Streamlight TLR 7 X - Best Overall

glock 19 with streamlight tlr 7 x

I highly recommend the Streamlight TLR 7X for the Glock 19 with its size for low light CQB use. Streamlight has made it compatible with SL-B9 rechargeable battery (Sold separately) so users can save more money buying batteries  

With just one CR123A battery, it shines as bright as 500 lumens and 5000 candela, making it ideal for close-quarters situations.

One of the things I love about it is its Muzzle Flush Fit. The light fits snugly, so it doesn't stick out from the muzzle, which makes it compact for hiding and quick to draw from my holster.

The improved light activation ergonomics when shooting on the move are a significant improvement over the original Streamlight TLR 7. It makes handling the light while in action much smoother and more efficient.

  • High ouput: 500 lumens
  • Peak Candela: 5000 candela
  • Batteries: CR123A or Streamlight SLB9 battery
  • Switch: Ambi toggle
  • Length: 2.51"
  • Weight: 2.39 oz

Streamlight TLR 1 HL - Best Duty Light For The Money

glock 19 with streamlight tlr 1 hl light

I recently tried the Streamlight TLR 1 HL on my Glock 19. This light is seriously bright, way more intense than the TLR 7. It's a full-size light, but what I love about it is how effortlessly it mounts onto the rail. Plus, switching it on is a breeze.

I don't need to apply much pressure at all to reach and operate the switch. And when it comes to mounting or demounting the light, it's a piece of cake. I can use a coin, shell casing, or screwdriver, thanks to the retained mount screw. This is super handy in a variety of situations.

It also comes with a built-in strobe mode, which can be a real advantage in certain scenarios. However, I've noticed that the activation can be a bit too sensitive. If I'm not careful and accidentally double-tap the switch, especially when I'm fumbling, it activates the strobe. This can be a bit of a nuisance, but it's a minor issue compared to the overall performance and convenience of this light.

Viridian C5L Gen 2 - Best Light & Laser Combo


glock 19 gen 5 light

I decided to put the Viridian C5L tactical light on my Glock 19 for a specific reason. It aligns almost perfectly with the Glock 19's muzzle, sitting just slightly behind it. This placement not only looks sleek but also makes it one of the best green laser pointers for the Glock 19.

Now, I'll be honest, the light feature of the C5L might not be the most impressive out there, especially since it's an older model. However, where it really shines is the green laser. It's exceptional for fast aiming. 

Another aspect I appreciate is that the 100 lumens brightness doesn't overpower the laser dot. This means I don't get blinded by the hotspot, allowing for clearer visibility. The added strobe mode is a nice touch too. It offers options like strobes with constant on laser, constant on for both laser and light, and a momentarily on/off feature. These functionalities make it a versatile tool.

Pros

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

Cons

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

Surefire X300 Turbo - Best Duty Thrower

surefire x300 turbo glock 19

The Surefire X300 Turbo is on the top of my list, and finally got my hands on it many years ago. It's an upgrade from the Surefire X300U to have a higher candela light output for long range illumination.

The focused beam is a standout feature. It's like having a rifle light mounted on my Glock 19. What makes it really awesome is the tight focus beam can light up targets behind tree lines and shadow dense areas that a flood light can't.

Overall this light has the same dimension as the Surefire X300U, and it's great for home defense and daily carry.

  • High ouput: 650 lumens
  • Peak Candela: 66000 candela
  • Batteries: 2 123A
  • Switch: Ambi toggle
  • Length: 3.76"
  • Weight: 4.4 oz

Pros

  • As durable as Surefire X300U series
  • Handles extreme weather conditions
  • Long range illumination
  • No dimensional differences from X300U
  • Same ergonomics as X300U

Cons

  • Stiff switches to toggle for gloved users
  • Sticks out too far if without muzzle brake

Olight PL Pro 3 - Best For Training

glock 19 flashlight

I've been using the Olight PL 3 rechargeable light on my Glock 19, and it's been fantastic for my low-light training sessions. The biggest draw for me was not having to constantly buy new batteries. This light is brighter and has a longer battery life, all thanks to its USB rechargeable feature.

One thing that really stands out is the adjustable mount position. The Olight PL 3 comes with a new thumb screw mount, replacing the QD lever to avoid any snag hazards. I love the adjustable mount key that lets me shift the light's position closer or further away from the trigger guard as I need.

In terms of lumens and candela, the PL 3 really lights up a room. I can positively ID targets further in the dark, up to about 50 yards. However, I feel the throw capability hasn't improved much from the PL Pro.

The USB rechargeable battery allows me to use the light as much as I want during training and recharge it anytime, saving me the hassle and cost of constantly buying batteries.

  • High ouput: 1500 lumens
  • Peak Candela: 10200 candela
  • Batteries: USB Rechargeable
  • Switch: Ambi toggle
  • Length: 3.19"
  • Weight: 3.77 oz

Modlite PL350 - Best Versatility

glock 19x light

I have been testing the MODLITE PL350 for the past 2 years, and I must say, it surpasses most standard Glock 19 pistol lights for my needs. The unique selling point of this light is its ability to change light heads for different purposes, offering brighter light options and a throw performance that extends beyond what a typical pistol light can achieve.

For the first time, I've found a light like this for the Glock 19. It's like having a rifle light on a handgun.

The mounting is flexible, too. The light body has two slot keys for the M1913 rail, which is great. But keeping track of two mount keys can be a bit of a hassle.

The control of this flashlight is exceptional. It's equipped with highly responsive rocker control switches. I found them incredibly easy to operate, even when wearing gloves in cold weather. As someone who sometimes struggles to reach the switch due to shorter fingers, or when the flashlight is positioned near the trigger guard, the included PHLSTER ARC enhanced WML Switches were a significant help.

Another aspect I appreciated was the accurate color rendition. I didn't notice any tint when using this light, and the scene color appeared more neutral, without any skewed color perception.

Pros

  • 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

Cons

  • Mount key insert feels sloppy 
  • No QD mount
  • Not for CCW because it sticks too far past the muzzle on Glock 19

Olight PL Turbo - Best Budget Thrower Light

olight turbo glock 19

The Olight PL Turbo on my Glock 19 performs very similar to the Surefire X300 Turbo, and it's a great budget-friendly option for anyone wanting a high candela lights without breaking the bank.

While the Surefire X300 Turbo and the MODLITE PL350 cost over $350, you can get a Olight for way cheaper and even save 10% if you use the link below (Use code: BADASSOPTIC10)

When it comes to lumens and candela, I found that it's very similar to the Surefire X300 Turbo. This light can positively identify targets up to 100 yards away in the dark, which is impressive.

Another aspect I like is the ambi control ergonomics. The design works well for both left-handed and right-handed users, allowing easy activation of constant on, momentary, or strobe modes.

  • High ouput: 800 lumens
  • Peak Candela: ~66300 candela
  • Batteries: 2 CR123A
  • Switch: Ambi toggle
  • Length: 3.53"
  • Weight: 4.48 oz

Pros

  • Much brighter light than Surefire X300T
  • Long range illumination with flood beam
  • Strong battery door latch
  • Aluminum body with new QD screw mount

Cons

  • Candela output drops after a set time
