Surefire X300U - Best Sig Sauer P320 Light

sig p320 axg surefire x300U
The classic Surefire X300U pistol light outputs the widest beam for CQB, and throws the hot center beam far in the dark for mid range target ID and effective threat control. 

This is one of the best tactical pistol lights for Sig P320 for its field durability, long term positive track record, and tried and true light solution for many pistols on the market.

1000 Lumens - The user can lit up targets in the dark and scan around tight spaces with plenty of light. This allows the user to discern more details in low-light conditions, enabling them to identify potential threats such as a human-sized target from head to waist.

Improving Low Light Situational Awareness  - By using the TIR reflector, the light beam is spread over a long distance, making it possible to detect targets from 5 to 20 yards away. 

Constant On / Momentary - The user can activate the light with gentle forward thumb press for momentary. Extended paddle switch is available for users with short thumb

Olight PL Pro 3 Valkyrie - Best For The Money

sig p320 olight pl pro 3 valkyrie

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 – The High Light Intensity and Candela of this flashlight make it an ideal choice for home defense and night shooting training. With a maximum output of 1300 lumens and 12500 candela, it has a beam distance of 150 meters, allowing you to see much further in the dark.

Adjustable Lighted Mount Locations - Adjustable mounting system can bring the light closer to the trigger guard if needed on the Sig P320

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

The pressure switch controls on the Olight includes

  • constant on
  • momentary
  • strobe

Ambi Control - Operate the light from both sides and also can be used on long guns.
