Shocking terrible fit - SureFire X300 TURBO Series-A High-Candela 650 Lumens LED Weapon Light

Went to mount this light to a G19 gen4 and it was absolutely shocking how bad it fit. Wobbly, loose, like a practical joke gone wrong. I had to replace the quick-detach mount with the other supplied rail mounting option in the box. It was still loose with their “universal” locking bar so I had to take the picatinny locking bar and shave it down bit by bit to have it attach securely to the pistol, as well as ad layers of gorilla tape to the back of the body to keep it tight. Two stars because the actual light it throws IS impressive, but for a $300+ light marketed as a premium product, I’m pretty pissed at how bad it fits on basically the most likely firearm it would ever be mounted to. Honestly don’t see myself buying another surefire product in the future.
