Personally I would just run the brimstone trigger if you want an overtravel stop. So much cleaner install, hammers and sears seem to vary, some are happy with the ones they used others not so much. My Power Custom set was great in a 10/22 but has a small amount of creep when installed in the PC and I would definetly not recommend using the 10/22 hammer spring. The weight differnce in the pull is tiny and the PC spring gives a more positive reset without the chance of it doubling on you or the hammer getting bounced off the sear and not resetting. Right now I have about 3k through mine and its starting to have ejection issues. Gonna order a new extractor from ruger if they have them and see how bad the tip is worn on mine. Right now its losing control of the case when the ejector hits and instead of pivoting out of the gun its hitting the forward section of the reciever. Sucks because this thing was dead reliable for 2k plus rounds.
