Is there any particular reason for a heavier bullet? Most good 115s work pretty well for SD. They also shoot to similar POI as most practice ammo. That's something heavier bullets don't generally do. A lot of people like the newer 147s although I'm not one of them.
I personally like the 124 +P Gold Dots because of good performance, fairly easy to find and somewhat cheaper than many other loads...sometimes. They also shoot fairly close to POI at 15 yds. as WWB 115s in my G19. A bit high at 25 but not too bad.
