Anyone have a pic of a 21SF or 21 with a light mounted to it? I have been reading on here and I think I want one for my HD G21SF but I want one that is not too large. Any pics or input? I am leaning towards the X300 or 400 but wanted to get an idea of how far it sticks out on the full size guns. And I did search but there are not a lot of pics oddly enough.
