Not interested in g19 gen5, but would like to handle g17, kinda doubt it will feel any better then my gen 4 g17
It will feel very similar except for the finger grooves being absent and you may or not notice the cutout on the front of the grip to access the mag if it becomes stuck. However, this seems to be more of an issue with the G19 than the G17. When i picked up the gen 5, G17, I thought it was just like my my Gen 4 without finger grips.
