First time post. I recently picked up a FPC and it has the fin grip, I’m Illinois and not in California. I was told that the back strap can be removed and I can put any 2.0 backstrap on in its place. The problem I’m having is the frame tool does not turn at all. Am I stuck having to dremel the fin off? The fin is not required in Illinois, so I’m not breaking any laws by removing it.
