I think that a Hornady Critical Defense .45 ACP 185 Grain would probably take care of that more reasonably ?
My same thoughts, I would have taken out the tires on the Benz, and even the Hellcat if it cam to that.
Two things you never hear: "I had a Ravelco installed, and my Hellcat got stolen" "I had IGLA installed, and my Hellcat got stolen."
Yes I have one, it kills the accelerator pedal, locks all 4 wheels with ABS, blares the horn, has a light show, also has hijack mode. I could leave my car open and the fob on the seat with confidence that my car is going no where.
