 The Taurus PT92 has undergone many revisions in design since it was originally produced in the early 1980s.Originally, very early models of the PT92 (made between 1982 and 1983) were near-exact copies of the original Beretta 92, featuring the non-ambidextrous safety, round trigger guard and, most notably, the magazine release in the heel of the shiny plastic grips.However, this design was soon replaced with the release button at the base of the trigger guard, the current industry's most common magazine catch location.
