C-Bug.

[Maddolis]

I really do disagree.
I'll fight you, my weapons being (in different rounds) uzi, tec9 and grenades and yours deagle.
I'm pretty darn confident I'd win the uzi and tec9 rounds, where you should win the grenade round.

And I stand by what I said about "It is probably just as powerful as most popular weapons anyway," being untrue.

The popular weapons (aside from the deagle) = Sawnoff, uzi, tec9, and perhaps m4.
The deagle has a disadvantage against the sawnoff uzi and tec9, and at a distance, the m4.

A combat shotgun fires many bullets within a few seconds, just as fast as the C bug, so why can't you? You could even post a suggestion to add it as a spawn weapon in 2.90, I'll do it personally if you like.
Edit: After checking the source, remembered that a combat shotgun already is available as a spawn weapon, just not a regular shotgun.

I realise its in the game, and have used it before, but the user is still more vulnerable when unable to use the c-bug.
As most walk-weapon fanatics would probably agree, the c-bug is not so much about firing faster, but about moving faster. From skipping the post-shot animation, it allows you to move around and dodge an incoming shot better than waiting in the same spot for half a second without firing.
More defence than offence imo.
