for a better experience. Most flashlights have white LED technology to give the best sight during nighttime.

But you can find lights that have secondary illumination to cater to particular needs. For instance, you need red illumination for night vision. Similarly, lights can also come with red or green lasers for precise targeting.


After going through all the checklists above you have to check the compatibility of the product. Lights need to be mounted on guns. Therefore, the light you have chosen must fit the barrel of your handgun.

Almost all flashlights have both GL Universal rail and Picatinny rail accessories. For this reason, flashlights are versatile in their adaptability with pistols. In any case, if the light is not compatible with your gun, you can also use mount adaptors to fit it.


To have a long-lasting shelf life, it is essential to make sure the light is strong enough to withstand dust, water, fallout, and recoiling. The aluminum-constructed flashlights are very durable and lightweight.

Besides, you can also check its water resistance rating and impact resistance height to know how much the light can withstand.
