Back a few years ago when we had a similar crunch on everything related to guns/ammo/reloading, I came across a small lot of magnum small pistol primers. I reloaded a few hundred 115 and 124 gr 9mm cartridges with them. Never saw any pressure signs. Granted I was staying at the minimum according to my Speer manual (which tends to be a little more liberal) If they are all you can find, use em and like the others have said, reduce your max charge and watch for flat primers or if you are really over pressure cratered or pierced primers.
