I'm 6'-4" and left-handed and was able to fit a Benelli Ultralight perfectly using the shim kit that came with the shotgun.
You must be 6'4" with allagator arms then because the shims don't do much in lenght of pull. Or you think that the gun fits you, but in reality it doesn't. I am all of 6'4" and have about a 2" spacer between the stock and pad. Not to mention having to raise the comb height too. I won't even get into cast! Anyways if it works for you that is great.
