Ordered trigger spring kit for TC Venture. The spring kit worked great , it reduced the pull from 3lb7oz to 1lb10oz. The videos are the best, second to none.👍 As for service that's another story. I called at least 10 times never a response. Apparently they don't answer there phones just a recording. Also emailed at least that many times or more with only 2-3 responses. That being said I will probably order agin in the future. As I said there product are good and videos are great and very easy to follow. I just hope they work on there customer service a little or (alot) !!!!!
