i was kinda looking for mechanical and technical info, i wasn't actually looking for opinions on the use of weapon mounted lights. i have had that conversation more times than i can remember. and for the record, you don't have to point a gun at someone to light them for identification. these lights are so powerful, you can point the light at the floor (low ready),and it will light up the entire room well enough to identify. i have an M3 for my glock, i am wanting to know if the nitrolon is as good, better, brighter, etc. if they pan out, i want one for my beretta and my 1911. thanks.
