Yup. "Stock Fit Is All", in shotty-guns.
If it's too long, you shoot low. If it's too short, you shoot high.
With proper drop and cast-off, when you mount the gun with your eyes closed and then open your eyes, you should be looking directly along the line of the barrel/rib; and you should not be low or high in alignment with the front sight.
John Satterwhite's comment was that the stock is the rear sight. Proper fit, proper sights, proper shooting.
And all these quail in my front yard are making me hungry!
