it seems to me that those coming from a G36 to the G30S have no issues with the recoil and those coming from the G30/G30SF/G30 Gen4 think the G30S might be a bit snappier than a G30/G30SF/G30 Gen4...
I would have liked to try the G30S and a G30 Gen4 back to back but couldn't locate a G30S before I made my purchase of the G30 Gen4...
I'm very happy with my purchase but will always wonder...but then that's always a reason to buy yet another gun...
