Q: Is layaway available on this shotgun?

Q: Length of Pull info. what is Length of Pull and what does it matter? why i am asking: one of the reviews said "you must have long arms to run the pump effectively". this being 7+1 version is why i want to buy it over the normal 5+1 version. i have shorter arms than most men & i'm worried the additional distance to reach the pump handle might be problem for me to be comfortable with it. info given on the description lists the LOP 14.25 but the 5+1(shorter LOP?) no LOP listing to compare it.

Q: Can this shoot 3" shells out of the box? Want to shoot some 3" magnum
