Picking up a new Hellcat tomorrow and looking at lights. I read that the Streamlight TLR-7-Sub works but I need to pick a rail type to order. The choices are 1913 rail, Glock 43x/48w rails and Sig 365. All I see is that the Hellcat has a standard accessory rail. Anyone ordered this light that can tell me what type of rail they chose for the order? Or other light reccomendations? I know the Surefire XSC works but I am not liking the price. Thanks
