I picked up a NCSTAR weapon light. It was $20.
Worth it?
Return immediately if purchased at a retail location. Eat the restocking fee if it's reasonable like 10%. Take the money you get back and put it towards a Streamlight TRL-1 or a SureFire X300. Save up if you don't have the money. No it's not worth it. I don't have first-hand experience with the light but the NCSTAR brand says it all. Even if I got it for free I wouldn't use it on my pistol, because I may need to grab that pistol in the dark to defend my life, family, and friends. I do not value their lives and my life to a $20 toy hobby light. Anyone competent with firearms will agree with me. Guns are serious tools, and they require serious accessories if it is your wish to truly enhance the tool's capabilities.
