Your CZ rifle and the over/ under shotgun are two different birds. The shotgun is made in Turkey and will not be of the same quality as your rifle. While the Turkish guns are indeed good value for the money, they are not the same as the CZ products built by CZ. I say this because I had both a Turkish/CZ SxS and over/under and I have a CZ (made by CZ) over/under combination gun. But don't get me wrong, the Turkish CZ's are a fine gun but they are designed for hunting, not high volume clays shooting if that is what you want to do. If high volume clays shooting is your goal and you want to spend less than $1000.00 but are intent on an O/U, then I would look for a used Browning or Beretta or SKB, something along that line. Gun fit refers to many things such as is the length of pull too long or too short, does your cheek sit where it should be on the stock and do you have a proper sight plain, do you have to move your head around to get it to fit the gun instead of the other way around. You have to handle the gun and see if it comes up naturally to your shoulder in a smooth motion and if it "feels right".
