This gun my brother originally bought as his duty weapon in middle 09. He kept having problems with it failing to go into battery so he switched to glock after the academy. He sent it back to S&W and they sent it back saying it was fixed. He has shot several types of ammo and tried brand new magazines and still the same problem. He has shot it once since getting it back and we shot it again today. This is what we got six times in 3 magazines. Any insight is welcome.
