Fwiw,
I am not a vendor but I have experience with them,
Your looking @ over 200 bucks.........
they are bulky, hard to find a holster to cover, and they hang down below the gun. Mine worked great and I have never heard of an issue with them at all as far as quality.
IMO, and in my collection Id keep it just as a novelty thing (becuase it matches and is GLOCK) but for real world use you would be better served with a TLR series streamlight or a surefire. The TLR's can be had for around 100 bucks or less, not sure of surefire prices but they are damn good lights I have seem a surefire work after being shot with a .22
