Old Corps used to call it cocked and locked; that was b4 lock and load came into vogue...

Semper Old!

One day around June 1967, he turned a corner in the path in some very heavy green stuff and ran face to face with an NVA command group of five and he had his pistol in his hand. He got hit once on the inside of his thigh but he killed all five of them.
Lock and load is backwards. One opens the breech on a cannon, loads it, then locks the breech. I don’t know how that got turned around in common parlance. Many semi autos come with adequate safeties to carry with a round in the chamber. But I wouldn’t want to stuff a Glock in my pants that way. Better to have in a good holster.
In my time in the Corps it was “Locked and Loaded”.
That was in the M1 Garand era.
And before anyone ever heard of Ooh-Rah we had Gung-Ho.
And Gyrene was still in common use.
