I just haven't warmed up to the grips of the gen 4 yet, aas far as looks or feel. I have not had a problem out of my gen 3 so I don't feel the need for the gen 4. I shoot my FIL's gen 1 and gen 2 Glocks every now and then and they feel quite different to me but shoot fine.

You give Peace a chance, we will cover you if it doesn't work out.
