Tlr-3 nice compact light - Streamlight TLR-3 Compact Rail Mounted Tactical Light

bought it for my Glock 17, fits the gun nicely, comes with different attachment accessories so you can mount it on different guns. Pretty good light, bright enough for most situations, I just wish the price was little bit less. But anything that you mount on the gun is always ridiculously overpriced.
Pros: Small, lightweight, bright enough
Cons: none so far
