Great solid light for the price! - Smith & Wesson Delta Force RM-10 LED Weapon Flashlight 500 Lumens

This is a Nice light and extremely reasonably it comes with a pressure switch and button end cap. most pressure switches come with double sided tape so its stuck where you put it, this one has nice velcro straps so you can put it on and take it off and put it on a different gun and so forth. 500 Lumens is plenty bright for what most civilians are doing, it comes in a small package, and can take some abuse. So if you are on a budget and need a light this is the best on you will find.
