Power in spades

When going after kingfish or other big fish and you want big grunt with accuracy, this is a great gun! It shoots straight even though it’s got big recoil-kicks back when you shoot. If you don’t mind the recoil, you can be confident in this hard hitting gun when going after big fish.
