I'm considering purchasing a weapon light to go on the rail of my G22 that I can slide on the gun when it goes into the safe for the night. Of the three listed below, I'm looking for opinions on which one is the brightest, most durable and best value. Glock Tactical Light Available for $95 from TeamGlock.com and $89.95 from Lone Wolf. I haven't found anything that tells much about this light as far as brightness is concerned. Surefire X200B An LED light available from Surefire for $275. I thought they used to have a non-LED weapon light but there isn't one shown. Having owned Surefire lights (a 6P and a G2 Nitrolon) I know they are good lights, but are they worth $275?? Streamlight M3 Available from Lone Wolf for $119.95. I don't know much about Streamlight, but the M3 seems to offer a few features that the Glock light doesn't for an additional $30. I have a friend who is an Austin police officer who carries the M3 on his G21 and he really likes it. Based on price alone, I'm pretty much ruling the Surefire out. Any thoughts on the Glock light or Streamlight?
