The G.50 was a crap in real life, and it's a crap in the sim as well.
The thing though, is that it looks like the plane is missing about 200+HP (there was a discussion about this some times ago), so its performance is really sub-par.
Now... why did the Regia Aeronautica choose to adopt such an ungainly, modest and even dangerous fighter plane can't be explained.
Especially since the real winner of the Fighter plane tender of 1936 was the superior and actually very good Macchi C.200.
Fiat was a huge competitor and represented a huge industrial actor,so just think of the most obscure behind-the-scenes actions(bribes), and just do the math

p.s. Maybe I was too crude, but boy, do I hate Fiat...
