After shooting a friends G19 with ZEV kit, I purchased a G17C GEN4. I polished all the trigger components, installed a set of Wolff competition springs and a Ghost rocket connector. Trigger feels real smooth with positive reset. This thing is sweet. Sights were right on. I went through 100 rounds in just a few minutes. I really enjoyed shooting the Glock today. I think I became a Glock fan today. Going to retire my Kimbers.
