Over the years, I've been kinda on the fence about rail mounted flashlights on pistols. Don't get me wrong, they are extremely handy. Anytime you can mount a light on your weapon, it's a plus. I have a Streamlight TLR-1 on my Mossberg 500. But for some reason, I just never planned on putting a rail light on any of my pistols. I always just used a hand held flashlight. I always thought by having a light on your pistol, you were breaking one of the four rules of firearm safety: never point your weapon at anything you are not prepared to kill or destroy. Pointing your pistol with the light on it at your spouse or kid when they get up for a midnight snack and wake you up falls under this category. So, I'm watching some youtube vids yesterday when this one catches my eye... I think another reason I never wanted a light on my pistol is because they look so big and bulky to me. I always thought maybe if somebody made a light that was compact enough to not stretch past the muzzle and not be fatter than the slide or frame, it would be easier to carry comfortably. The TLR-7 does this. Plus, with it's 500 lumen output, you can get enough spill to illuminate a room without getting little Johnny or Suzi in your sights. So about a week or so, I had planned on buying the Inforce APLc. It looked like a good light. Not bad as far as lumens goes (200) but it was powered by a stupid CR2 battery. I'm already feeding about a half dozen or more lights that use one or two CR123 batteries, I did not wanna hafta buy another type of battery. More good news - The Streamlight TLR-7 uses a single CR123 battery! According to the below video, they are supposed to be available after SHOT and will run in the $125-$150 range. They also make a TLR-8 that has a lazer on it...if you're into that sorta thing.
