Streamlight TLR 1 HL - Best Overall
The Streamlight TLR 1 is most common for law enforcement officer's duty Glock 17 TLR 1 light setup. It's by far the most popular Glock 17 light that offers great illumination capabilities at a good price point.
Easy and Tactile Toggle Switches - No need to hard press the switch to activate the light even in cold freezing weather with or without gloves
Replaceable Lens Bezel - Saves you money just by replacing the bezel instead of the whole light after force on force simunition training damage.
Strobe Mode Added - Blind threats with fast rate strobe light to gain tactical advantages
Features:
- 1000 Lumens
- 15000 Candela
- 2 CR123A Batteries
- 4.18 oz
- 3.39 in
- IPX7
Pros
- Very affordable
- Duty grade light
- High lumen & candela output
- Easy to mount and demount
- Easy to toggle switches for one handed use
Cons
- So many mount keys provided, may lose them
- Still runs on 2 CR123A batteries
Surefire XH30 - 2nd Best Duty Light
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.
Pros
- Duty grade light
- Very wide flood beam
- Easy to mount and demount
- Strobe mode added that X300U doesn't feature
Cons
- Stiff control switches
- Doesn't fit existing X300U holster
- Slightly pricier than TLR 1
Surefire X300 Turbo - Best Thrower
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.
Olight PL 3 - Best Battery Life
The new Olight PL 3's USB charging capability makes this light very cost effective for high volume low light training at home, at classes or at the range.
High Lumen - Very powerful illumination just like the ones we have recommended above
New Thumb Screw Mount - No more sharp QD lever that takes up space
Positive Control - Very positive activation control switch even when wearing gloves

Features:
- 300 - 1500 Lumens
- 19600 Candela

Streamlight TLR 7A Flex - Best Compact
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.
