If you are a female (as your avatar suggests) then I would think it likely that you are shorter than the 6-foot male that your gun was designed for.
FIT is important in a lot more than shoes. If a stock is too short for you, there is a danger of hitting yourself in the mouth with your own thumb when you fire. At the other extreme, if the stock is too long for you, you can't hold the gun securely.... and it kicks the bejabbers out of you.
The suggestions above are good ones mostly. There IS 'managed-recoil' ammo; it works.
There ARE Trap loads, and they are mild.
Kick-Eze does make pretty good recoil pads and I DO second the motion there.
But when you get your recoil pad fitted to the gun, take it to a real stockmaker.... and have the GUN fitted to YOU. Likely there will be a chunk sawed off the butt of your gun and, in theory, the gun will kick worse.... but you won't notice that at all. You will be able to HOLD the thing securely and the felt recoil will be much LESS.
People rag at those silly old British .303 rifles with that idiotic butt that needs a huge screwdriver to remove. How many people know that the old model Lee-Enfield had FOUR different butt lengths (Bantam, Short, Normal, Long) and that each rifle was fitted to the man who carried it? It made learning how to shoot faster and it made achieving real ACCURACY a lot quicker and easier. And the later model (with the back sight over the action) actually had SIX different butts... for the same reason, with the same results.
You can doi exactly the same thing: fit YOUR gun to YOU.
It will kick you a lot less.
And YOU will enjoy shooting even more than you do now.
