I am a lefty and i have some trouble with the safety on my M1 Super90. Can somebody tell me if it is possible to change the safey for a lefty and how to do it?

I bought a Benelli M1 Super90 NIB with ghost ring sights in April. A couple weeks later I went to the shooting range. After firing the first 6 rounds, the front sight fell of the barrel!!! I called Benelli customer service. They gave me a return authorization number and told me, to send back the barrel for repair or maybe replacement. They also told me, that it might take up to 8 weeks to solve that problem. Is this what is advertised as quality worth the price?
