Hellcat version compatible w/ hk cc9 - Streamlight TLR-7 HL-X Sub USB Multi-Fuel High-Lumen Rail-Mounted Light

I have several iterations of the TLR7 lights. The third light i purchased is tlr7 sub SA/Hellcat HLX light because it is compatible with the HK CC9. It fits really snug in the back. If you think it doesn't fit, push harder. I really like these lights' output for their size. Last year, I traded my first tlr7 light ( sub SA) to the TLR 7 HLX on my hellcat pro.
