So I love all my glocks, and can shoot them well stock. I was in BWGs and one of the guys there was showing me his G27 that he installed a ghost 3.5 trigger set up on. He let me dry fire it and I gotta say it felt nice. I'm trying to get some opinions on it first before I shell out the money for it. Is it worth it ? The Glock models I have are 21sf, 30sf, and 23. All gen 3s. Anybody have any of those with the Ghost job? And how do you like it.
