I just cleaned my Ruger MkII for the first time this afternoon. It only took me three or four days to get the mainspring back in. About the Speed Strip Kit for Ruger Pistols: It looks good. What’s not clear to me is from the video is; Does one still have to remove the mainspring to remove the barrel from the lower? Is a mallet still needed for that? Can the trigger weight stay the same as stock? Majestic Arms says it can be done by anybody with ordinary hand tools. How are the threads cut in the barrel? Is a tapping the threads that easy to do?
