Yeah I had to order my Gen3 but said it would only take a couple days. Probably will be here tomorrow I am guessing. To be honest, I shot the Gen4 once and didn't notice too much of a difference besides the annoying texture on the grip. Recoil felt about the same to me. I have seen some gripes about the ejector and seen some highspeed video of the casing being tossed around inside the gun before being ejected out occasionally causing it to get stuck. I figured I would rather pay less money on an older model that I have shot before and know has a good track record.
