I run the S3G trigger too and with a little tweaking it's very nice, probably the best I've used to date. I've tried triggers from JP, McCormick, pact, Jewell, timney and A couple others and the new S3G is as good or better than all of them. And super easy to install with a great feel without adjustment.
I have a pact AR gold that feels really nice but the pre travel is terrible. As soon as I can get the S3G trigger pull to around 1.5 pounds I'll be very happy
