When I was on active duty during Operation: Desert Shield & later Desert Storm, I saw a
Stars & Stripes photo of a combat fighter pilot(unknown if he was Navy or USMC) on the flight deck of a aircraft carrier near Iraq.
The pilot wore a full flight suit with SERE(escape & evasion)vest & slung low on his hip in a leather holster was a big Colt 6" barrel .357magnum revolver,
.
I doubt the 6 shooter was milspec but he looked ready to handle any bad guys if he was shot down in SW Asia.
