This is a drop in 3 1/2 lb connector. Ghost trigger connector. I don't like.(I matched the angle) The stock one has a slight travel, stops, then breaks. Weird. I used the same one in the Glock 23 Gen 4 and love it..Must be something with the G30 sf with the stiffer firing pin spring. I ordered another Glock model 3 1/2 trigger connector..when it comes in, I will update.
