As TT points out, fit is very important. Most stocks are dimensioned for the mythical average shooter. Depending on your stature and how it translates to length of pull, you may have to shorten a stock, of if you are tall with long arms, you will have to add somehow. I'm 6'4" and always had to add. If you are lucky in having to add, a recoil pad of the right thickness might do the trick. I have a side-by-side LeFever from the 20's and had to add a spacer and a recoil pad. Sadly, it sees little use. It was/is a long barrel bored modified and full, and that was before they had plastic shot collars. I patterned it once with shot collared rounds, and the modified barrel shoots full and the full is a super full with such rounds. Good for duck or goose, but realistically, little else.
