Millie will be here this week end for 1911 shooting. The First thing I will show her is that limp wristing the 1911 will do Nothing or cause Anything to happen. This is easily shown by shooting any one of a dozen or so in 9mm and 45 holding only with 2 fingers. Then I turn the gun upside down and repeat. Thumb and middle finger only on the gun. NOW if you try this with short slide guns, from Commanders down to the 3 inchers, you can have a problem. The Original Design is meant to shoot any way you pull the trigger with the thumb safety[which was an add on, not on Browning's original submission] depressed and the grip safety down. John was perfectly content that any cavalry trooper could handle his gun safely with only the grip safety. The Military didn't have the same confidence, hence the thumb safety.
The entire dynamic of functioning changes when the slide is shortened. Not getting into that....
