As much as I don't like to tell you this, you should call Bersa (Eagle Imports) and follow their recommendation. If it was purchased new, It should have been sent back to them. Have him go onto you tube and type in Bersa Clip fix or similar key words. Lots of good videos and how too's Good luck.My husband purchased a Bersa .40 Thunder Ultra C back in February of this year. He only shot three maybe four mags thru it when it started jamming. It jams with both mags that he has. He took it back to the gun shop where he purchased it. They sent it away to MN to an armorer. It took about three weeks. It came back "fixed". He shot it this past Sunday and again it jammed. It's not how he's holding it. It jams for other shooters too. It jams both indoors and outdoors. The gun shop swears its the very first Bersa that they have ever had come in for repair let alone a brand new Bersa having issues. Anyone have any advice? Ideas? Different armorer? Thanks!
