It sounds like a solid torso hit. It is not uncommon for people to be hit several times with a .45 and walk or run away. The idea that it is a magical one shot stopper is pretty much a myth.
The .45 is a pretty good stopper, but if you don't hit the heart or spine or major support structures such as the pelvic girdle or leg bones, it takes time to take effect, especially if hardball is used instead of expanding bullets.
I carry Speer Gold Dot in my Glock 30. Switched to that from HydraShok after finding out that the cops use them in their .40s.
Nice hefty 230-grain rounds, even with the cavity at the tip, and they feed very nicely, since they're a bit more rounded than the HydraShoks.
My 9mm HiPower would sometimes choke on HydraShoks since they're a bit too pointy for it - the edge of the cavity would catch on the feed ramp.
