I was shooting in the FL IDPA championship this weekend on a stage that was completely blacked out. The only light available to me was a flashlight, which by IDPA rules could not be mounted on the gun. I got my hits (-5 over 8 targets) but was way too slow, just too much fumbling with the light. But I do have some observations about that exercise as it relates to choosing/using night sights, laser grips, etc.
Without a light, night sights or laser grips really are not doing anything for you. The scenario I was in was completely blacked out- no ambient light at all. As I approached the targets (shooting through portals and pieing corners), I would light them up and my sights were available. I tried that without a light but had grips or night sights, I would have been literally shooting in the dark with no real clue where my targets where until muzzle flash lit them up.
I also remember shooting in similar conditions with my S&W 649 with CT laser grips. I noticed that on a poorly lit (95% blacked out) target the laser was not very useful to me; again with a light the laser would have been much more helpful.
The only option I can think of that would help more than what I mentioned above, but still would need a light, is a slide mounted red dot. And I would be remiss if I did not mention, that I don't practice enough (like not at all) with a light and that I should practice with one.
Don't get me wrong, I'm not peeing on your favorite night sights or laser grips but I think it's important to understand they have some functional limitations one should be aware of.....
A couple of notes:
I was shooting a Glock 19 with FO front sight and plain Warren rear sight.
I had a Surefire flashlight
