The Beretta 92SB is a rare semi-automatic pistol that was made to be the sidearm for the US Air Force. It is essentially the Beretta 92FS with a round trigger guard, with some minor differences. The 92SB was the updated 92S pistol (it was originally named the 92S-1). It included the changes of the 92S, added a firing pin block (thus the addition of the "B" to the name), and relocated the magazine release catch from the bottom of the grip to the lower bottom of the trigger guard. 4-7/8 barrel, 15+1, Blued.
