Rainbow Six: Vegas. Guns have selective fire. If Ubisoft can do it, IW can do it. they chose not to for balance reasons probably. Same reason the Barrett does the same damage as the Intervention. It's for balance reasons.

It's also obvious that a weapon would still kill in one bullet, even if fired from a suppressed weapon. They toned it down in order to make Non-HC matches more fun.
