You do know your Taurus (everyone thinks its a junk gun) owns Baretta
They are built to the same standard.
Seeing as your man can clear the clip and not have any problems I would feel safe to say it is you.
Have you paid attention to what you are doing? Maybe a little limp wrist after a couple rounds?
I am also not a big .45acp fan but that is more of a shot placement arguement and probably not needed here.
Do you have any problems with other auto hand guns?
