People seem to like to debate terminal ballistics so this provides that opportunity. The 40 versus 9th thing is getting old.
I think the biggest appeal as mentioned up thread is adequate terminal performance with two more rounds. Because Lord knows that if you have no skill throwing more lead will fix that.
There is no magic...... Or free lunch.... in order to get of this type of terminal performance The platforms are going to be just as big and just as heavy as any other service pistol.
