Here are the 5 best Sig P320 light choices. We've purchased all of them and tested them back and forth at the outdoor range in low light for their lumen intensity, candela output, durability, mount style and price are important criteria to help P320 owners make a good purchase decision.

You have a good light when it has a secure mount that prevents it from flying off the gun while firing, remains on during recoil, and offers sufficient brightness to identify targets in the darkness. Once these three crucial aspects are fulfilled, you possess a reliable light.

Surefire X300U - Best Light For Sig P320

best light for sig p320
The renowned Surefire X300U handgun flashlight delivers the broadest light beam perfect for Close Quarters Battle (CQB). It also casts a powerful central beam that reaches far into darkness, aiding in the identification of mid-range targets and managing threats effectively.

With its long-standing reliability, robustness in the field, and a proven track record, it stands out as one of the best tactical lights for the Sig P320. 

1000 Lumens - The user has the ability to illuminate targets in the dark and examine cramped areas with ample light, thereby enabling them to distinguish additional details in low-light situations. Consequently, they can identify potential hazards, such as a target of human size spanning from the head to the waist.

Improving Low Light Situational Awareness  - The TIR reflector spreads the light beam over a long distance, enabling the detection of targets from a range of 5 to 20 yards away.

Constant On / Momentary - If you gently press your thumb forward, you can turn the light on for a short time. There is also a long paddle switch for those who have a shorter thumb.

Olight PL Pro 3 Valkyrie - Best For The Money

The new Olight PL Pro 3 Valkyrie tactical light feels very similar to the original Olight PL Pro Valkyrie rail mounted light, but without the QD lever nor the built in rechargeable battery port.

We picked this light because it's affordable and it features the USB recharging capability for long term training without having to buy batteries.

High Light Intensity & Candela – This flashlight's High Light Intensity and Candela make it perfect for protecting your home and training for shooting at night. It can emit up to 1300 lumens and 12500 candela, enabling you to see farther in the darkness, with a beam distance of 150 meters.

Adjustable Lighted Mount Locations - If necessary, the Sig P320's adjustable mounting system allows the light to be brought closer to the trigger guard.

Built In Strobe Mode - The user can activate the strobe to disorientate the threat up close

For higher candela usage on the Sig Sauer P320, please check out the brand new Olight Valkyrie Turbo LEP - Outputs up to 70K candela for long range PID
