When I lived in california I had to pick up and deliver computer parts in some not so nice areas of L.A, during the Rodney King riots no less[

]. I carried a Browning Hi Power with Hydroshocks in it. And for practice I used handloaded FMJ ball ammo a buddy loaded for me. I thought about switching to Black Talons (this was a while ago) but they outlawed them before I could try some.
Number one key is not matter what you use make sure it is accurate enough for your use and competely reliable in your gun. If your gun doesn't like the Hydroshocks then by all means don't use them.
