I have the greatest respect for Old Fuff, but I think it is very unlikely that a Colt VP or a Baby Browning (not the 1906, which is the same as the Colt) will fire a live round while it is being ejected. It would take an extremely sensitive primer or some malfunction before the slide could be brought back with enough force to fire the round. I will grant it is not impossible if the extractor and slide trap the round and prevent normal ejection and if the user is able to slam the slide back with a lot more than normal force and if the primer is sensitive, maybe. But not something to worry about as far as I am concerned.
FWIW, the Browning M1910 and 1922 use the same system, as do other small pistols and I have not seen concerns voiced about those guns. I think it a lot more likely that a user would fired the gun by pulling the trigger while trying to eject a round. Some pictures of any such incident would be useful; the round being fired by the firing pin while ejecting should pretty well destroy the pistol.
Coltdriver, I am not sure what gun you are thinking of, but there is no little pin in the striker of the Baby Browning, and the safety does not block the trigger; it blocks the sear at the rear, not the trigger at the front. The safety has no contact with the trigger. True, there is 1/16" sear engagement preventing the gun from firing, but that is over twice as much as in the hammer of a 1911 pistol and most folks suggest they can be carried safely cocked and locked.
EBK, that little MAB is often called a "copy" of the Colt Vest Pocket, but that is a generality; they are different pistols and parts do not interchange. Some parts might be adapted to fit, but that could not be assured.
