i can tell you that a friend of mine is running a g19 recoil spring on a custom guide rod. it cycles fine and shoots VERY flat. straight back with ZERO flip.
but, since it has less preload, he has battery trouble causing light primer strikes. you could try adding more preload in the form of a rigid spacer, but you can only add as much as will still allow the slide to go fully back and catch the slide lock.
perhaps you could just order a g19 spring that allready had a higher than standard preload.
