Look for signs by checking the round in the chamber and by looking at expended brass. Look for the photos of the unsupported chambers and look for photos of the Glock pimple. Good information to have.
But the tipoff that looking is even required is right there in the manual. There was, at one time, a problem sufficient to justify adding the warning to the manual. Just something to show that some amount of investigation is warranted.
Were it not for the published warnings, this thread wouldn't even exist.
I have heard that Federal brass was a little wimpy in the early days but I have seen the photos of the unsupported cases and the Glock dimple.
