You saw my pic in the gallery, I'm 6' and 240 lbs. Mine is a marine version size medium.
The only place you would need more adjusting would be in the shoulder straps, I have 4 holes remaining on the shoulder straps, at 1" per hole. I beleive you would be just fine with the medium size.
If not, you could always throw it on ebay and get double your money back....lol
