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

Muzzle Flush Fit - Doesn't stick out past the muzzle for better compact size for conceal carry and faster in & out holster performance for G19 or G23 pistols

Only 1 CR123A - Produces up to 500 lumens & 5000 candela with its C4 LED technology.

Streamlight's TIR Optic - See as far as 30 - 40 yards with a balanced concentrated beam with spill to ID targets from your 9 to 3 o'clock positions

Upgraded Switches - Ambidextrous for lefties and righties. Much better light activation ergonomics while shooting on the move than the original TLR7 

We highly recommend this product for its size, performance and price, and it's by far the best for Glock 19 and G19 similar pistols for the money.

Viridian C5L Gen 2 - Best Compact Laser

glock 19 with viridian c5l light

Why put this on your G19? The Viridian C5L sits almost flush with the Glock 19 and slightly back behind the muzzle, and it makes it super compact and quick when drawing in and out of the holster. 

What we like about the Viridian C5L is its beefy aluminum body packed with a tactical light and laser combo (Green or Red).

Great For CCW - The biggest advantage the C5L has is its fearless green laser paired with a wide flood white light for home defense & conceal carry.

Hot Spot Doesn't Blind Laser Dot - 100 lumens doesn't blind the laser pointer, so the user can see both to aim and ID targets in the dark

Strobe Mode Added - Switch between:

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

Overall it's a sick pistol laser + light combo system for G19 / G23 and other sub compact pistols. 

NOTE: Viridian offers a special holster for C5L sold separately, which can immediately activate the light & laser upon holster draw.

Surefire XH30 - Best Full-Size Duty Light

Why pick this one - The XH30 is newer model of the X300U, this time the user can configure the light to operate between 300 or 1000 lumen, and the strobe mode.

Wide Spill Light Beam - ID targets in low light from 9, 12 and 3 O'clock positions in the dark without compromising throw capability.

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 To The Glock Rail Frame- Glock rail key included. Be aware, this light does overhang a bit more past the muzzle

Built To Last - Mil-spec grade aluminum housing protects the core light components from sharp recoil impulse, drop and other day to day rough handling

streamlight tlr 1 hl on g19 pistol

Why People Love This One? - The TLR 1 HL is newer model of the original TLR 1 with increased lumen up to 1000. It's actually more widely used than Surefire X300U for law enforcement duty handguns, and it's much more affordable.

Easier Single Hand Operation - Much easier toggle switch for the finger to reach and operate without much finger pressure

Retained Mount Screw - Mount and de mount the light easily using a coin, shell casing or screw driver

Built In Strobe Mode - Much easier strobe activation, simply double tap the switch without having to reconfigure the light's mode setting like the SF XH30.

Much More Serviceable Than SF X300U - Replaceable light bezel without having to replace the whole light if its damage during force on force training

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. 

This is an all-in-one package for the Glock 19 or 23

Recoil-proof LED - Multi-faceted 300 lumen reflector is perfect for illuminating and identifying threats at close range.

Muzzle Flush Fit - Light doesn't overhang past the muzzle, and it's great for concealed-carry.

Rechargeable - Just 1 AAA NiMH rechargeable battery (readily available) 

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 in & out of the holster
  • Reduced size profile when concealing

Mount Type

For mounting on the Glock 19 frame, make sure you pick out the mount that fits the rail slot.

Most weapon lights on the market today offer a GL specific mount key. 

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.

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.


CR123A batteries are readily available in your local Walmart, Target and even gas stations. Simply pop the old ones out and replace them.
