I sold it for a Gen 3 G27 after 7 months.
That being said, the G26/G27 did not get as many functional improvements as the other models due to them already having the dual recoil spring. That is why the model question is so important. If you are looking at anything other than a G26/G27 I would seriously consider the Gen 4 as long as the changes between generations are not uncomfortable for you as they were for me. Hope this helps being that I am rambling at 4:40 in the morning.
