A Beretta Centurion is the equivalent of a 1911 Commander size gun. In the 1911 world, a Commander has a full size grip and a 4.25" barrel vs the Government Model's 5" barrel. In the Beretta 92 world, the Centurion has a full size grip and a 4.25" barrel vs the M9/92FS 4.9" barrel.
Since they weren't making a military gun (5" Government Model, M9/92FS 4.9" barrel) when they introduced the PX4, they skipped the longer barrel and went direct to the Commander/Centurion size, a full size grip with a 4" barrel.
