During the primer shortage four years ago many people had to substitute mag small pistol primers for standard one. Reduce the charge a bit if you are at max by the book, or max on a worked up load that is at or near max. With a charge like you ask about a .1 Gr reduction will likely result in similar velocities. .2 at most.
Problems? In general, the least violent primer that ignites the powder well is going to be better for accuracy.
But hey, which one of us is good enough to prove it in a hand gun? Not me.
