Mine started doing it. I returned the gun to SW and waited 4 weeks. They returned it (replacing the barrel) but it does the same thing. I then called SW they had me send them my mags.

They also said that for my trouble they would send me a mag while they repaired mine.

Yesterday I got a call from SW they cant send me my mags to someone without an FFL (They said Mass Law) I am having them sent to a gunshop.

Funny they can send me back my gun but not magazines


Then I got a call from the service rep who promised my a free mag. He cant send me the mag again because of mass law.
