It's made for extreme close quarter battle where you would press the musle on your ennemy and still be able to fire.
If you did that without that attachement, like said above, it would prevend the gun from firing if the slide is pushed back a little.
It also make a great striking tool with a deadly follow up.
The anti-suicide aplication... I don't think so.
