Rossi 22 Magnum

Has anyone had a go with the Rossi 8122m 22WMR? I have been handed one and wonder what you get for the $400 they sell for?
It has quite a short and narrow stock and LOP, fits me well and the young fella can wrap himself around it too. It is very light to carry.
Brand new out of the box and rounds wouldn't feed from either of the two 5 shot mags. A quick tweak on the feed lips and that was sorted. But a bit disappointing for a new set up. The trigger is very firm, hoping that frees up with use.
But the important bit is do they shoot? Has anyone got any feedback? Or come up with any mods to improve it?
Is it worth hanging onto as anything more than a plinker?
