I've never noticed ejecta from a right port gun. I have always worn glasses or safety glasses, though. No doubt it is a nuisance for some.
My turkey guns, excepting an old Mossberg kept for sentimental reasons, are aluminum frame and break-action with tang safeties. If I were to buy a Mossberg pump for turkeys today, it would be a Mossberg 505AF. Those have a short mag tube which reduces weight.
It sure is nice to have so many options nowadays!
