Wikipedia said:The extremely rare 92SB, Initially called the 92S-1, was specifically designed for the USAF (US Air Force) trials (which it won), the model name officially adopted was the 92SB. 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.
