It was also standard issue for air cops (Security Police) until about 1994, used a 130 grain FMJ load.S&W 15-3 in one of the most outstanding revolvers you can have -- DON'T EVER LET GO OF YOURS! My son, retired from SAC, said that was the pistol issued to B-52 crews in cold war times. It is the most accurate revolver I have.
