Streamlight TLR 1 HL - Best Overall

glock 17 with streamlight tlr 1 hl

Why Pros Have TLR 1 On Their G17s? - The Streamlight TLR 1 is used on most law enforcement officer's duty pistol setup. It's by far the most popular duty grade pistol weapon light that offers great illumination capabilities at a good price point.

Easy Toggle Switch - No need to hard press the switch to activate the light. Easy to two handed and one handed operation.

Replaceable Lens Bezel - Saves money just by replacing the bezel instead of the whole light after damage from force on force simunition training.

Strobe Mode Added - Blind threats with fast rate strobe light to gain tactical advantages


  • 1000 Lumens
  • 15000 Candela
  • 2 CR123A Batteries
  • 4.18 oz
  • 3.39 in
  • IPX7

Also check out LAPG XWL - TLR 1 Clone with much more focused throw, but for how affordable the Streamlight TLR 1 HL is now days, we recommend getting the TLR 1 instead of fussing over saving just $40 more.

Surefire XH30 - 2nd Best Duty 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.

Strobe Mode Added - New strobe mode added to blind threats like the TLR 1 HL

Balanced Throw & Spill - You get the hot spot and wide illumination. Make sure to get the XH30 for this feature, not the XH35

Slide Always In Battery - Prevent the slide from getting out of battery during point blank muzzle-to=surface contact engagement to save your life.

Mounts Directly To The Rail- Glock rail key included for a perfect Glock 17 fit. Use it on other pistols as well.

Built To Last - Mil-spec grade aluminum housing protects electronic components inside from sharp recoil impulse, drop, and day to day handling.


  • 1000 Lumens
  • 11300 Candela
  • 2 CR123A Batteries
  • 4.8 oz
  • 3.7 in
  • IPX7

Olight PL Pro - Best For Training

Why Train With Olight? - The PL Pro's USB charging capability makes this light very cost effective for high volume low light training at home, at classes or at the range. It looks like a Surefire X300, but not exactly.

High Lumen - Very powerful illumination just like the ones we have recommended above

QD Lever Mount - GL rail key included, and no tool required to install or to remove

Positive Control - Very positive activation control switch even when wearing gloves

Unlimited Battery - Saves money buying batteries and use the light as much as you want and just charge it via a USB cord

tlr 7 on glock 17

Streamlight TLR 7A Flex is the best compact size handgun light in the market for compact size pistols including the Glock 19, but it also works on the Glock 17. 

Adds Just 2.4 Oz To Your Setup - Only 1 CR123A battery (50,000 hours) that can produce up to 500 lumens & 5000 candela with its C4 LED technology.

See All Around You - See up to 30 - 40 yards in low light and not miss a thing from your 9 - 3 O' clock positions.

Great For CCW - Much smaller light profile for the G17 for carry

Ambi Control - Works For Lefties & Righties

Aim With Laser - Try the TLR8AG with the laser capability


  • 500 Lumens
  • 5000 Candela
  • 1 CR123A Batteries
  • 2.40 oz
  • 2.58 in
  • IPX7'

Things To Look For

Does The Light Bezel Flush With The Muzzle Matter?

The benefits of flush fitting the light bezel to the muzzle are:

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

The benefits of light bezel extends past the muzzle:

  • Keeps muzzle contact free to keep the slide always in battery during contact shoot scenario

For a full size Glock 17, having the light bezel sticking out pass the muzzle isn't a big deal unless you want to conceal it to minimize size.

Mount Type

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

Custom Holster Weapon Light Fit

We recommend checking out Trex Arms, Bravo Concealment, Raven and many others for more products.

Battery Life

Most compact weapon light and laser combo systems use CR123A battery technology.

As newer lights hit the market, the rechargeable ones are very popular so that you can train more, charge it whenever you want, and save more money on batteries.

When it comes to getting more training with the light without burning tons of batteries, use the OLIGHT and then swap it to something like the X300 when for serious use.
