I purchased the Streamlight TLR-2 laser light combo about a month ago and couldnt be more happy with it. It has a very bright laser and the light is blinding( I found out first hand before i put it on). But the thing I like most is after I attached it to my M&P 40 I felt it gave the light gun excellent balance and even found myself hitting my shots a little better with the weapon. About 500 rds through and the TLR-2 hasn't even budged. Has anyone else noticed better balance with the additional front weight of a light or combo added to a polymer pistol advantageous?
