I have a G17 it's my only firearm(for now) so it serves as both home protection and range gun. I'd like to put a light on it not really interested in a laser combo just a led light, something that I can leave on while at the range to make sure I am comfortable shooting with it in case I ever need to use it for self defense(god forbid). This is my first handgun so I don't have a lot of experience in this department and would love to hear what you guys are using or what you have found to be the best tactical light in your experience. I was told that the factory Glock lights weren't all that great which was hard to believe with the amazing track record of there firearms, is this any true? Thanks in advance guys!!
