My hostility against Silenced ZMG stems from the fact I knew it would cause more trouble.  Specifically, the secondary function toggle.  PP7 and PP7 Silenced have a large difference in accuracy...PP7-S was used in all the multiplayer loadouts except for Mines, which also featured ZMG (which is better than KF7 ignoring the scope) and AR33, which is a +40% damage and highly accurate rifle.  The PP7 is unsilenced to make it competitive with the strong weapons of that loadout.
A togglable PP7 means you get a blazingly accurate pistol in models that shouldn't have it.  Look at Pistols.  PP7S, DD44, and CMag.  The whole idea was PP7S was a bit more accurate than DD44, but shorts you a bullet.  CMag is hyper accurate and penetrates, but is dog slow.  Allowing PP7U gives you almost-CMag-accuracy with semi-auto fire rate.  DD44 becomes a Klobb in comparison.
All because that stinking weapon icon font that isn't even used anymore had an erroneous silencer.
