I have a Gen 4 G19 that I’ve carried for ~ 4 years and just recently bought a Gen 5 G19. I also have a Gen 4 G23. Not familiar with the “C” designated line. I know that I prefer to carry my Gen 4 G23 with 357GIG conversion only because I’m more accurate with the 357 caliber.
Sorry, cannot speak to the “muzzle flip” as I don’t notice it to be an issue with eith my G19 or my G23 (don’t pay much attention to or factor in consideration to flip and recoil.)
