Personally I’m not sure I’d run em. Titegroup is a fast burning powder, the 9 has a small case capacity and can generate pressures up to 35k. My experience has shown me I can generally find the sweet spot at below max loads using a fast burning powder. I’m gonna go out on a limb here guess that the min/max charge is probably separated by .4 grains at most.........JMO.
I just looked up your load on loaddata.com. While 4.3 grains is max with a lead bullet, they show 4.8 grains with a speer gold dot jacketed bullet. I would try a couple and see. Better yet, try them in a blackhawk with a 9mm cylinder. I am not familiar with those bullets or the coating, but if pushed too fast, without a perfect fit, I would immediately check for leading.
