Either hit it really really hard or buy a good qulity site pusher. Smith MPs are notorious for extremely tight sites.

Poster above has the correct answer, hit it harder! Unless you want to buy a sight pusher for about $100. S&W sights are notorious for being difficult to move. Either this or take the gun to someone local that has the tools.
I suspect you are trying to be too careful and just "tapping" it. Use a brass punch, not steel, and a hammer at least 16 oz. Clamp the slide in a vise to firmly hold it so you are not just moving the whole slide when you try to move the sight.

PAD THE VISE JAWS!!!! The plastic insert in some sliced meats makes a great non compressible pad. Wash it well first. Wetting the sight dovetail with Kroil helps.
You might want to be really sure it's the sights and not your trigger manipulation.

I hate dovetail rear sights until I get them just right which may be a time consuming process because I shoot well enough that if my gun is off to one side an inch and a half, I can tell.
Hitting an expensive pistol with a hammer and a drift is something not to be taken lightly. I’ve battered at least one rear sight, and it didn’t budge. So take the “Bigger Hammer” advice with some skepticism. A cheap $100 sight pusher from Amazon, sometimes is not much better. If you look closely, at least half of my guns have a rear sight with at least a tiny imperfection. But they all shoot centered.
I’ll bet there is an amateur gunsmith that frequents the range you go to, who would be happy to help you.

Factory sights on many new guns are really really hard to drift! Up until 3 years ago I never owned a sight pusher tool - I do now. I just do not feel good about pounding on sights with tritium vials in them. Not thrilled about marking them up either.
Sight Drifting Tips:
Remove the slide and place it flat on a hardwood board. If you try to drift sights on a soft surface the surface will absorb the impact instead of drifting the sights. Sometimes it helps greatly to have an assistant to hold the slide securely flat.
Use a dead blow ball peen hammer of appropriate weight which will transfer the most impact with the least amount of bounce back.
Use a well dressed punch of the correct size. I have punches with nylon tips, brass and steel. The nylon tip must be thin, just enough to protect the sight's finish. Any protector that is soft and too thick will absorb impact which will take away from the force needed to move the sight.
Put a piece of masking tape or pencil line on the slide at the very edge of where the sight is currently positioned. Use the witness mark to determine if and how far the sight is moving with each blow.
I bit the bullet and purchased a professional sight pusher a few years ago. Admittedly I do not use it often but when I do it works quite well. It seems with today's CNC production, tolerances have gotten tighter. Not only that, the sight pusher tool allows for much more precise movement and tends to avoid over drifting them. All in all, if you are gonna be in the game for the long haul, it might be a consideration.

Google "Wyoming Sight Drifter" it works well.
I have had luck using the Wyoming sight drifter

Ruger .22 pistols have insanely tight rear sights. I use the rim of an empty rimmed case as a punch - like a .30-30. I normally lay the slide on a sandbag.
