Just bought a Streamlight TLR-1 for my Glock 21SF. After years of reading pros and cons (esp in comparison to using a flashlight in the off hand) I finally took the plunge and got one for HD. I live in the woods, with lots of wildlife and other people's animals roaming free, crawling around under my house, jumping off the deck railing, etc. If I got up to investigate every sound outside, I'd never get any sleep. However, those times I have heard something loud enough from the direction of my truck and toolshed and have gone to investigate, it would have been very nice to have the weapon and light unified. That's why I got one, for all those of you that hate lights and the mall ninjas that buy 'em. Here's my question: what's the accepted technique for using these things? From what I've read in my searches on here, it seems most folks say you should illuminate only briefly, then shoot and move. Makes sense. Seems to me like the 1-2 in boxing: the jab (the light) finds the target, the straight right (the bullet) crashes through behind it, and then you move to a new angle and reset for another attack before getting tagged. So, on the TLR, do I use the trigger finger to activate the light, or do I use the index finger of my support hand (left)? I see disadvantages to either approach, the worst of which is that the "momentary on" position is downwards on the left side-- if I'm holding my finger in that area and fire, won't the muzzle flip knock my finger off the control? I haven't fired the weapon w/ the light attached yet-- probably this weekend. I just want to know what's worked for other users of the TLR and similar lights. I've been boxing and grappling and doing mma for 9 years, so I know intimately about the importance of not only having muscle memory but having also performed techniques under stress, w/high heart rate, pain, disorientation, tunnel vision, etc. If I'm gonna add a complication to my weapon, I want to master its use. Thanks to all of you for your help. Sorry for the long post. And don't let the low post-count fool you-- I've been a regular visitor to THR for years.
