I've read several posts regarding this issue, but nobody seems to have a answer, other than, "send it back to Ruger". Frankly I'm going to take it back where I bought it, and sell it for a loss. My SR40 shoots awful, and jams non-stop. My wife's SR9 is just fine, but the .40 blows. It jams every time I pull the slide back. It's not a gun you want to have in an emergency. Hell, it's not a gun I want to have at the range. And it turns out, lots of people have this same problem. I'm Done!
