The battery is not removable, so if you own other Streamlights and are planning to keep charging one battery and changing them out, this won't fit that regime. However the battery lasted nearly ten times as long before needing charged, compared to my other ones that the battery comes out of. (the green battery).

Fits a Gen 4 Glock 22 perfectly. Pretty damn easy to assemble and even easier to use. Bright as hell too working nights as a deputy.

A little disappointed tbh - it didn't say the wavelength where I bought it. I've heard higher wavelength like 930nm is not noticeable to the human eye, for the price they should have used that. If you buy this thinking it will let you get the drop on a bad guy in the dark with nightvision, be aware this will likely give you away. Also the IR illuminator is a little too bright for the laser dot. Calmly walking around my house in the dark I can usually see and follow the dot, but it is only very slightly brighter than the illuminator, and I noticed loosing the dot with certain objects (shine/eflectiveness?) or objects that are very close (illuminator gets much brighter and washes out object detail/laser dot). That could be the fault of the sensitivity of NV device I was using however, I don't know (syonix). I have only used this for a few minutes so I can't comment on durability or battery life.

great product fast shipping.

didn’t come with bolts or nuts
