Seriously though the .40 is a very "snappy" round. It has a harsher recoil than the 9mm. That said, the Gen 4 G27 I used to own was very pleasant to shoot. I had a G22, G23 and a G27 and I could shoot the G27 the best. I think it was the dual recoil spring that made it easier to shoot.
I'm actually contemplating getting another G27 since I sold the other one and regret it.
