Yeah, this mould isn't working as well on Sideswipe as it did on Jazz (and Jazz was only ever mediocre at best). The gun doesn't do much for me. The gimmick is just... nothing. I'd rather they'd dispense with it and do something better. The gun is also so big that it looks absurd when attached to the vehicle. I'd much rather a smaller and simpler weapon like Jazz's pistol; it works. Sideswipe's gun is just big and gimmicky for its own sake. It's not nearly as terrible as Kickback's gun, but it doesn't appeal to me as being particularly good either.

As UltraMarginal said, it's not terrible, but it's not good either. Only recommended if you're a FoC or Sideswipe completist, and even then try to get it under RRP.
