one thing i would suggest is try to get out and shoot one if you havent. and ill tell ya, 3 1/2 inch shells hurt. im 5'8'' 165-170 and i can only really shoot maybe 10 rounds before i have to take a break. now that being said, im not really a shotgun guy. dont even own one, my wife has a 20GA ithaca youth model, thats a fun little shotgun. not that easy for me to shoot due to it being a youth model, but its still a good time, light on the shoulder too. but if you determine that the 3 1/2 shells work for you, go for it. and be safe.
