Streamlight TLR 7A Flex - Best Overall

Streamlight TLR 7A Flex is the best compact size handgun light in the market with upgraded control ergonomics from the original model.

The TLR 7A flush fit perfectly on the G19 or the G23 model. It's super light and compact, which takes only 1 CR123A battery (50,000 hours) that can produce up to 500 lumens & 5000 candela with its C4 LED technology.

Streamlight's TIR Optic produces a concentrated beam with optimum peripheral illumination within 30 - 40 yards.

Activation switches are ambidextrous from both sides, the user can activate the light simply by pushing the button.

We highly recommend this product for its size, performance and price, and it's probably the best for G19 for the money.

Viridian X5L Gen 2 - 2nd Best

glock 19 and viridian x5l

The Viridian X5L sits almost flush with the Glock 19, which makes it super compact and quick when drawing in and out of the holster. What we like about the X5L is its durable aluminum body contains a 178 lumen tactical light and laser (Green or Red).

The biggest advantage the X5L has is its tight, slim profile when mounted on the G19 as the first-ever tac light & laser comb that hit the market many years ago that also includes programmable modes, which the user can adjust on the fly by pushing the switch buttons from both sides at the same time to cycle between the modes.

Which includes:

  • Strobes + Constant on laser
  • Constant On (Laser & Light)
  • Momentarily On/Off

The only thing we don't quite like is the screw mounting system, which feels cheap and weak compared to others.

Overall it's a sick pistol laser + light combo system for G19 or G23 that has been around for a very long time, actually the first of its kind on the market.

NOTE: Viridian offers a special holster for X5L sold separately, which can immediately activate the light & laser upon holster draw.

Surefire XH30 - Best Full-Size Duty Light

surefire xh30 weapon light

Why pick this one - The XH30 is newer model of the X300U. It's the go-to duty grade handgun light for the military and law enforcement for close range low light applications.

Wide Spill Light Beam - Not miss a thing from your 9, 12 and 3 O'clock position in the dark with the Surefire TIR lens optimized for wide spill and throw.

Slide Always In Battery - The extra light bezel length sticks out to prevent the slide from getting out of battery during point blank engagement that can save your life.

Mounts Directly To The Rail- Just slap it on the handgun frame rail slot and locks it in place with the new T Slot mount.

Built To Last - The light is built with mil-spec grade aluminum housing to protect the light from sharp recoil impulse, drop and other day to day rough handling without damaging or shifting the electronic components inside the housing unit.

Surefire XC2 Ultra

Img Referenced TFB

The SureFire XC2 is the smallest and most lightweight conceal carry handgun light with an integrated <5mW Class 3R red laser. 

If you're looking for the best weapon light & laser all-in-one package for the Glock 19 or 23, then this is it.

It features a recoil-proof LED that’s focused by a multi-faceted reflector to create our broad 300-lumen MaxVision Beam perfect for illuminating and identifying threats at close range.

It fits flush with the G19 muzzle and weighs just 2.1 ounces, the XC2 is great for everyday concealed-carry.

What makes the XC2 different from other light is the use of just 1 AAA NiMH rechargeable battery (readily available) that lasts just 0.5 hours (~30 mins shorter than other light)

The activation switch sits flush with the G19 trigger guard that works with left and right-handed shooters. It allows the shooter to immediate pushup or down for constant-on, tap/hold for momentarily on-off.

Crimson Trace LL-807 LaserGuard Pro - Lowest Profile Laser

The LL-807 is specific for full size & compact Glocks. It features a 150 lumen LED white light in a single compact unit, which is effective for personal defense without being too dim or too bright.

What we love about this thing is its "under the trigger guard" activation button, which instantly activates the device upon draw without any conscious effort from the shooter at all.

The LL-807 features 4 modes of operation (see below), a Master On/Off Switch, is completely user-installed in moments with no modifications to the gun frame and the laser is user-adjustable for windage and elevation. On just a single CR2 lithium battery, this thing lasts about 2 hours.

Modes of operation include:

  • Laser + Light
  • Laser Only
  • Light Only
  • Laser + Light Strobe

Things To Look For

Why Use A Flush Muzzle Fit Light?

The benefits of a flush fit weapon light on the Glock 19 are:

  • More Compact
  • Faster Out Of The Holster
  • Reduced size profile when concealing

Mount Type

There are many different mount designs out there. Most products will ship with an additional 1913 Picatinny rail and universal mount adapters.

For mounting on the Glock, make sure you pick out the mount that fits the rail slot. The favorite mount type is the one the user can manually tighten the screw even if the rail has been worn out.

Lumen Intensity & Beam Pattern

Generally speaking for home defense use, anything above 500 - 1000 lumens is today's light standards.

A pistol grade light isn't supposed to be a thrower like the ones mounted on rifles. It's primary purpose is to provide enough throw and wide spill for CQB fighting distances to maximize your situational awareness from your 9, 12 and 3 O'clock positions in the dark.

For throw performance, the higher the candela the further the light beam can punch out in the dark, which can also power through ambient lights, fog and other photonic barriers.

Generally anything over 5000 - 13K cd will get the job done. So that will be the Surefire X300U and something like the Inforce Wild 2.

Custom Holster Weapon Light Fit

Kydex holsters is by far the most popular option for most people.

Different profile lights render different holster retention points. So it's important to find a great holster that can retain it without getting too tight or loose.

Only one holster for one light!

We recommend checking out Trex Arm's, Bravo Concealment, Raven and many others for more information.

Activation Switch Design 

Can you reach it easily? Does it have a tactile feel? Does It work well when wearing gloves? Does it work for left & right-handed shooters?

Those are all important aspects of the product you have to test it out before buying. Once you do, you can buy them online for much cheaper & no tax.

Battery Life

Most compact weapon light and laser combo systems use just 1 CR123A to power the whole thing. CR123A batteries are readily available in your local Walmart, Target and even gas stations. Simply pop the old one out and replace it with a fresh battery.
