The Surefire XH30 is basically a X300U with strobe feature. It's the go-to duty grade Glock 17 light for all indoor low light applications.

Slide Always In Battery - The light bezel sticks out past the muzzle prevents the slide from getting out of battery if it makes contact with something

Strobe Mode Added - Adjustable strobe mode feature added

Balanced Throw & Spill - See far and close up in the dark. 

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 field handling.

  • Easy to mount and demount
  • Strobe mode added that X300U doesn't feature


  • Stiff control switches
  • Doesn't fit existing X300U holster
  • Slightly pricier than TLR 1

Surefire X300 Turbo - Best Thrower 

glock 17 surefire x300 turbo

The new Surefire X300 Turbo doesn't replace the original X300U because the Turbo version is specifically designed for long range illumination use, and the X300U still offers wider light beam spill for indoor use.

The Turbo version features just 650 lumens, but reliable 66000 candela output to lit up targets as far as 100 meters to properly target ID without guess the target's silhouette.

The over all light body is literally the same as X300U, so all existing Glock 17 light bearing holsters for the X300U will work with the X300 Turbo.

glock 17 gen 5 flashlight

Streamlight TLR 7A is the best light for Glock 17 Gen 5 [All generations] on the market so far. It doesn't stick out past the barrel and it tucks in nice for concealed carry.

Adds 2.4 Oz - It's super light weight for compact Glock 17, but it also works on the Glock 17 for concealed carry.

Bright Light Beam  - It uses only 1 CR123A battery that can produce up to 500 lumens & 5000 candela with its C4 LED technology to see all around you.

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 daily carry

Responsive Ambi Control - Works For Lefties & Righties

(Sold Separately ) Laser - Try the TLR8AG with the laser aiming capability as best Glock 17 light laser combo setup


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