M&P 22 Compact Threaded Barrel Question?

I just made an hour and a half drive to pick up the gun only to realize it has a threaded barrel which I don't want and I'm not even sure it is legal in MA. I called S&W and they won't sell me and have no plans to make barrels available for the 22 compact. I just don't like the way it looks hanging out the end of the gun. I was wondering if anyone had any thoughts on ths? Can I send the barrel somewhere and get it cut?

Thanks,

Phil
