Streamlight tlr-8 tactical weapon light w/red laser review - Streamlight TLR-8 Tactical C4 LED Weapon Light w/Laser Sight

The Streamlight TLR-8 Tactical Weapon Light w/Red Laser Sight, 500 Lumens zero'd in 3 shots. I have shot 500+ rounds throught it banging the mags against the side and bottom between mag changes and it's still zero'd. Not surprising since it's all machined aluminum construction metal allow housing! Just like the TLR-1 HL, this is a quality product with a Laser...

TESTED: Mounted to M&P 2.0 9mm Compact 4.0". I have removed it and re-attached it and Still Zero'd!
NOTE: Tried it on M&P 2.0 9mm Compact 3.6". None of the 1913 KEYS shiped with it would allow clearance between the back of the light housing and the pistol trigger guard of the 3.6". It caused the unit to cant or aim upward slightly.

IMPORTANT: I had a Crimson Trace Rail Master prior to this "a plastic POS" During the first few mags it flew off the pistol 1913 rail. After inspection, the plastic side mount of the Crimson Trace Rail Master unit had broke off!
