I am one of those people who think that the "you gotta pull the trigger" method of field-stripping, is less than optimum.
As stated above, if nobody makes a mistake then all is well. But people do make mistakes. If they are trained to remove magazine and then operate the slide and check the chamber, to fully unload, then once in a while somebody does those two steps in the wrong order.
If that was a loaded magazine, then a gun which visually showed itself to be 'chamber empty' ends up loaded.
And the next step is the trigger-pull. With the accompanying loud sound. Possible with a tragic loud screaming sound.
So I don't like that design. And I praise the XDm design where the slide just comes off the frame without any need to de-cock the striker by any method.
