In Navy boot camp in 1970 we had these.
The bolts were welded shut and we only carried them when we screwed up or when we were trying to march in formation.
Definition of a Navy formation was more than one boot going in about the same direction at approximately the same time.
We spent a total of around 6 hours at the Marine range actually shooting live ammo with Marine DIs yelling at us.
Out of 62 guys I think 2 or 3 actually qualified.
None of us qualified with the 1911. Mostly because there were no targets to shoot at. The DI held your arm and yelled at you to pull the trigger until the pistol clicked.
Then the DIs were kind enough to let us reload mags for the rest of the day.
Sweet, a 1903 Springfield. I have one of those!
