Have the same gun and have never experienced what you have. Not knowing your experience, make sure that you are gripping it firmly. Not gripping it correctly may cause your issues. Also, like it has been mentioned, do a detail cleaning and do check the extractor for chipping. Looking at the ejector from the front of the frame, the tip of it should be tilted to the left. As for ammo, I stay away from WWB and use Federal, Fiocchi, S&B new brass FMJ for target and Federal HST for SD.
