The RMB has a tiny bit of play compared to the firm left button, and I can 'replicate' this on both of my G502's. However it only does that right click with an -unrealistic- amount of force/dropping that you would never do under real playing conditions. I never made it happen under COD Black Ops 2 or league of legends, so this is a complete non issue..
My deathadders and even my old intellimouse explorer 3.0 would not click if you simply free-dropped the mouse, but if you were HOLDING the mouse and dropped it like that, your finger would press LMB or RMB, as they were so easy to depress. Which is basically the exact same thing (and I remember doing that accidentally nonstop in UT2004, until I 'stiffened' up the RMB, and that was a BIGGER issue than this unrealistic 'drop the mouse and right click' test).
I was never able to accidentally cause RMB to depress except by intentionally using unrealistic LOD/dropping to make it happen. I can't make it happen with a normal LOD and putting it back down with 'more' than the normal drop rate (e.g. using my wrist to make it drop ***ster). Now if I SLAM it, yes it happens, but why would anyone slam the mouse?
BTW, its the 'vibration' of the right mouse button that's causing it to press when you slam it down like that.
Plus that is just going to either wear the pad down faster, or wear out your feet faster.
This mouse has a 1.2mm lift off distance..why would you lift it 2 inches off the pad and then slam it down?
