sorry ruger redhawk, gotta disagree with you 100%, I have 4 m77's and all have had timney triggers installed and set at 2.75#'s. I had my smith do them and he said that the timneys are super easy to install and adjust, and do not require the stoning that the stock ruger trigger does. One problem, if you need to send your gun back to ruger for warranty work, put the old trigger back in, they will rip out the timney, put a stock one back in and probably charge you. As for cost of a new timney ....$116 installed (price included tax) Just my opinion, but replace it!!!
