I got a beauty of a S&W 9mm Tactical for my 50th Birthday. The gun comes with a rail for a light mount. I never thought of a light for mounting on this till now. I have a SF e2, Scorpion, UBH (on the way. Any of these lights made for this or are there only certain types of lights for the mounts? I always thought of using a light in a tactical stance separate from the gun body. Any info is greatly appreciated as I want to see the fit in certain holsters. I'll probably end up sending this to S&W for removal of the light rail. But who knows I might like the light mounted? I suspect the cost of a mount for a light to be high. Or at least cut into my light buying money.
