I agree completely . I could not understand why all my Glocks(only Glocks) would shoot left. After much research and not really finding an answer . I placed my new 48 , which was the worst of the 3 Glocks (43,22 & 48) in regards to shooting left. Once in vice and solid no movement. I filmed the sights when I pulled the trigger straight back with a tool, not a finger. Then I pulled trigger with left hand finger & right hand finger. All 3 times the trigger made the gun move left right before it released the striker. That is why the Glocks shoot left. Replaced the triggers, no problems since.New to Glocks and find the STOCK trigger to be total junk. I could watch the sight pull right as the pull increased on every shot. And push back left as it broke from trying to hold it on target. I bought a Ghost Pro 3.3 kit, installed it and what a difference it makes. Not only did it reduce the weight of pull eliminating the drifting right problem the break is now a complete surprise with the added bonus of no over travel.
It's still a long pull but I can live with that. And it's probably a bit safer than if it was a short, light pull.
Has anyone else had experience with Ghost or other kits?
