can someone tell me or post a pic of a full sized glock with the new m6x laser aiming light on it. i wonder if they are the same size or not. debating on the original or x model. thanks!

No one has an M6X yet.  The M6X is vastly superior to the M6.  FWIW, I'm waiting.

It would have to be very superior to warrant double the price for it. What makes it so special if no one has seen one?? I have a m6 and it works very well.

I have an M6X.  It's  white light is brighter than the standard M3 I own.  It also has a end cap to plug a pressure switch into, but mine is an older prototype I was sent at work to try out.  I don't know what's gonna be on the production model.  It appears a little more robust, but I never had a problem with the normal series light.  I guess if you want a brighter flashlight it might be worth the money...
