Inforce WML

sig mpx with inforce wml

The Inforce WML is one of our favorites weapon light for its unique ergonomics for multiple weapon platforms including the Sig Sauer MPX.

The ergonomic angled pressure switch allows the shooter to naturally place their thumb over the activation switch while in full control of the handguard while shooting on the move.

The light can produce up to 800 lumens of vibrant concentrated white light plenty high-intensity beam fills your field of view for close to mid-range target identification.

The WML Series light is ultra-compact, durable, and offers three operating modes: 

  • Constant 
  • Momentary
  • Strobe

When not needed, the safety lever can be snapped on to prevent accidential light discharge.

This is the best tactical weapon light for the money & performance for night shoot and CQB home defense. 

Recommend mounting the light on the top rail for C clamp grip users.

Streamlight TLR 8

Image Referenced Omaha Outdoors

The Streamlight TLR 8 is a white light plus red laser combo, mostly used for pistol illumination applications, but we had to bring this up because it was featured in the movie John Wick 3.

The light is extremely small, affordable and great for a 9mm sub gun. The light bulb can illuminate up to 500 lumens with 4300 candela, aka up to 130 meters effective range.

The <5mW Class3R red laser provides long-range & fast CQB targeting when shooting without aiming down the sight.

The light activation buttons arent the most intuitive and easy to operate on the original models, but the NEW Streamlight TLR 8A G comes with more ergonomic switches where the users can easily operate the light while mounted on the handguard or on the flat top rail.


Recommended Mounting Accessories For Sig MPX

The Sig MPX comes with its factory Key Mod rail handguard, therefore getting the right KeyMod adapter for your particular light is important.

The most popular configurations are:

KeyMod to Picatinny

KeyMod to Scout light mount

Angled offset light mount

NOTE: When mounting a laser device to the handguard, please make sure the laser sits as close to the bore as possible & dont lose zero due to handguard wobble.

Pressure Switch

There are many remote pressure switches you can use. If you’re a Surefire Scout user, please use the Surefire SR07 as its the most popular product on the market.

If you’re a Streamlight ProTac HLX please use the Stream light pressure pad.

For dual devices light & laser configuration, please check out our detailed buyers’ guide on our site: Top 6 Tactical Light Remote Control Pressure Switches


Why Add A Weapon Light On The MPX?

Depend on what you use the Sig MPX for… maybe for the most time you dont ever need a tactical weapon light for range use.

But… if you have your MPX rigged for home defense, then you better have some sort of illumination device that helps you identify targets in low light, maximize situational awareness & deter threat with intense non lethal light.

Another usage is for anyone who participates in night time USPSA matches, sometimes the stage isnt well lit or it’s setup so the shooters have to apply their tactical flashlight techniques to beat the course.


How Much Lumens Do You Really Need?

Is 100 lumens enough? How about 500 lumens? How about 1000 lumens?

In general, anything between 120 to 600 lumens is tactically practical for most weapon light related usage.

Another thing most people ignore is the Candela ratings, which we have a full guide on our site breaking down how much lumens you really need in a weapon light.

While most people just guess and buy whatever product that has the best marketing message, hopefully you’re more knowledgeable after reading this.

How Close To Mount The Light Near The Muzzle

When mounting the light flush to the muzzle, it allows the beam pattern to be uninterrupted, which doesn’t cast shadow of parts of the gun.

However, if you mount the light flush to side blast muzzle brake, then you have to periodically cleaning the carbon residue off the light.


Large VS Small Weapon Light

Should you mount a large profile tactical flashlight or low profile light on the Sig MPX?

For full carbine length users, its not a bad idea to use either one because you have alot more rail real estate to mount accessories.

For SBR & Pistol MPX users, getting low profile weapon light is recommended to keep everything compact.

At the end of the day, its all up to your personal preference on what makes you feel comfortable.
