Hi I am new to this I bought my second gun and it is a Bersa Bp9cc I love the gun..I went to the range probably the 3rd time with the gun and when i pulled the trigger 2 bullets were shot...I thought it was just me and blew it off it happen to me a second time 2 bullets went off on one pull of the trigger..I do not want this to happen when my wife has it and it decides to unload the whole Magazine and she turns will the gun like whats going on...Any one have any idea what is happening?? Thanks
