1. Preheat your grill to 400 degrees Fahrenheit.
2. In a medium saucepan, melt the butter. Then add in the garlic, lemon juice, Old Bay Seasoning, parsley, tarragon, thyme, lemon zest, and cayenne spicy sauce, whisking constantly. Half of the garlic butter should be divided among four dipping cups. Half of the mixture should be left in the pan.
3. Cut a slit down the inside of each crab leg with meat shears to allow the butter to enter through the shell and into the flesh. Brush the garlic butter mixture on the crab legs in the saucepan.
4. Place the crab legs on the grill grates that are still hot. Cook for 6 to 8 minutes per side, or until the flesh is firm and looks pearly or opaque.
5. Remove the crab legs from the grill when they are thoroughly cooked.
6. Serve and enjoy with a garlic butter dipping sauce.
