Honestly, I'd hold off. There have been enough reports of issues with steel-cased ammo, pmag m3s not fitting, and the top rail being slightly loose that it might be worth it to hold off for a while.
Maybe I'll strike up a conversation with my contact at Beretta in the not-too-distant future and see if they're interested in a Maryland-Compliant version with a muzzle brake.
I too wouldn't mind then a little time to comment on the issues erwos notes.
