Only a crazy person would buy ANY handgun and expect to stick it in the holster on day one and carry it and it be ready to roll.
Tex....
Back some years ago we did exactly that. Even match-garde bullseye guns made by the likes of John Giles, Jimmy Clark, Austin Behlert and Bob Chow that shot sub-three inch machine rest groups at 50 yards (and came with a test target to prove it) could be taken to the range on day-one, be loaded without any special effort, and they'd start ticking from git-go.
At this time, Colt was the only maker of commercial Government Model .45 pistols, and it was very seldom that one wouldn't perform like gangbusters out-of-the-box. They had numerous inspectors' marks, and if a bunch came back to the factory they'd be traced back to somebody, who would either straighten out and fly right of get fired.
No one hesitated to take a new S&W or Colt revolver, load it, and go forth.
This "you got to expect to shoot hundreds or even thousands of rounds through a gun before you can expect it to work" is a relatively recent development - and I'll admit that's the way they make things today. Both Tuner and Jim Keenan are old enough to know exactly what I'm talking about.
I can see both sides in this incident, but Les could save himself some trouble if each pistol that was shipped contained specific instructions about why and how this breaking in process was supposed to be done. Then at least, everyone would know what to expect.
But don't think for a moment that a 1911 pistol has to be broken in. Obviously Uncle Sam's military wouldn't have stayed with the pistol as long as they did if that was the case.
