I just received my Evolution trigger back from install by SharpShooter Supply. As recieved it breaks clean & crisp at 3 oz. According to SSS it will adjust even lighter. I'm going to shoot it like this until I at least get used to the 3 oz. trigger. I had excellent service from SSS. I shipped my rifle on 8/18/14 and received it back 9/9/14. I've seen some posts in the past blasting them but as far as I'm concerned I could only highly recommend them as long as your work is pre-scheduled with Lisa at SSS I think you will be a happy camper. ;D
