Good question, I look forward to talking to Ruger tomorrow about it. Like I said I bought 2 - .49 cent 9/64 inch Allen wrenches yesterday and will keep an eye on it when I get it back and see if it will be a problem, if it is well I will call Ruger. But I shot 300 rounds through mine and the barrel stayed tight. I really look forward to see how myself, you and I can't remember who else sent theirs on here back to Ruger works out. Dave's is doing well I think, what ever is going on I hope it works out for all of us. Anyway we seem to me the pioneers for the SR22P for this forum. All we can do now is hurry up and wait. computerdynamics if you call Ruger about your please let us know as I will post what I find out.
