I got a new to me Mossberg 500 with a 18 1/2 in. Barrel and Wood stock. Shot it yesterday for or the first time. I'm 73 and can still handle the recoil but I would rather reduce it as much as I can. The gun has what looks like a recoil pad but it's like a hard plastic. I don't see how it could and it does not feel like it reduces any recoil to me. Is it just for looks or is it supposed to really work.
