Yes, there is a considerable difference in recoil between the long slide and the standard 5" model. There is even more recoil with the Commander size and yet more with the Officer size.
If you reload, there are lighter loads that will work just fine in a Commander sized gun that really tame recoil. You can replace the recoil spring with a lighter one and shoot 185gr bullets with a reduced powder charge. These are great for practice. For defense loads, put the factory recoil spring back in and use a full power load.
