For practice, I also use the PMC. It's a great round IMO.
For defense, I use the silver tips from Winchester. Good value, since they come in boxes of 50 (so I can shoot some and still have some left from teh same batch)
I shot the Cor-Bon, but the recoil and flash seemed excessive. All 38 super rounds are +P, but the CorBon's seemed to be harsher. Given the old barrel, the "lightened" slide and the aluminum frame, I'll stick with Winchester and PMC.
