Surefire XH30 – Best Overall

Why the XH30 is the best one we picked

• Switching between 300 and 1000 lumens
• Added strobe mode

High lumen light for positive target identification – 1,000 blinding lumens is for lighting up the alleyways in the dark, searching & blind threats, and just use 300 lumens if less brightness is desired.

Increased low light situational awareness – The light beam has a wide coverage on a human size target from the head to the waistband, and be situationally aware of everything in the dark without having to pan the light.

Disoriente threats – The added strobe feature flashes intensively to blind up close threats from making any further bad decisions, but to surrender or retreat

Works great on FLUX DEFENSE MP17 – If you have the PDW accessory kit from Flux Defense, the Surefire fits perfectly on the MP17 module providing this converted PDW P320 with the best weapon light capability

NOTE: If you already have a holster for the X300U, the XH30 will not fit due to the difference on the front lens.

Olight PL Pro Valkyrie – Highest Lumen & Candela

Why this is a great light on P320 – The PL Pro feels very similar to the Surefire X300U and it features USB rechargeable battery design, where the user can save tons of money buying CR123A batteries.

You can check out the X300U and PL Pro comparison on our site.

The light mounts onto the P320 very easily using its QD lever, and if it’s too lose the user can tighten the screw.

Highest Lumen & Candela – The PL Pro has about 1500 lumens and 19600 candela with up to 280 meters of throw in pitch black environment, this is great for home defense and night class training.

The controls on the Olight includes

• constant on
• momentary
• strobe

Can be used on P320 & other long guns – That can be used from both sides and also to be used on long guns.

However, the electronic push button senses how long you have pushed the button, and then it performs the correct function.

This is inferior to the rocker type switch because there is a delay, and you can’t just do a quick tap for momentary-on, and you have to hold it. This slows you down and could potentially affect motor skills during stressful situations.

Streamlight TLR 2 HL G – Best Runner Up

Why pick this one – TLR2 G rail mounted flashlight comes with a (<5mW Class 3R) Green laser that provides fast point and shoot targeting especially in improvised shooting positions.

In addition it comes with a programmable strobe for deterring threats with intense non-lethal light beam.

Best alternative to Surefire X300U – For the money, its the best alternative to a Surefire X400 weapon light for a tactical P320 setup.

What’s great about the TLR2 G for the P320 is the affordable price point and outstanding performance compared to the SureFire X400.

Fast aim with laser – The added powerful green laser pointer allows the shooter to quickly get on target without iron sight alignment. It’s recommended for improvised shooting positions.

Tough secure mount – Being able to mount and detach the light is important to quickly change pistol configuration. The QD screw type mount allows the shooter to mount the light securely and remove very easily

Streamlight TLR8 – Most Reliable Compact Light

Why try a compact light – If you want a compact weapon light for a compact size P320, the TLR8 is a great light and laser combo to buy.

Perfect flush fit – This light mounts flush perfectly on the compact sig p320 RX. It’s super light and compact for popular conceal carry methods without getting bulky

Wide peripheral illumination – Streamlight’s TIR Optic produces a concentrated beam with optimum peripheral illumination; optimized electronics provide regulated intensity.

Light only or laser combo option available – The red laser is the cheaper option built with Class 3R 650 nm, Output <5mW for accurate and fast aiming without a sight picture alignment, which is great for close-range personal defense.

Slim ambi-activation switches – Activation switches are ambidextrous from both sides, the user can activate the light simply by pushing the button. However, no momentary or strobe

We highly recommend this product for its size, performance and price, and it’s probably the best for P320 compact carry for the money.

Surefire XC1 – Lowest Profile

Why try this one – The Surefire XC1B is the smallest weapon light out there. It fits flush with the muzzle on the compact P320, great for concealed carry.

Recoil proof LED – Being able to function shots after shots is important, the improved recoil-proof LED can do just that, and its 300-lumen MaxVision beam is perfect for illuminating and identifying threats at close range.

Improved ruggedness for daily CCW use – Built with lightweight, strong aerospace aluminum hard anodized with a durable Mil-Spec finish, making the XC1-B plenty rugged enough for everyday carry and duty use.

Improved constant-on activation – By tapping either one of the momentary switches (ambi). To turn off, simply tap either one of the momentary switches again.
