Every weapon used for self-defense needs a light on it. Period. Regardless if it is a handgun, rifle or shotty.
Before these nifty shotgun forend gadgets came along back in the day I used a basic picatinny mount for a Streamlight TL-3 Flashlight and a curly cord pressure switch!
It worked great and I ran it for years and years with no problems.
Bottom line guys is the the Nightstick SFL combined with the Streamlight TL-Racker are the two best budget friendly options for shotty forends, priced out at between $100-150 for the LIGHT only model.
Not sure why you would need a laser on a Shotgun? But if you want to pay the extra money for it, go right ahead.
The Streamlight TL-Racker is rated at 1,000 Lumens while the Nightstick SFL is rated at 1,200.
I think the determing factor between these two will be DURABILITY and how well they handle the punishment of multiple rounds of 00 Buckshot.
Stay Tuned for a Field Test Comparison.
