Streamlight TLR 1 HL

The Streamlight TLR 7A Flex is the best weapon light for a Glock 19 gen 5 and other generations on the market for concealed carry or home defense. It runs on only 1 CR123A that outputs up to 500 lumens & 5000 candela for CQB use.

Muzzle Flush Fit - This tactical light doesn't stick out past the muzzle for better compact size for conceal carry and faster in & out holster draw performance

Maintain Normal Firing Grip - Aim, shoot and activate the light without breaking the grip

Streamlight's TIR Optic - This bright light can see as far as 30 - 40 yards with a balanced concentrated hot spot 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 Streamlight TLR 7 

Strobe Function Available - It's a hidden feature! Activate by Streamlight's TEN TAPS programming

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

    glock 19 with streamlight tlr 1 hl light

    Viridian C5L Gen 2 - Best Light & Laser Combo

    glock 19 with viridian c5l light

    Why put this on your Glock 19? The Viridian C5L tactical light sits almost flush with the Glock 19 muzzle and slightly back behind the muzzle, and it makes it one of the best Glock tactical light and laser combo when drawing in and out of the holster. The light isn't the most impressive, but the green laser is the best for passive aiming if training for speed and accuracy is what you are looking for.

    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.

    • Very compact on Glock 19
    • Visible green laser
    • Front loading battery design
    • Very lightweight laser and light combo for CCW


    • A bit difficult to mount on Glock 19 frame
    • Allen keys required to mount

    Surefire XH30 - Best Duty Light With Strobe

    surefire xh30 on glock 19 pistol

    The Surefire XH30 is a very much a upgraded Surefire X300U pistol light with strobe mode and impact resistant glass. Surefire is the best Surefire light for Glock 19 Gen 3, 4 and 5. 

    surefire xh30 bottom panel
    glock 19 with surefire xh30 TIR beam pattern

    Wide Spill Light Beam - ID targets in low light from 9, 12 and 3 O'clock positions with optimum peripheral illumination in the dark just like the Streamlight TLR 1 HL, but this is the Surefire version that allows the user to switch between 300 or 1000 lumen intensity.

    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

    Strobe Feature Added - Switch between white light or strobe function

    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

    • High ouput: 1000 lumens
    • Peak Candela: 11300 candela
    • Batteries: 2 123A
    • Switch: Ambi toggle

    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.


    • Very low profile for CCW
    • Fast aiming laser


    • Lumen not as bright as others recommended
    • A bit pricy for what it can do

    Olight PL Pro 3 - Best For Training

    olight pl 3 r body construction

    The Olight PL 3 rechargeable is the newest and best Glock 19 light for low light training. If you don't want to constantly buy batteries to review.  The light has a much brighter output and longer battery life thanks to the USB rechargeable feature.

    Increased Lumen & Candela - The PL 3 can lit up a room and positively ID targets further in the dark up to 50 yards

    Ambi Control Ergonomics - Works for both lefties and righties to active constant on, momentary or strobe

    Modlite PL350 - Best Throw Performance

    glock 19 with modlite pl350

    Why give the new MODLITE PL350 a try? - This is MODLITE's first pistol mounted weapon light that can accept Modlite's top 3 light heads: PLHv2, OKW &  PLH 5K. These are brighter light options with varying degrees of throw performance beyond what a normal pistol light can do.

    It's like having a large profile long gun light in a pistol light size configuration.

    Much Higher Candela For Long Distance PID - (PLH5K) Up to 1500 lumens and 29K Candela to lit up targets far away in the distance for personal or home defense (MORE THAN Surefire XH30 & TLR 1 HL)

    Change Light Heads - Swap between PLHv2, OKW (Very powerful LED light) or PLH 5K. All of them feature power LED illumination for different applications

    Flexible Mounted Position - The light body has two flexible slot keys for the M1913 rail

    Very Positive Control - Very positive rocker control switches even when wearing gloves in freezing weather (PHLSTER ARC enhanced WML Switches included to extend the length of the switch for users with short fingers around the trigger guard)

    Better Color Rendition - Up to 5000 Kelvin color temperature for the most neutral/warm light pattern. It's  easier on the eyes in darkness whether it's indoor and outdoor use

    See more PL350 reivew here


    • Much brighter light and throw than other lights for PID
    • 18350 rechargeable battery - long battery life
    • Front loading battery without removing the light
    • Easy toggle switch for one handed operation around the trigger guard


    • Mount key insert feels sloppy 
    • No QD mount
    • Not for CCW because it sticks too far past the muzzle on G19

    Crimson Trace LL-807 LaserGuard Pro - Lowest Profile Laser

    The Crimson Trace 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 and home defense without being too dim or too bright.

    Grip Activation -  Instantly activates the device upon draw without any conscious effort to control the switch at all

    Bladed Shooting Stance - Aim the red accurately with center axis relock technique without aiming down the sight

    The Crimson Trace 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 red 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


    Lumen Intensity & Beam Pattern

    Currently, anything above 500 - 1000 lumens is very good. A balanced throw and spill beam pattern is recommended to maximize situational awareness from the shooter's 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.

    Does Length Of The Light Matter?

    The benefits of a compact size light that sit flush with the muzzle are:

    • More compact
    • Faster speed in & out of the holster
    • Reduced size profile when carry concealed
