This is likely going to be the consensus for a lot of folks on the 5th gen G19. Again this is the issues I had with the 2nd gen guns and will be an issue with the 5th gen. Some may not see this as a big deal, but after a bit of shooting, the cutout really starts to irritate my pinky. The cut out isn't an issue on the full sized guns, so I might get a 5th gen G17 to replace my old 2nd Gen 17 range gun, but the 5th Gen G19 is out for me.
