The side/sides are a real deal and if someone would take the thing apart and do some polishing they would come around. I heard of a fellow that put valve grinding compound and toothpaste in the action of one and sat for many evenings working it while watching TV and according to him it smoothed right up. Didn't see the gun after the fact so I can't say for sure.
I did the same thing on my side by side and it is really smooth now. The only problem I've had is a spring that pushes the trigger forward to switch to the other barrel after you fire. All it needs is a little stiffer spring.
