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.
