First I just want to mention, I have yet to find a grip that holds a battery that doesn't have problems. Some are very weak and will break because the walls of the grip is thin to make room for the battery. Others I messed with didn't fit a rail properly, like what your experiencing.
If it wobbles on the rail, you can do a couple of things to get it tight again. If the wobble isn't too bad, you can put a layer (or few layers) of electrical tape on the flat surface that contacts the rails. This method is simple but if you remove the grip often, it will need redone from time to time. If you want to fix it up more permanently, you can add a layer of JB weld to the same area and let it cure completely, and then sand slightly and fit it (repeat as needed) to get it exactly how you want it. These tricks helped out with many different ill fitting accessories I encountered.
