The Beretta Model 92 is a semi-automatic pistol chambered in 9mm.
The 92 has been the standard issued pistol of the US military since 1984, so needless to say it is dependable.
It has an open slide design, so the barrel shows through. It has an external hammer that can be cocked back to change the trigger pull from a double-action (long pull) to a single-action (short pull).
An ambidextrous safety also acts as a de-cocking lever and when pushed down it rotates the firing pin out of alignment.
A second safety feature is its visible automatic firing pin block, which prevents the pistol from discharging if accidentally dropped. And, it has thee-dot fixed sights.
Beretta recommends the 92 for military, law enforcement and personal defense.
