Most threads I remember contained threads from people that owned, and liked the Rhino. Most say they noticed an appreciable reduction in muzzle flip, and felt recoil. I've posted comments myself mostly similar to my first one in this thread commenting on the looks, and complicated workings of the Rhino. I think I once said it looks like what a Hi-Point revolver would look like if they made one.
If you don't mind the appearance, and can get a good price, It would probably be a decent purchase for you.
